PyPN is an extension that allows you to use Python to script almost anything in PN. This can be simple text formatting, or complex macros for automation.
See Install PyPN for installation instructions.
After PyPN is installed, go to View > Window > Scripts (or press Alt+F10). You should be able to see the Scripts menu, with the sample scripts listed.
Double click on a line in the Scripts window to run that script.
To edit the scripts, go to "\Program Files\Programmer's Notepad\Scripts" and look at text.py. There you'll see the source code for the sample scripts, and you can add your own. You may have to restart PN to show changes.
The PyPN extension makes it pretty easy to add your own features to Programmer's Notepad. PyPN exposes the underlying Scintilla interface to Python and this results in a very powerful scripting ability. The PyPN programmer has the PN objects, Scintilla editor, and the entire installed Python library ready for import.
To begin, start by creating a new document and selecting the "Python" scheme. Once the scheme is set to Python type pnscriptfile into the document, then press Ctrl+Alt+Space. This should auto-fill the document with this basic code template:
############################################################################### ## Script description ## By: your name here import pn import scintilla from pypn.decorators import script @script() def (): """ What this does """ pass
The top part of the file is a header area where you can fill in some information about your script, which may help should you decide to share your script or refer back to it at some point in the future.
The next few lines are the standard imports needed for most PyPN scripts. These will give you access to the pn library, the scintilla library, and will expose the @script() decorator that you can see on the next line down.
The script decorator allows PN to parse out some meta-data from the script file that lets your script appear in the list of scripts on the Scripts window (Alt+F10). Generally this would have the syntax: @script("Script Name", "Group")
However if this is left blank it will default to the name of the method for "Script Name" and will put the script in the "Python" group.
The next line is where you define you method. In this case lets create the method HelloPN.
############################################################################### ## Hello Programmer's Notepad ## By: PyPN Programmer import pn import scintilla from pypn.decorators import script @script() def HelloPN(): """ Say Hello To Programmer's Notepad """ newDoc = pn.NewDocument(None) editor = scintilla.Scintilla(newDoc) message = "Hello Programmer's Notepad!" editor.BeginUndoAction() editor.AppendText(len(message), message) editor.EndUndoAction() pass
Save this file as HelloPN.py inside of the <Programmers Notepad Home Dir>\scripts directory. Once saved, exit Programmer's Notepad and restart. When you bring up the scripts window you should see a new script under the Python group. Double clicking on this script will run it. If you do not see the script, then look in the output window for a Python error which may help you in determining what went wrong.
Taking a look at the method just defined:
python""" Say Hello To Programmer's Notepad """
The three quotes on an empty line begins a documentation comment. So this line aids in documenting what the script does.
pythonnewDoc = pn.NewDocument(None)
This line instructs PN to create a new document with no schema. Had we used pn.NewDocument("Python") we would have created a new Python document. Had we used pn.CurrentDoc() we not have created a new document but found a reference to the current document -- allowing us to append our message to the end of whatever document was currently selected.
pythoneditor = scintilla.Scintilla(newDoc)
To edit documents we need access to the Scintilla interface. This line creates a Scintilla editor object for the document we just created. We need an editor object to access the text of a document.
pythonmessage = "Hello Programmer's Notepad!"
This created a string with our message text in it. We will use this string to insert our message into the document.
pythoneditor.BeginUndoAction()
It is never any fun when an editor preforms an action that cannot be undone. This line will establish an "undo point" so that the user can undo the operation that our script did to the document. The user will be able to undo any operations preformed between this point and when the EndUndoAction() is called. In this case, pressing Ctrl-Z on the new document should remove our message.
pythoneditor.AppendText(len(message), message)
This line will append our message to the end of the document. The AppendText(len, text) function takes two arguments. The first parameter is the number of characters you would like it to take from the text string provided in the second parameter.
pythoneditor.EndUndoAction()
This line will mark and end of undo operations. It is advisable to ensure that you always make changes to documents inside of an undo block so that the user can revert any changes should they be disappointed in the results.
pass
This line has no effect. The pass statement in Python has no operation and is merely used as a place holder or marker. In this case it serves as a marker for the end of the current function. It can be removed with no effect upon the functionality or logic of the code.
For a list of user generated scripts please see the List of User-Submitted PyPN Scripts.

How do I copy a file in Python? I couldn't find anything under os.
copyfile(src, dst)
Copy the contents of the file named
import shutil
shutil.copy2('/dir/file.ext', '/new/dir/newname.ext')
or
shutil.copy2('/dir/file.ext', '/new/dir')
In case you are stuck with Python 2.3 (as I am) you may notice that there is no
def copyfile(source, dest, buffer_size=1024*1024):
"""
Copy a file from source to dest. source and dest
can either be strings or any object with a read or
write method, like StringIO for example.
"""
if not hasattr(source, 'read'):
source = open(source, 'rb')
if not hasattr(dest, 'write'):
dest = open(dest, 'wb')
while 1:
copy_buffer = source.read(buffer_size)
if copy_buffer:
dest.write(copy_buffer)
else:
break
source.close()
dest.close()
Use the shutil module.
copyfile(src, dst)
Copy the contents of the file named src to a file named dst. The destination location must be writable; otherwise, an IOError exception will be raised. If dst already exists, it will be replaced. Special files such as character or block devices and pipes cannot be copied with this function. src and dst are path names given as strings.
Take a look at filesys for all the file and directory handling functions available in standard Python modules.
Directory and File copy example - From Tim Golden's Python Stuff:
import os
import shutil
import tempfile
filename1 = tempfile.mktemp (".txt")
open (filename1, "w").close ()
filename2 = filename1 + ".copy"
print filename1, "=>", filename2
shutil.copy (filename1, filename2)
if os.path.isfile (filename2): print "Success"
dirname1 = tempfile.mktemp (".dir")
os.mkdir (dirname1)
dirname2 = dirname1 + ".copy"
print dirname1, "=>", dirname2
shutil.copytree (dirname1, dirname2)
if os.path.isdir (dirname2): print "Success"

Edited to add benchmark below.
You can wrap a generator with a lock. For example,
import threading
class LockedIterator(object):
def __init__(self, it):
self.lock = threading.Lock()
self.it = it.__iter__()
def __iter__(self): return self
def next(self):
self.lock.acquire()
try:
return self.it.next()
finally:
self.lock.release()
gen = [x*2 for x in [1,2,3,4]]
g2 = LockedIterator(gen)
print list(g2)
Locking takes 50ms on my system, Queue takes 350ms. Queue is useful when you really do have a queue; for example, if you have incoming HTTP requests and you want to queue them for processing by worker threads. (That doesn't fit in the Python iterator model--once an iterator runs out of items, it's done.) If you really do have an iterator, then LockedIterator is a faster and simpler way to make it thread safe.
from datetime import datetime
import threading
num_worker_threads = 4
class LockedIterator(object):
def __init__(self, it):
self.lock = threading.Lock()
self.it = it.__iter__()
def __iter__(self): return self
def next(self):
self.lock.acquire()
try:
return self.it.next()
finally:
self.lock.release()
def test_locked(it):
it = LockedIterator(it)
def worker():
try:
for i in it:
pass
except Exception, e:
print e
raise
threads = []
for i in range(num_worker_threads):
t = threading.Thread(target=worker)
threads.append(t)
t.start()
for t in threads:
t.join()
def test_queue(it):
from Queue import Queue
def worker():
try:
while True:
item = q.get()
q.task_done()
except Exception, e:
print e
raise
q = Queue()
for i in range(num_worker_threads):
t = threading.Thread(target=worker)
t.setDaemon(True)
t.start()
t1 = datetime.now()
for item in it:
q.put(item)
q.join()
start_time = datetime.now()
it = [x*2 for x in range(1,10000)]
test_locked(it)
#test_queue(it)
end_time = datetime.now()
took = end_time-start_time
print "took %.01f" % ((took.seconds + took.microseconds/1000000.0)*1000)

The goal is to get the array of family members made and print out the results in the order created. Is there any way to tidy this up :)?
// Our Person constructor
function Person(name,age)
{
this.name=name;
this.age=age;
}
// Now we can make an array of people
var family=new Array();
family[0]=new Person("alice", 40);
family[1]=new Person("bob", 42);
family[2]=new Person("michelle", 8);
family[3]=new Person("timmy", 6);
// loop through our new array
for(i=0;i<family.length;i++)
{
console.log(family[i].name);
}
There are some ways to tidy things up.
// Our Person constructor
This comment doesn't explain anything that isn't already known. Comments should not say what is happening, they should explain the purpose instead, where the code can not be made clear enough to provide such an explanation for you. Instead of explaining what the code is already fully capable of showing you from the code itself, it's better to use comments to explain why things occur, or to provide a broad overview instead.
function Person(name,age)
Spacing. A space after the comma is best practice to help aid in readability.
{
Coding techniques from other programming languages, such as putting the curly brace at the start of the next line, is not just a bad idea - it can actually break JavaScript. Due to syntax limitations in JavaScript and how automatic semicolon insertion works, it is a fundamental principle in JavaScript that placing the curly brace at the start of a new line, is a practice that results in more fragile code.
this.name=name;
this.age=age;
Spacing before and after the equals sign is best practice to help improve readability of the code.
}
That line is good, it has no problems.
// Now we can make an array of people
Explaining what is happening once again, which is not a good use for comments.
var family=new Array();
family[0]=new Person("alice", 40);
family[1]=new Person("bob", 42);
family[2]=new Person("michelle", 8);
family[3]=new Person("timmy", 6);
It is preferred for the sake of consistency to use [] instead of new Array.
You can also create those new Person objects at the same time as defining the array, for example with:
It is also a common convention in JavaScript to use single quotes to delimit strings instead of double. Both work, but single provides more convenience than double.
var family = [
new Person('alice', 40),
new Person('bob', 42),
new Person('michelle', 8),
new Person('timmy', 6)
];
Due to the duplication that we see here though, it may be worth considering storing the name/age in an array, and using a loop to create the new Person objects instead. Especially if more people are planned to be added in further development.
// loop through our new array
Another useless comment.
for(i=0;i<family.length;i++)
The i variable has not been declared so it is going to be a global one instead. That's a bad mistake. The best way to remedy that is to declare the i variable right at the start of the code, with the other var declaration.
Spacing should be added after the for word, which helps to reinforce that it is not a function name being called.
Also, spacing before and after the equals sign, after the semicolons, and before and after the less than sign for improved readability.
{
Should come after the closing parenthesis of the for statement, with a space separating the two.
console.log(family[i].name);
Be aware that Internet Explorer doesn't support console.log - there are shims though that help to provide support, such as https://github.com/kayahr/console-shim
}
No troubles with this line
So what we end up with is something like the following:
// Create and show family info
function Person(name, age) {
this.name = name;
this.age = age;
}
var family = [
new Person('alice', 40),
new Person('bob', 42),
new Person('michelle', 8),
new Person('timmy', 6)
],
i;
for (i = 0; i < family.length; i += 1) {
console.log(family[i].name);
}
I have also replaced i++ with i += 1 because I agree with Douglas Crockford, that incrementors and decrementors are not as good to use as other techniques that make it clearer what is going on.
For some details, see http://stackoverflow.com/questions/971312/why-avoid-increment-and-decrement-operators-in-javascript
Comments-I didn't create the comments. I just kept them there because of being lazy. So I'm ignoring any suggestions for that :). No offense to you.
As for readability, I prefer no spaces in stuff such as (name,age). It helps my readability.
I was mainly just asking for advice on how to shorten code, which you were able to answer with the array advice.
console.log is just the part of the program that I'm supposed to write. I mean, I'm using codecademy.com and they force me to write console.log. Though again, comments based on that don't help me shorten the code.
Thank you Paul for the array advice :).
Another potential way to do that is to use the forEach method instead, which allows you to simplify things, and you won't need that variable either.
family.forEach(function (person) {
console.log(person.name);
});
The forEach method is available on all modern web browsers. If you want it to succeed on Internet explorer, the forEach documentation page has compatibility code that adds the capability for web browsers that don't know how.
Wow, that's some efficient looking code.
Thanks for the advice Paul. |
How to display player's score on Pygame?
I'm a new programmer working on a memory game for my computer science summative.The game goes like this: the computer displays random boxes at random positions and then the user has to guess where the boxes are and click on it.
I'm basically done, except right now I'm trying to create like 5 different levels that range in level of difficulty. eg level 1 will display like 2 boxes and level 2 will display like 5, etc. And then if the user gets through all levels they can play again. I know its a lot but I really want to get an A on this.
But right now I'm stuck because it doesnt really work until I try to close the window, and even then it only goes halfway. Any help would be appreciated.

How to display player's score on Pygame? |
As you probably noticed in the table of Python software in the previous column, many of the Python tools for XML processing are available in the PyXML package. There are also XML libraries built into Python, but these are pretty well covered in the official documentation.
One of the things I'm going to do in these columns is provide brief information on significant new happenings relevant to Python-XML development, including significant software releases.
PyXML 0.8.1 has been released. Major changes include updated DOM support and the disabling of the bundled XSLT library from the default install. More on PyXML below.
The Fredrik "effbot" Lundh has kicked off a project to develop a graphical RSS newsreader in Python. Also, Mark Nottingham developed RSS.py, a Python module for processing RSS 0.9.x and 1.0 feeds. Mark is the author of an excellent RSS tutorial.
Eric Freese has released SemanText, a program for developing and managing semantic networks using XML Topic Maps. It can also build such topic maps contextually from general XML formats. It comes with a GUI for knowledge-base management.
There has been some talk on the XML-SIG about developing a general type library architecture in Python useful for plugging data types into schema, Web services and other projects.
Finally, in the previous column, I mentioned that the cDomlette XML parser supports XInclude and XML Base, but I neglected to mention that libxml's parser does as well. libxml also supports XML Catalogs. xmlproc also supports XML catalogs. Recent builds of 4Suite add XML and OASIS catalog support to cDomlette.
PyXML is available as source, Windows installer, and RPM. Python itself is the only requirement. Any version later than 2.0 will do, I recommend 2.2.1 or later. If your operating environment has a C compiler, it's easy to build from source. Download the archive, unpack it to a suitable location and run
python setup.py install
Which is the usual way to set up Python programs. It is automatically installed to the package directory of the python executable that is used to run the install command. You will see a lot of output as it compiles and copies files. If you'd rather suppress this, use "python setup.py --quiet install".
PyXML overlays the xml module that comes with Python. It replaces all the contents of the Python module with its own versions. This is usually OK because the two code bases are the same, except that PyXML has usually incorporated more features and bug fixes. It's also possible that PyXML has introduced new bugs as well. If you ever need to uninstall PyXML, just remove the directory "_xmlplus" in the "site-packages" directory of your Python installation. The original Python xml module will be left untouched.
The SAX support in PyXML is basically the same code as the built-in SAX library in Python. The main added feature is a really clever module, xml.sax.writers, which provides facilities for re-serializing SAX events to XML and even SGML. This is especially useful as the end point of a SAX filter chain, and I'll cover it in more detail in a future article on Python SAX filters. PyXML also adds the xmlproc validating XML parser which can be selected using the make_parser function. Base Python does not support validation.
PyXML builds a good deal of machinery over the skeleton of the DOM Node class that comes with Python. First of all, there is 4DOM, a big DOM implementation which tries to be more faithful to the DOM spec than to be naturally Pythonic. It supports DOM Level 2, both XML (core) and HTML modules, including events, ranges, and traversal. PyXML also provides more frequently updated versions of minidom and pulldom. Because there are many DOM implementations available for Python, PyXML also adds a system in xml.dom.domreg for choosing between DOM implementations according to desired features. Only minidom and 4DOM are currently registered, so it is not yet generally useful, but this should change. There is also a lot of material in the xml.dom.ext module, which is set aside, generally, for DOM extensions specific to PyXML. These extensions include mechanisms for reading and writing serialized XML that predate the DOM Level 3 facilities for this.
Creating 4DOM nodes is a matter of using the modules in xml.dom.ext.readers. The general pattern is to create a reader object, which can then be used to parse from multiple sources. For parsing XML, one would usually use xml.dom.ext.readers.Sax2, and for HTML, xml.dom.ext.readers.HtmlLib. Listing 1, demonstrates reading XML.
from xml.dom.ext.reader import Sax2
DOC = """<?xml version="1.0" encoding="UTF-8"?>
<verse>
<attribution>Christopher Okibgo</attribution>
<line>For he was a shrub among the poplars,</line>
<line>Needing more roots</line>
<line>More sap to grow to sunlight,</line>
<line>Thirsting for sunlight</line>
</verse>
"""
#Create an XML reader object
reader = Sax2.Reader()
#Create a 4DOM document node parsed from XML in a string
doc_node = reader.fromString(DOC)
#You can execute regular DOM operations on the document node
verse_element = doc_node.documentElement
#And you can even use "Pythonic" shortcuts for things like
#Node lists and named node maps
#The first child of the verse element is a white space text node
#The second is the attribution element
attribution_element = verse_element.childNodes[1]
#attribution_string becomes "Christopher Okibgo"
attribution_string = attribution_element.firstChild.data
Listing 2 demonstrates reading HTML. You need to be connected to the Internet to run it successfully.
Listing 2: Creating a 4DOM HTML node by reading from a URL
from xml.dom.ext.reader import HtmlLib
#Create an HTML reader object
reader = HtmlLib.Reader()
#Create a 4DOM document node parsed from HTML at a URL
doc_node = reader.fromUri("http://www.python.org")
#Get the title of the HTML document
title_elem = doc_node.documentElement.getElementsByTagName("TITLE")[0]
#title_string becomes "Python Language Website"
title_string = title_elem.firstChild.data
The HTML parser is pretty forgiving, but not as much so as most Web browsers. Some non-standard HTML will cause errors.
One can also output XML using the xml.dom.ext.Print and xml.dom.ext.PrettyPrint functions. One can output proper XHTML from appropriate XML and HTML DOM nodes using xml.dom.ext.XHtmlPrint and xml.dom.ext.XHtmlPrettyPrint. Pure white space nodes between elements can be removed using xml.dom.ext.StripXml and xml.dom.ext.StripHtml. There are other small utility functions in this module. Listing 3 is a continuation of listing 1 which takes the document node that was read, strips it of white space, and then re-serializes the result to XML.
Listing 3: Stripping white space and then writing the resulting XML
from xml.dom.ext import StripXml, Print
#Strip the white space nodes in place and return the same node
StripXml(doc_node)
#Print the node as serialized XML to stdout
Print(doc_node)
#Write the node as serialized XML to a file
f = open("tmp.xml", "w")
Print(doc_node, stream=f)
f.close()
Listing 4 illustrates creating a tiny XML document from scratch using standard DOM API, and printing the serialized result.
Listing 4: Creating a 4DOM document bit by bit and writing the result
from xml.dom import implementation
from xml.dom import EMPTY_NAMESPACE, XML_NAMESPACE
from xml.dom.ext import Print
#Create a document type node using the doctype name "message"
#A blank system ID and blank public ID (i.e. no DTD information)
doctype = implementation.createDocumentType("message", None, None)
#Create a document node, which also creates a document element node
#For the element, use a blank namespace URI and local name "message"
doc = implementation.createDocument(EMPTY_NAMESPACE, "message", doctype)
#Get the document element
msg_elem = doc.documentElement
#Create an xml:lang attribute on the new element
msg_elem.setAttributeNS(XML_NAMESPACE, "xml:lang", "en")
#Create a text node with some data in it
new_text = doc.createTextNode("You need Python")
#Add the new text node to the document element
msg_elem.appendChild(new_text)
#Print out the result
Print(doc)
Notice the use of EMPTY_NAMESPACE or None for blank URIs and ID fields. This is a Python-XML convention. Rather than using the empty string, which is, after all, a valid URI reference, None is used (EMPTY_NAMESPACE is merely an alias for None). This has the added value of being a bit more readable. If you run this, you'll see that no declaration is given for the XML namespace. This is because of the special status of that namespace. If you created elements or attributes in other namespaces, those namespace declarations would be rendered in the output.
4DOM is a useful tool for learning about DOM in general, but it's not a practical DOM for most uses. The problem is that it is very slow and memory intensive. A lot of effort goes into handling DOM arcana; in particular, the event system is a significant drag on performance, though it has some very interesting uses. I am one of the original authors of 4DOM, and yet I rarely use it any more. There are other, much faster DOM implementations which I'll be covering in future articles. Luckily, the lessons you learn experimenting with 4DOM are mostly applicable to other Python DOMs.
Two XML files can be different and yet have the same effective content to an XML processor. This is because XML defines that some differences are insignificant, such as the order of attributes, the choice of single or double quotes, and some differences in the use of character entities. Canonicalization, popularly abbreviated as c14n, is a mechanism for serializing XML which normalizes all these differences. As such, c14n can be used to make XML files easier to compare. One important application of this is security. You may want to use technology to ensure that an XML file has not been tampered with, but you might want this check to ignore insignificant lexical differences. The xml.dom.ext.c14n module provides canonicalization support for Python. It provides a Canonicalize function which takes a DOM node (most implementations should work), and writes out canonical XML.
PyXML includes XPath and XSLT implementations written completely in Python, but as of this writing, the XSLT module is still being integrated into PyXML and does not really work. If you need XSLT processing, you will want to get Python-libxslt, 4Suite, Pyana, or one of the other packages I mentioned in the last installment. The XPath support, however, does work and operates on DOM nodes. In fact, it can be a very handy shortcut from using DOM methods for navigating. The following snippet uses an XPath expression to retrieve a list of all elements in a DOM document which are in the XSLT namespace. If you want to run it, first of all prepend code to define "doc" as a DOM document node object.
from xml.ns import XSLT
#The XSLT namespace http://www.w3.org/1999/XSL/Transform
NS = XSLT.BASE
from xml.xpath import Context, Evaluate
#Create an XPath context with the given DOM node
#With no other nodes in the context list
#(list size 1, current position 1)
#And the given prefix/namespace mapping
con = Context.Context(doc, 1, 1, processorNss={"xsl": NS})
#Evaluate the XPath expression and return the resulting
#Python list of nodes
result = Evaluate("//xsl:*", context=con)
XPath expressions can also return other data types: strings, numbers, and boolean. The first two are returned as regular Python strings and floats. Booleans are returned as instances of a special class, xml.utils.boolean. This will probably change in Python 2.3, which has a built-in boolean type.
If you are making extensive use of XPath, you might still want to consider the implementation in 4Suite, which is a faster version of the one in PyXML, with more bug fixes as well.
I mentioned some of the other modules in PyXML in the last installment, including the xmlproc validating parser, in module xml.parsers.xmlproc, Quick Parsing for XML, in module xml.utils.qp_xml and the WDDX library, in module xml.marshal.wddx. Marshalling is the process of representing arbitrary Python objects as XML, and there is also a general marshaling facility in the xml.marshal.generic module. It has a similar interface to the standard pickle module. Listing 6 marshals a small Python dictionary to XML.
from xml.marshal.generic import Marshaller
marshal = Marshaller()
obj = {1: [2, 3], 'a': 'b'}
#Dump to a string
xml_form = marshal.dumps(obj)
The created XML looks as follows (line wrapping and indentation added for clarity):
<?xml version="1.0"?> <marshal> <dictionary id="i2"> <int>1</int> <list id="i3"><int>2</int><int>3</int></list> <string>a</string> <string>b</string> </dictionary> </marshal>
You can find more code examples in the demos directory of the PyXML package. The place to discuss PyXML or to report problems is the Python XML SIG mailing list.
In the next article, I'll offer a tour of 4Suite, which provides enhanced versions of some of PyXML's facilities, as well as some other unique features.

A handy Python script for parsing the O'Reilly book catalogue.
by Jacek Artymiak
I'm working on a on-line bookstore project, which I'd like to automate as much as possible. Things like book insertion and deletion ought to happen automatically, with only occasional need to mess with code or HTML. My choice of language for this project is Python, with a touch of urllib and re. Since one of the sources of book titles and ISBN numbers I use is the O'Reilly book catalogue, I thought I'd share this little script with other ORA fans.
#!/usr/bin/python
import urllib, re, sys
try:
page = urllib.urlopen('http://www.oreilly.com/catalog/prdindex.html')
except IOError, (errno, strerror):
sys.exit ("I/O error(%s): %s" % (errno, strerror))
title = ""
isbn = ""
price = ""
page = page.read()
page = page.replace("\n", "")
page = page.replace("\r", "")
page = page.replace("> ", ">")
page = page.replace(" ", " ")
page = page[page.find("<b>Examples</b></td>") + len("<b>Examples</b></td>"):]
while(1):
page = page[page.find("<tr ") + len("<tr "):]
if (len(page) == 1):
break
page = page[page.find("http://www.oreilly.com/catalog/"):]
if (len(page) == 1):
break
page = page[page.find("\">"):]
page = page[2:]
title = page[:page.find("</a>")]
page = page[page.find("\">"):]
page = page[2:]
isbn = page[:page.find("</td>")]
isbn = isbn.replace("-", "")
page = page[page.find("\">"):]
page = page[2:]
price = page[:page.find("</td>")]
print title + ":" + isbn + ":" + price

I'm using this sample code to connect to Facebook Chat over XMPP:
#!/usr/bin/python
import sleekxmpp
import logging
logging.basicConfig(level=logging.DEBUG)
def session_start(event):
chatbot.send_presence()
print('Session started')
chatbot.get_roster()
def message(msg):
if msg['type'] in ('chat','normal'):
print('msg received')
print(msg['body'])
msg.reply('Thanks').send()
jid = 'myusername@chat.facebook.com'
password = 'mypassword'
server = ('chat.facebook.com', 5222)
chatbot = sleekxmpp.ClientXMPP(jid,password)
chatbot.add_event_handler('session_start', session_start)
chatbot.add_event_handler('message', message)
chatbot.auto_reconnect = True
chatbot.connect(server)
chatbot.process(block=True)
Everything seems to be Ok, but when I run that code, I can't connect to Facebook server:

Am I missing something here? |
I have a group of variables named k1, k2 k3....k52. They variables are lists/numpy arrays depending on the scenario. Essentially I'd like to perform the same manipulation on them en masse within a loop, but am having trouble ierating over them. Essentially what i'd like is something like this:
for i in arange(0,52):
'k'+ str(i) = log10(eval('k' + str(i)))
Obviously i know the above wont work, but it gives the idea. My actual attempt is this:
for i in arange(0,10):
rate = eval('k' + str(i))
rate = np.array(rate,dtype=float)
rate = log10(rate)
rate.tolist()
vars()[rate] = 'k' + str(i)
(Its changed to a numpy array so i can log it, and then back to a list so i change the variable name back to what it was) Thanks for any help you can provide. I get the feeling this is something quite simple, but its escaping me at the moment.
edit: thanks very much for the answers, i should have explained that I can't really store them a set array, they need to remain as independent variables for reasons i don't really want to go into. |
So, I am trying to create a unittest.TestCase that creates several different databases with different member types and verifies something about the data(not important for this context). I wanted to use a generator to pass the necessary information from a global dict to the function which will take care of the object creation and verification.
Currently, it will only setUp, run, and tearDown the first variant of the test. How can I generate several distinct (i.e. varying parameters from a data structure such as a dict) calls to my method, which has to determine how to populate the database based on the member type? Each call should be run as a separate test and have the setUp and tearDown performed every time. The test case is being run with PyUnit in the Pydev GUI.
import sys, os, socket, shutil, unittest
# Global counter for test generation
testRun = 1
# test dictionary for generating multiple tests
basicMembers = {"Int" : 1}
# test operations to generate federations
def addItemAndGetSizeOf(basicMember, expectedValue, testFileName):
print "foo %s %s %s" % (basicMember, expectedValue, testFileName)
class BasicMembers(unittest.TestCase):
testFileName = "bar" + str(testRun)
def setUp(self):
global testRun
testRun += 1
print testRun
def tearDown(self):
pass
def testBasicMembers(self):
for basicMember, expectedValue in basicMembers.items():
yield addItemAndGetSizeOf, basicMember, expectedValue, self.testFileName
if __name__ == "__main__":
#import sys;sys.argv = ['', 'Test.testName']
unittest.main()

January 5th, 2012 at 9:26 pm by Dr. Drang
Last night I posted a TextExpander snippet that automated the procedure for generating Apple affiliate links for the items in iTunes and Mac App Stores. This morning I got an email from David Smith, who pointed out that affiliate links can be much shorter and easier to read if you’re willing to forgo the click tracking that LinkShare does. He linked to his own post from last week that describes the process very well. I liked David’s way of making affiliate links so much I’ve dropped last night’s snippet and made a new one.
The one advantage of the previous snippet is that it allows you to use LinkShare to track clicks as well as purchases. With the new snippet, you can track purchases only. To me, that’s a small price to pay to go from frightening looking URLs like this
http://click.linksynergy.com/fs-bin/stat?id=L4JhWyGwYTM
&offerid=146261&type=3&subid=0&tmpid=1826
&RD_PARM1=http%253A%252F%252Fitunes.apple.com%252Fus
%252Fapp%252Fnotesy-for-dropbox%252Fid386095500
%253Fmt%253D8%2526uo%253D4%2526partnerId%253D30
to nice, easy-to-read ones like this
http://itunes.apple.com/us/app/notesy-for-dropbox/
id386095500?mt=8&partnerId=30&siteID=L4JhWyGwYTM
(In both cases, I’ve inserted line breaks so you can see the whole thing without horizontal scrolling.)
As before, the links are generated through a Python script:
python:
1: #!/usr/bin/python
2:
3: from subprocess import check_output
4: from sys import stdout
5:
6: # The procedure followed here is taken from Apple's instructions for for linking:
7: # http://www.apple.com/itunes/affiliates/resources/documentation/linking-to-the-itunes-music-store.html
8:
9: # My affiliate ID.
10: myID = 'useyourown'
11:
12: # Get the URL from the clipboard.
13: clipURL = check_output('pbpaste')
14:
15: # Add my ID and the partnerId parameter to the URL. If there are already
16: # queries, add them as additional ones; if not, add them as the only ones.
17: if '?' in clipURL:
18: itemURL = '%s&partnerId=30&siteID=%s' % (clipURL, myID)
19: else:
20: itemURL = '%s?partnerId=30&siteID=%s' % (clipURL, myID)
21:
22: # Write it out
23: stdout.write(itemURL)
which you can copy and paste into a new TextExpander shell snippet:
The script is so much simpler than the LinkShare-ified version I wrote before, I’m almost embarrassed to post it. The only real logic is in Lines 17-20, which decide whether the partnerID parameter should be preceded by a & or a ?.
The one thing you’ll have to do if you want to use this snippet yourself is change Line 10 to put your own affiliate ID between the single quotation marks. You can pull your ID out of any affiliate link you might have generated in the past through Apple’s Link Maker tool. Look for a portion of the URL near the beginning that looks like
…/stat?id=L4JhWyGwYTM&offerid…
Your ID is the alphanumeric string between the = and the &.
You can, of course, use whatever abbreviation you like for the snippet; I settled on ;aal for “Apple affiliate link.”
The procedure for using this snippet is basically the same as the one I gave last night:
Find the item you want to link to in iTunes, the Mac App Store, or in your browser on one of Apple’s product web pages.
Copy the link to the item from either the popup menu (in iTunes or the App Store) or the toolbar (in your browser).
Switch to wherever you want to put the link and type
;aalto insert the URL.
As I said in last night’s post, I’d like to cut out Step 2 but can’t figure out how without resorting to GUI scripting, which I’m always leery of.
With this snippet, you can make affiliate links to
Thanks again to David for telling me about this simplification.
Update 1/7/12
If you’re using Snow Leopard or earlier, you probably have a version of Python earlier than Python 2.7, which means your subprocess library won’t have the check_output convenience function. You’ll need to use this version of the script instead:
python:
1: #!/usr/bin/python
2:
3: from subprocess import *
4: from sys import stdout
5:
6: # The procedure followed here is taken from Apple's instructions for for linking:
7: # http://www.apple.com/itunes/affiliates/resources/documentation/linking-to-the-itunes-music-store.html
8:
9: # My affiliate ID.
10: myID = 'useyourown'
11:
12: # Get the URL from the clipboard.
13: clipURL = clipURL = Popen('pbpaste', stdout=PIPE).communicate()[0]
14:
15: # Add my ID and the partnerId parameter to the URL. If there are already
16: # queries, add them as additional ones; if not, add them as the only ones.
17: if '?' in clipURL:
18: itemURL = '%s&partnerId=30&siteID=%s' % (clipURL, myID)
19: else:
20: itemURL = '%s?partnerId=30&siteID=%s' % (clipURL, myID)
21:
22: # Write it out
23: stdout.write(itemURL)
The difference are in Lines 3 and 13.
This script will work under Python 2.7, too, but Line 13 is distinctly more opaque.
Frankly, the whole subprocess module—and the popen2 module that preceded it as the Pythonic way of shelling out—stinks on ice. Anyone who wants to run shell commands from within a script already knows the shell syntax; forcing them to use an unnatural syntax, no matter how Pythonic it may be, is wasteful and stupid. Perl and Ruby are much smarter about this. I agree with this guy and will be checking out his Envoy library. |
Il linguaggio Python
Python
Python è un linguaggio di programmazione general purpose (utilizzabile quindi per gli scopi più diversi) estremamente di alto livello. La sua filosofia di progettazione pone l'accento sulla produttività del programmatore e sulla leggibilità del codice. Il suo nucleo ha una sintassi minimale con pochissimi comandi e con una semantica semplice, ma contiene un'ampia libreria standard con API per molte delle funzioni del sistema operativo su cui viene eseguito l'interprete. Il codice Python, seppur minimale, definisce oggetti di tipo liste (list), tuple (tuple), dizionari (dict) ed interi a lunghezza arbitraria (long).
Python supporta diversi paradigmi di programmazione: programmazione orientata agli oggetti (class), programmazione imperativa (def), e programmazione funzionale (lambda). Python ha un sistema di tipizzazione dinamica e un sistema automatico di gestione della memoria che utilizza il conteggio dei riferimenti (come Perl, Ruby e Scheme).
La prima versione di Python è stata rilasciata da Guido van Rossum nel 1991. Il linguaggio ha un modello di sviluppo aperto, basato su una comunità di sviluppatori gestita dalla Python Software Foundation, una associazione non-profit. Ci sono molti interpreti e compilatori che implementano il linguaggio Python, tra cui uno in Java (Jython). In questo breve approfondimento si farà riferimento all'implementazione C creata da Guido.
Sul sito ufficiale di Python[python] si possono trovare molti tutorial, la documentazione ufficiale e il manuale di riferimento della libreria standard del linguaggio.
Questo capitolo può essere saltato se si ha già familiarità con il linguaggio Python.
Avvio
Le distribuzioni binarie di web2py per Microsoft Windows e Apple Mac OS X già comprendono l'interprete Python.
Su Windows web2py può essere avviato con il seguente comando (digitato al prompt del DOS):
web2py.exe -S welcome
Su Apple Mac OS X digitare il seguente comando nella finestra del Terminale (dalla stessa cartella contenente web2py.app):
./web2py.app/Contents/MacOS/web2py -S welcome
Su una macchina Linux o su macchine Unix è molto probabile che Python sia già installato. In questo caso digitare al prompt dello shell il seguente comando:
python web2py.py -S welcome
Nel caso che Python 2.5 non sia presente dovrà essere scaricato e installato prima di eseguire web2py.
L'opzione della linea di comando -S welcome indica a web2py di eseguire la shell interattiva come se i comandi fossero inseriti in un controller dell'applicazione welcome, l'applicazione di base di web2py. Questo rende disponibili quasi tutte le classi, le funzioni e gli oggetti di web2py. Questa è l'unica differenza tra la shell interattiva di web2py e la normale linea di comando dell'interprete Python.
L'interfaccia amministrativa fornisce anche una shell utilizzabile via web per ogni applicazione. Per accedere a quella dell'applicazione "welcome" utilizzare l'indirizzo:
http://127.0.0.1:8000/admin/shell/index/welcome
Tutti gli esempi di questo capitolo possono essere provati sia nella shell standard di Python che nella shell via web di web2py.
help, dir
Nel linguaggio Python sono presenti due comandi utili per ottenere informazioni sugli oggetti, sia interni che definiti dall'utente, istanziati nello scope corrente.
Utilizzare il comando help per richiedere la documentazione di un oggetto (per esempio "1"):
>>> help(1)
Help on int object:
class int(object)
| int(x[, base]) -> integer
|
| Convert a string or number to an integer, if possible. A floating point
| argument will be truncated towards zero (this does not include a string
| representation of a floating point number!) When converting a string, use
| the optional base. It is an error to supply a base when converting a
| non-string. If the argument is outside the integer range a long object
| will be returned instead.
|
| Methods defined here:
|
| __abs__(...)
| x.__abs__() <==> abs(x)
...
e, poichè "1" è un intero, si ottiene come risposta la descrizione della classe int e di tutti i suoi metodi. Qui l'output del comando è stato troncato perchè molto lungo e dettagliato.
Allo stesso modo si può ottenere una lista di metodi dell'oggetto "1" con il comando dir:
>>> dir(1)
['__abs__', '__add__', '__and__', '__class__', '__cmp__', '__coerce__',
'__delattr__', '__div__', '__divmod__', '__doc__', '__float__',
'__floordiv__', '__getattribute__', '__getnewargs__', '__hash__', '__hex__',
'__index__', '__init__', '__int__', '__invert__', '__long__', '__lshift__',
'__mod__', '__mul__', '__neg__', '__new__', '__nonzero__', '__oct__',
'__or__', '__pos__', '__pow__', '__radd__', '__rand__', '__rdiv__',
'__rdivmod__', '__reduce__', '__reduce_ex__', '__repr__', '__rfloordiv__',
'__rlshift__', '__rmod__', '__rmul__', '__ror__', '__rpow__', '__rrshift__',
'__rshift__', '__rsub__', '__rtruediv__', '__rxor__', '__setattr__',
'__str__', '__sub__', '__truediv__', '__xor__']
Tipi
Python è un linguaggio dinamicamente tipizzato. Questo significa che le variabili non hanno un tipo e pertanto non devono essere dichiarate. I valori, d'altra parte, hanno un tipo. Si può interrogare una variabile per sapere il tipo del valore che contiene:
>>> a = 3
>>> print type(a)
<type 'int'>
>>> a = 3.14
>>> print type(a)
<type 'float'>
>>> a = 'hello python'
>>> print type(a)
<type 'str'>
Python include nativamente anche strutture dati come le liste e i dizionari.
str
Python supporta l'utilizzo di due differenti tipi di stringhe: stringhe ASCII e stringhe Unicode. Le stringhe ASCII sono delimitate dagli apici ('...'), dai doppi apici("...") o da tre doppi apici ("""..."""). I tre doppi apici delimitano le stringhe multilinea. Le stringhe Unicoode iniziano con il carattere u seguito dalla stringa che contiene i caratteri Unicode. Una stringa Unicode può essere convertita in una stringa ASCII scegliendo una codifica (encoding). Per esempio:
>>> a = 'this is an ASCII string'
>>> b = u'This is a Unicode string'
>>> a = b.encode('utf8')
Dopo aver eseguito questi tre comandi la variabile a è una stringa ASCII che memorizza caratteri codificati con UTF8. Internamente web2py utlizza sempre la codifica UTF8 nelle stringhe.
È possibile scrivere il valore delle variabili nelle stringhe in diversi modi:
>>> print 'number is ' + str(3)
number is 3
>>> print 'number is %s' % (3)
number is 3
>>> print 'number is %(number)s' % dict(number=3)
number is 3
L'ultima notazione è la più esplicita e la meno soggetta ad errori. Ed è pertanto da preferire.
Molti oggetti in Python, per esempio i numeri, possono essere convertiti in stringhe utlizzando str o repr. Questi due comandi sono molto simili e producono risultati leggermente diversi. Per esempio:
>>> for i in [3, 'hello']:
print str(i), repr(i)
3 3
hello 'hello'
Per le classi definite dall'utente str e repr possono essere definiti utilizzando gli speciali operatori __str__ e __repr__. Questi metodi sono brevemente descritti più avanti. Per ulteriori informazioni si può fare riferimento alla documentazione ufficiale di Python[pydocs] . repr ha sempre un valore di default.
Un'altra caratteristica importante delle stringhe in Python è che sono oggetti iterabili (sui quali si può eseguire un ciclo che ritorna sequenzialmente ogni elemento dell'oggetto):
>>> for i in 'hello':
print i
h
e
l
l
o
liste
I metodi principali delle liste in Python sono append (aggiungi), insert (inserisci) e delete (cancella):
>>> a = [1, 2, 3]
>>> print type(a)
<type 'list'>
>>> a.append(8)
>>> a.insert(2, 7)
>>> del a[0]
>>> print a
[2, 7, 3, 8]
>>> print len(a)
4
Le liste possono essere affettate (sliced) per ottenerne solo alcuni elementi:
>>> print a[:3]
[2, 7, 3]
>>> print a[1:]
[7, 3, 8]
>>> print a[-2:]
[3, 8]
e concatenate:
>>> a = [2, 3]
>>> b = [5, 6]
>>> print a + b
[2, 3, 5, 6]
Una lista è un oggetto iterabile quindi si può ciclare su di essa:
>>> a = [1, 2, 3]
>>> for i in a:
print i
1
2
3
Gli elementi di una lista non devono obbligatoriamente essere dello stesso tipo, ma possono essere qualsiasi tipo di oggetto Python.
tuple
Una tupla è come una lista, ma la sua dimensione e i suoi elementi sono immutabili, mentre in una lista sono mutabili. Se un elemento di una tupla è un oggetto gli attributi dell'oggetto sono mutabili. Una tupla è definita dalle parentesi tonde:
>>> a = (1, 2, 3)
Perciò, mentre questa assegnazione è valida per una lista:
>>> a = [1, 2, 3]
>>> a[1] = 5
>>> print a
[1, 5, 3]
l'assegnazione di un elemento all'interno di una tupla non è un'operazione valida:
>>> a = (1, 2, 3)
>>> print a[1]
2
>>> a[1] = 5
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: 'tuple' object does not support item assignment
La tupla, così come la lista, è un oggetto iterabile. È da notare che una tupla formata da un solo elemento deve includere una virgola alla fine:
>>> a = (1)
>>> print type(a)
<type 'int'>
>>> a = (1,)
>>> print type(a)
<type 'tuple'>
Le tuple, a causa della loro immutabilità, sono molto efficienti per l'impacchettamento (packing) degli oggetti. Le parentesi spesso sono opzionali:
>>> a = 2, 3, 'hello'
>>> x, y, z = a
>>> print x
2
>>> print z
hello
dict
Un dizionario (dict) in Python è una hash table che collega una chiave ad un valore. Per esempio:
>>> a = {'k':'v', 'k2':3}
>>> a['k']
v
>>> a['k2']
3
>>> a.has_key('k')
True
>>> a.has_key('v')
False
Le chiavi possono essere di un qualsiasi tipo che implementa il metodo __hash__ (int, stringa, o classe). I valori possono essere di qualsiasi tipo. Chiavi e valori diversi nello stesso dizionario non devono obbligatoriamente essere dello stesso tipo. Se le chiavi sono caratteri alfanumerici un dizionario può anche essere definito con una sintassi alternativa:
>>> a = dict(k='v', h2=3)
>>> a['k']
v
>>> print a
{'k':'v', 'h2':3}
Metodi utili di un dizionario sono has_key, keys, values e items:
>>> a = dict(k='v', k2='3)
>>> print a.keys()
['k', 'k2']
>>> print a.values()
['v', 3]
>>> print a.items()
[('k', 'v'), ('k2', 3)]
Il metodo items produce una lista di tuple ognuna contenente una chiave ed il suo valore associato.
Gli elementi di un dizionario o di una lista possono essere cancellati con il comando del:
>>> a = [1, 2, 3]
>>> del a[1]
>>> print a
[1, 3]
>>> a = dict(k='v', h2=3)
>>> del a['h2']
>>> print a
{'k':'v'}
Internamente Python utilizza l'operatore hash per convertire gli oggetti in interi ed utilizza quell'intero per determinare dove memorizzare l'oggetto.
>>> hash("hello world")
-1500746465
Indentazione del codice
Python utilizza l'indentazione per delimitare blocchi di codice. Un blocco inizia con una linea che termina con i due punti (":") e continua per tutte le linee che hanno lo stesso livello di indentazione o un livello maggiore. Per esempio:
>>> i = 0
>>> while i < 3:
>>> print i
>>> i = i + 1
>>>
0
1
2
Normalmente si utilizzano 4 spazi per ogni livello di indentazione È una buona regola non mischiare i caratteri di tabulazione (tab) con gli spazi, perchè questo potrebbe causare problemi.
for ... in
In Python è possibile ciclare (loop) sugli oggetti iterabili:
>>> a = [0, 1, 'hello', 'python']
>>> for i in a:
print i
0
1
hello
python
Una scorciatoia molto utilizzata è il comando xrange, che genera un iterabile senza memorizzare la lista degli elementi:
>>> for i in xrange(0, 4):
print i
0
1
2
3
Questo è equivalente alla sintassi in C/C++/C#/Java:
for(int i=0; i<4; i=i+1) { print(i); }
Un altro utile comando è enumerate, che esegue il conteggio all'interno di un ciclo:
>>> a = [0, 1, 'hello', 'python']
>>> for i, j in enumerate(a):
print i, j
0 0
1 1
2 hello
3 python
Esiste inoltre il comando range(a, b, c) che ritorna una lista di interi che ad iniziare dal valore a, incrementato del valore c e che si conclude con l'ultimo valore più piccolo di b. a ha come valore di default 0 e c ha default 1. xrange è simile ma non genera nessuna lista, solo un iteratore sulla lista, per questo è maggiormente utilizzato nei cicli.
Per uscire prematuramente da un ciclo si può utilizzare il comando break:
>>> for i in [1, 2, 3]:
print i
break
1
Per avviare la successiva iterazione del ciclo, senza eseguire tutto il blocco di codice che lo compone si può utilizzare il comando continue:
>>> for i in [1, 2, 3]:
print i
continue
print 'test'
1
2
3
while
Il ciclo while in Python è simile a quello di molti altri linguaggi di programmazione: ripete l'iterazione per un numero infinito di volte controllando la condizione all'inizio ciclo. Se la condizione è False il ciclo termina.
>>> i = 0
>>> while i < 10:
i = i + 1
>>> print i
10
Non esiste un costrutto di tipo loop ... until in Python.
def ... return
Questa è una tipica funzione in Python:
>>> def f(a, b=2):
return a + b
>>> print f(4)
6
Non c'è la necessità (e neanche la possibilità) di specificare i tipi degli argomenti o il tipo del valore che viene ritornato dalla funzione.
Gli argomenti delle funzioni possono avere valori di default e possono ritornare oggetti multipli:
>>> def f(a, b=2):
return a + b, a - b
>>> x, y = f(5)
>>> print x
7
>>> print y
3
Gli argomenti delle funzioni possono essere passati esplicitamente per nome:
>>> def f(a, b=2):
return a + b, a - b
>>> x, y = f(b=5, a=2)
>>> print x
7
>>> print y
-3
Le funzioni possono avere un numero variabile di argomenti:
>>> def f(*a, **b):
return a, b
>>> x, y = f(3, 'hello', c=4, test='world')
>>> print x
(3, 'hello')
>>> print y
{'c':4, 'test':'world'}
In questo esempio gli argomenti non passati per nome (3, 'hello') sono memorizzati nella lista a e gli argomenti passati per nome (c, test) sono memorizzati nel dizionario b.
Nel caso opposto una lista o una tupla può essere passata ad una funzione che richiede argomenti posizionali individuali tramite un'operazione di spacchettamento (unpacking):
>>> def f(a, b):
return a + b
>>> c = (1, 2)
>>> print f(*c)
3
e un dizionario può essere spacchettato per ottenere argomenti con nome:
>>> def f(a, b):
return a + b
>>> c = {'a':1, 'b':2}
>>> print f(**c)
3
if ... elif ... else
>>> for i in range(3):
>>> if i == 0:
>>> print 'zero'
>>> elif i == 1:
>>> print 'one'
>>> else:
>>> print 'other'
zero
one
other
"elif" significa "else if". Sia elif che else sono clausole opzionali. Può esistere più di un elif ma può essere presente un unico else. Condizioni di maggior complessità possono essere create utilizzando gli operatori not, and and or.
>>> for i in range(3):
>>> if i == 0 or (i == 1 and i + 1 == 2):
>>> print '0 or 1'
try ... except ... else ... finally
>>> try:
>>> a = 1 / 0
>>> except Exception, e
>>> print 'oops: %s' % e
>>> else:
>>> print 'no problem here'
>>> finally:
>>> print 'done'
oops: integer division or modulo by zero
done
Quando l'eccezione è generata viene intercettata dalla clausola except, che viene eseguita, mentre non viene eseguita la clausola else. Se non viene generata nessuna eccezione la clausola except non viene eseguita ma viene eseguita la clausola else. La clausola finally è sempre eseguita.
Possono esistere diverse clausole di tipo except per gestire differenti tipi di eccezione.
>>> try:
>>> raise SyntaxError
>>> except ValueError:
>>> print 'value error'
>>> except SyntaxError:
>>> print 'syntax error'
syntax error
Le clausole else e finally sono opzionali:

Per una descrizione dettagliata di ogni eccezione fare riferimento alla documentazione ufficiale di Python.
web2py espone solamente una nuova eccezione, chiamata HTTP. Quando questa viene generata ritorna una pagina di errore HTTP (per maggiori informazioni fare riferimento al Capitolo 4). Qualsiasi oggetto può essere generato come un'eccezione, ma è buona norma generare solamente oggetti che estendono le eccezioni predefinite.
classi
Poichè Python è dinamicamente tipizzato a prima vista le classi e gli oggetti possono sembrare strani. In effetti non è necessario definire le variabili membro (attributi) quando si dichiara una classe e differenti istanze di una stessa classe possono avere differenti attributi. Gli attributi sono generalmente associati con l'istanza e non con la classe (tranne nel caso in cui sono dichiarati come attributi di classe, che è l'equivalente delle variabili membro statiche in C++/Java.
Ecco un esempio:
>>> class MyClass(object): pass
>>> myinstance = MyClass()
>>> myinstance.myvariable = 3
>>> print myinstance.myvariable
3
pass è un comando che non fa nulla. In questo caso è utilizzato per definire una classe MyClass che non contiene nulla. MyClass() richiama il costruttore della classe (in questo caso il costruttore di default) e ritorna on oggetto che è un'istanza della classe. (object) nella definizione della classe indica che la nuova classe estende la classe predefinita object. Questo non è obbligatorio ma è una buona regola da seguire.
Ecco qui una classe più complessa:
>>> class MyClass(object):
>>> z = 2
>>> def __init__(self, a, b):
>>> self.x = a, self.y = b
>>> def add(self):
>>> return self.x + self.y + self.z
>>> myinstance = MyClass(3, 4)
>>> print myinstance.add()
9
Le funzioni dichiarate all'interno di una classe sono chiamate metodi. Alcuni metodi speciali hanno nomi riservati. Per esempio __init__ è il costruttore della classe. Tutte le variabili sono locali al metodo, tranne le variabili dichiarate all'esterno del metodo. Per esempio z è una variabile di classe, equivalente alle variabili membro statiche del C++, che contiene lo stesso valore per ogni istanza della classe.
È da notare che __init__ ha tre argomenti e il metodo add ne ha uno ma vengono chiamati rispettivamente con due e con zero argomenti. Il primo argomento rappresenta, per convenzione, il nome locale usato all'interno dei metodi per riferirsi all'istanza corrente della classe. Qui viene utilizzato self per riferirsi all'oggetto corrente, ma potrebbe essere utilizzato un qualsiasi nome. self ha lo stesso ruolo di *this in C++ o this in Java, ma self non è una parola chiave riservata. In questo modo si evitano ambiguità nella dichiarazione di classi nidificate, come nel caso di una classe definita in un metodo interno ad un altra classe.
Attributi, metodi ed operatori speciali
Gli attributi, i metodi e gli operatori di classe che iniziano con un doppio underscore (__) sono solitamente considerati privati, anche se questa è solamente una convenzione è non è una regola forzata dall'interprete.
Alcuni di questi sono parole chiave riservate ed hanno un significato speciale.
Per esempio:
__len__
__getitem__
__setitem__
possono essere utilizzati per creare un oggetto contenitore che agisce come se fosse una lista:
>>> class MyList(object)
>>> def __init__(self, *a): self.a = a
>>> def __len__(self): return len(self.a)
>>> def __getitem__(self, i): return self.a[i]
>>> def __setitem__(self, i, j): self.a[i] = j
>>> b = MyList(3, 4, 5)
>>> print b[1]
4
>>> a[1] = 7
>>> print b.a
[3, 7, 5]
Altri operatori speciali sono __getattr__ e __setattr__, che definiscono i modi di impostare e recuperare gli attributi della classe e __sum__ e __sub__, che possono eseguire l'overload degli operatori aritmetici. Sono già stati menzionati gli operatori speciali __str__ e __repr__. È consigliabile riferirsi a letture più approfondite per l'utilizzo di questi operatori.
File Input/Output
In Python è possibile aprire e scrivere in un file con:
>>> file = open('myfile.txt', 'w')
>>> file.write('hello world')
Allo stesso modo si può rileggere il contenuto di un file con:
>>> file = open('myfile.txt', 'r')
>>> print file.read()
hello world
In alternativa si possono leggere i file in modalità binaria con "rb", scrivere in modalità binaria con "wb", e aprire i file in modalità append con "a", secondo la notazione standard del C.
Il comando read ha un argomento opzionale che è il numero di byte da leggere. Si può saltare ad una qualsiasi posizione all'interno del file con il comando seek.
Si può leggere il contenuto del file con read:
>>> print file.seek(6)
>>> print file.read()
world
il file viene chiuso con:
>>> file.close()
sebbene spesso questo non sia necessario perchè il file è chiuso automaticamente quando la variable che lo rappresenta non è più nello scope.
Quando si usa web2py non si è a conoscenza di quale sia la directory corrente, perchè questo dipende da come web2py è configurato. Per questo motivo la variabilerequest.foldercontiene il path dell'applicazione corrente. I path possono essere concatenati con il comandoos.path.joindiscusso in seguito.
lambda
Ci sono casi in cui è necessario generare dinamicamente una funzione anonima. Questo può essere fatto utilizzando la parola chiave lambda:
>>> a = lambda b: b + 2
>>> print a(3)
5
L'espressione "lambda [a]:[b]" si può leggere come "una funzione con argomento [a] che ritorna [b]". Anche se la funzione è anonima può essere memorizzata in una variabile e in questo modo acquisisce un nome. Questo tecnicamente è diverso dall'utilizzo di una def, perchè è la variabile che fa riferimento alla funzione anonima che ha un nome, non la funzione stessa.
A cosa servono le lamba? In effetti sono molto utili perchè permettono di riscrivere una funzione in un altra impostando dei parametri di default senza dover creare una nuova funzione. Per esempio:
>>> def f(a, b): return a + b
>>> g = lambda a: f(a, 3)
>>> g(2)
5
Ecco un esempio più completo e più interessante: una funzione che controlla se un numero è primo:
def isprime(number):
for p in range(2, number):
if number % p:
return False
return True
Questa funzione, ovviamente, impiega molto tempo ad essere eseguita. Si supponga però di avere una funzione di cache cache.ram con tre argomenti: una chiave, una funzione e un numero di secondi:
value = cache.ram('key', f, 60)
La prima volta che viene chiamata la funzione cache.ram richiama la funzione f(), memorizza il risultato in un dizionario e ritorna il suo valore:
value = d['key']=f()
La seconda volta che la funzione cache.ram viene chiamata se la chiave è già nel dizionario e non è più vecchia del numero di secondi specificati (60), ritorna il valore corrispondente senza eseguire la chiamata alla funzione f().
value = d['key']
Come fare per memorizzare nella cache l'output della funzione isprime per ogni valore in input?
Ecco come:
>>> number = 7
>>> print cache.ram(str(number), lambda: isprime(number), seconds)
True
>>> print cache.ram(str(number), lambda: isprime(number), seconds)
True
L'output è sempre lo stesso, ma la prima volta che viene chiamata la funzione cache.ram viene eseguita anche isprime, la seconda volta no.
L'esistenza dilambdapermette di riscrivere una funzione esistente in termini di un differente set di argomenti.cache.ramecache.disksono due funzioni di cache di web2py.
exec, eval
A differenza di Java Python è un linguaggio completamente interpretato. Questo significa che si ha la possibilità di eseguire dei comandi Python inseriti in una stringa. Per esempio:
>>> a = "print 'hello world'"
>>> exec(a)
'hello world'
Cosa succede in questo caso? La funzione exec comanda all'interprete di richiamare se stesso ed eseguire il contenuto della stringa passata come argomento. È anche possibile eseguire il contenuto di una stringa con uno specifico contesto definito con i simboli inseriti in un dizionario:
>>> a = "print b"
>>> c = dict(b=3)
>>> exec(a, {}, c)
3
In questo caso l'interprete, quando esegue il contenuto della stringa a, vede i simboli definiti in c (b nell'esempio), ma non vede c o a. Questo è differente dall'esecuzione in un ambiente ristretto poichè exec non limita cosa può essere fatto dal codice interno; semplicemente definisce le variabili visibili al codice da eseguire.
Una funzione molto simile ad exec è eval, l'unica differenza è che si aspetta che l'argomento passato ritorni un valore che viene a sua volta ritornato:
>>> a = "3*4"
>>> b = eval(a)
>>> print b
12
import
Application Programming Interface) per molte delle librerie di sistema (spesso in un modo indipendente dal sistema operativo).
Per esempio, per utilizzare il generatore di numeri casuali:
>>> import random
>>> print random.randint(0, 9)
5
Questo codice stampa un intero tra 0 e 9 (incluso) generato casualmente, in questo caso il numero 5. La funzione randint è definita nel modulo random. È anche possibile importare un oggetto da un modulo nel namespace corrente:
>>> from random import randint
>>> print randint(0, 9)
o importare tutti gli oggetti da un modulo nel namespace corrente:
>>> from random import *
>>> print randint(0, 9)
o importare tutto il modulo in un nuovo namespace:
>>> import random as myrand
>>> print myrand.randint(0, 9)
Nel resto del libro saranno utilizzati principalmente oggetti definiti nei moduli os, sys, datetime, time e cPickle.
Tutti gli oggetti di web2py sono accessibili tramite un modulo chiamatogluon, e questo sarà il soggetto dei capitoli successivi. Internamente web2py utilizza diversi moduli di Python (per esempiothread), ma sarà raramente necessario accedere ad essi direttamente.
Nelle seguenti sezioni sono elencati i moduli di maggiore utilità.
os
Questo modulo fornisce una interfaccia alle API del sistema operativo. Per esempio:
>>> import os
>>> os.chdir('..')
>>> os.unlink('filename_to_be_deleted')
Alcune delle funzioni del moduloos, come per esempiochdir, NON DEVONO essere utilizzate in web2py perchè non sonothread-safe(cioè sicure per essere utilizzate in applicazioni con più thread eseguiti contemporaneamente).
os.path.join è estremamente utile; consente di concatenare i path in un modo indipendente dal sistema operativo.
>>> import os
>>> a = os.path.join('path', 'sub_path')
>>> print a
path/sub_path
Le variabili d'ambiente possono essere accedute con:
>>> print os.environ
che è un dizionario in sola lettura.
sys
sys contiene molte variabili e funzioni, ma quella che sarà maggiormente usata è sys.path. Contiene infatti una lista di path nei quali l'interprete Python ricerca i moduli. Quando si tenta di importare un modulo Python lo ricerca in tutte le cartelle elencate in sys.path. Se vengono installati moduli aggiuntivi in altre cartelle e si vuol far sì che Python li possa importare è necessario aggiungere il percorso al modulo in sys.path.
>>> import sys
>>> sys.path.append('path/to/my/modules')
Quando si esegue web2py Python rimane residente in memoria ed esiste perciò un unico sys.path mentre ci sono molti thread che rispondono alle richieste HTTP. Per evitare problemi di memoria è bene controllare se il percorso è già presente prima di aggiungerlo a sys.path:
>>> path = 'path/to/my/modules'
>>> if not path in sys.path:
sys.path.append(path)
datetime
L'uso del modulo datetime è illustrato nei seguenti esempi:
>>> import datetime
>>> print datetime.datetime.today()
2008-07-04 14:03:90
>>> print datetime.date.today()
2008-07-04
A volte potrebbe essere necessario marcare un dato con un orario UTC (invece che locale). In questo caso è possibile utilizzare la seguente funzione:
>>> import datetime
>>> print datetime.datetime.utcnow()
2008-07-04 14:03:90
Il modulo datetime contiene diverse classi: date, datetime, time e timedelta. La differenza tra due date, due datetime o due time è un timedelta:
>>> a = datetime.datetime(2008, 1, 1, 20, 30)
>>> b = datetime.datetime(2008, 1, 2, 20, 30)
>>> c = b - a
>>> print c.days
1
In web2py date e datetime sono utilizzati per memorizzare i corrispondenti tipi SQL quando sono passati o ritornati dal database.
time
Il modulo time differisce da date e datetime perchè rappresenta il tempo come numero di secondi a partire dall'inizio del 1970 (epoch).
>>> import time
>>> t = time.time()
1215138737.571
Si può far riferimento alla documentazione ufficiale di Python per le funzioni di conversione tra il tempo in secondi e il tempo come datetime.
cPickle
Questo è un modulo estremamente potente. Fornisce una serie di funzioni che possono serializzare quasi tutti gli oggeti Python, inclusi gli oggetti auto-referenziali. Ecco per esempio, un oggetto piuttosto strano:
>>> class MyClass(object): pass
>>> myinstance = MyClass()
>>> myinstance.x = 'something'
>>> a = [1 ,2, {'hello':'world'}, [3, 4, [myinstance]]]
ed ora:
>>> import cPickle
>>> b = cPickle.dumps(a)
>>> c = cPickle.loads(b)
In questo esempio b è la rappresentazione (serializzazione) di a in una stringa, e c è una copia di a generata dalla deserializzazione di b.
CPickle può anche serializzare e deserializzare da e su un file:
>>> cPickle.dumps(a, open('myfile.pickle', 'wb'))
>>> c = cPickle.loads(open('myfile.pickle', 'rb'))

Help me please |
My final goal is import some data from Google Site pages. I'm trying to use gdata-python-client (v2.0.17) to download a specific Content Feed:
self.client = gdata.sites.client.SitesClient(source=SOURCE_APP_NAME)
self.client.client_login(USERNAME, PASSWORD, source=SOURCE_APP_NAME, service=self.client.auth_service)
self.client.site = SITE
self.client.domain = DOMAIN
uri = '%s?path=%s' % (self.client.MakeContentFeedUri(), '[PAGE PATH]')
feed = self.client.GetContentFeed(uri=uri)
entry = feed.entry[0]
...
Resulted entry.content has a page content in xhtml format. But this tree doesn't content any plan text data from a page. Only html page struct and links.
For example my test page has
<div>Some text</div>
ContentFeed entry has only div node with text=None.
I have debugged gdata-python-client request/response and checked resolved data from server in raw buffer - any plan text data in content. Hence it is a Google API bug.
May be there is some workaround? May be i can use some common request parameter? What's going wrong here? |

$photoList is a global variable that gets declared and transformed inside getAnnonces(). In fact, it is returned by the function, so all you'd think this does is assign the variable to itself for some reason.
Well, it would, if the original programmer would have thought of declaring it as global outside of the function's scope.
$photoList exists as a global variable inside the function, but has a local scope outside of it. If this isn't some kind of meta-obfuscation I don't know what it is.

Can somebody explain to me why my old code:
code:
enum Foo { FOO_1, FOO_2 };
string GetInfo(Foo foo){
switch(foo) {
case FOO_1: return foo1;
case FOO_2: return foo2;
}
}
code:
string GetInfo(Foo foo){
stringstream stream;
switch(foo) {
case FOO_1:
stream << this->foo1;
break;
case FOO_2:
stream << this->foo2;
break;
default:
return "";
}
return stream.str();
}

How were foo1 and foo2 declared? Dynamically? Maybe someone's trying to avoid a race condition or memory leak?

Dear former intern: Just because .NET allows you to pass any object in the sender field of the event, does not mean you should use it to pass any arbitrary data. The first google result of "C# Custom Event" shows you exactly how to pass in custom event args.
Also, if your dialog only contains an ok and cancel button, you don't need to fire an event on when ok is pressed. Use the Dialog Result instead.

I got no code to show, but I've just found out about this bug:
A coworker of mine was saving hours in a database and chose to use the complete timestamp format (YYYY:MM:DD HH:mm:SS). However, he built the date using mktime() before sending it to the database. When there are parameters missing, mktime() completes them with the local date and time. For some reason, this made it so the main site would show an event's hour as right or wrong depending on the time of the day it was saved on in the admin panel.
I still don't really get how or why this all happens, but it made my day hell.

Ajout d'un paramètre dans la syntaxe pour choisir la qualité par des vidéos sans avoir à éditer le script.
Ajout d'explications en début de script sur son utilisation.
Ajout de la gestion des émissions en plusieurs parties (attention, il est nécessaire de télécharger toutes les parties en une seule commande, le script ne gèrera pas les différentes parties si certaines ont déjà été téléchargées).

LogFile = HomeDir + "/cplus_log"
HistoryFile = HomeDir + "/cplus_history"
UnwantedFile = HomeDir + "/cplus_unwanted"

Merci, j'ai réussi à faire fonctionner le script.

As-tu précisé les infos de cette émissions?
Dans le script il y a la liste des émissions de Canal + (ou du moins une partie) et en entête il est précisé qu'il faut renseigner:
L'ID de l'émission,
L'emplacement de la date,
Le nom de l'émission,
Le nom supposé du fichier
Je n'ai pas renseigné tous les champs pour toutes les émissions de Canal +, j'ai mis simplement les noms d'émission et les "supposés" ID de celles-ci.
Chacun doit renseigner les champs en fonction des émissions qui l'intéressent en attendant une évolution du script.
Dans ton cas, les infos devraient être les suivantes:
L'ID de l'émission: 215
Ensuite, comme les fichiers de cette émission ressemblent à ça sur le site:
LE_MEILLEUR_DU_HIER_EMISSION_121123_CAN_297682_video_HD.mp4
on devrait avoir:
L'emplacement de la date: 5 (0: LE, 1: MEILLEUR, 2: DU, 3: HIER, 4: EMISSION et 5: 121123 donc la date)
Le nom de l'émission: "Le meilleur du hier"
Le nom supposé du fichier: "LE_MEILLEUR_DU_HIER"
Donc tu dois remplacer la ligne:
#ShowList.append([215,4,"Le meilleur du hier"]) # 63 107 110 112 ?
par:
ShowList.append([215,5,"Le meilleur du hier","LE_MEILLEUR_DU_HIER"]) # 63 107 110 112 ?

Faut-il utiliser python ? ou le terminal/konsol suffit ?

Edit: https://github.com/agiliq/merchant/blob/master/billing/gateways/authorize_net_gateway.pylooks pretty nice, haven't tried it yet.
Edit: [For the next project I have that uses authorize.net, I'm going to take a close look at: http://github.com/zen4ever/django-authorizenet It looks pretty nice. I don't think that it has support for recurring payments though.]
In the past I have made little one-off implementations.
For simple post to the AIM payment gateway, you can use something like this:
URL = 'https://test.authorize.net/gateway/transact.dll'
API = {'x_login':'XXX',
'x_tran_key':'XXX', 'x_method':'CC', 'x_type':'AUTH_ONLY',
'x_delim_data':'TRUE', 'x_duplicate_window':'10', 'x_delim_char':'|',
'x_relay_response':'FALSE', 'x_version':'3.1'}
def call_auth(amount, card_num, exp_date, card_code, zip_code, request_ip=None):
'''Call authorize.net and get a result dict back'''
import urllib2, urllib
payment_post = API
payment_post['x_amount'] = amount
payment_post['x_card_num'] = card_num
payment_post['x_exp_date'] = exp_date
payment_post['x_card_code'] = card_code
payment_post['x_zip'] = zip_code
payment_request = urllib2.Request(URL, urllib.urlencode(payment_post))
r = urllib2.urlopen(payment_request).read()
return r
def call_capture(trans_id): # r.split('|')[6] we get back from the first call, trans_id
capture_post = API
capture_post['x_type'] = 'PRIOR_AUTH_CAPTURE'
capture_post['x_trans_id'] = trans_id
capture_request = urllib2.Request(URL, urllib.urlencode(capture_post))
r = urllib2.urlopen(capture_request).read()
return r
To authorize, you do something like:
r = authorize.call_auth(
unicode(decimal_total),
request.POST.get('card_num'),
request.POST.get('exp_date'),
request.POST.get('card_code'),
request.POST.get('zip_code') if request.POST.get('zip_code') else address.zip_code,
)
if r.split('|')[0] == '1':
# it's good, we have authorized the card...
else:
error = "%s Please try again." % (r.split('|')[3])
then, we can capture:
r = authorize.call_capture(trans_id) # r.split('|')[6] in first response..
if r.split('|')[0] == '1':
# we captured it.
else:
error = r.split('|')[3]
There are more options, ways to request, nuances in the response to parse... I assume b/c A in AIM stands for advanced that all of the authorize.net options are available.
http://developer.authorize.net/guides/AIM/
I know that your question is what lib is best .. well, it might be easiest just to implement your own little bit of ad-hoc request and response for your specific requirements rather than trying to trove through an api on top of an api. |
I am trying to write my very first python script. This was working but then after some slight refactoring I have, apparently, broken the indentation. I can not determine what is the problem. The interpretor complains about the following method. Can someone point it out?
def dataReceived(self, data):
a = data.split(':')
print a
if len(a) > 1:
command = a[0]
content = a[1]
msg = ""
if command == "iam":
self.name = content
msg = self.name + " has joined"
elif command == "msg":
msg = self.name + ": " + content
print msg
The error reads: File "python_server.py", line 17 a = data.split(':') ^ IndentationError: expected an indented block |
In the logging howto documentation there is this example:
import logging
# create logger
logger = logging.getLogger('simple_example')
logger.setLevel(logging.DEBUG)
# create console handler and set level to debug
ch = logging.StreamHandler()
ch.setLevel(logging.DEBUG)
# create formatter
formatter = logging.Formatter('%(asctime)s - %(name)s - %(levelname)s - %(message)s')
# add formatter to ch
ch.setFormatter(formatter)
# add ch to logger
logger.addHandler(ch)
Why I should set the level to logging.DEBUG twice, for logger, and for the streamhandler?I understand ch.setLevel(logging.DEBUG) will set the debug level for the stream handler. But what the effect is of setting the level to logger? Where this level is reflected?
I get the same console output if I change the level for example to info either to the logger or to the streamhandler That is:
...........
logger.setLevel(logging.INFO)
............
ch.setLevel(logging.DEBUG)
gives the same output in console than
...........
logger.setLevel(logging.DEBUG)
............
ch.setLevel(logging.INFO)

ClipStack is a Programmer's Notepad clipboard stack. It allows the user to select text and copy the text, which gets pushed onto a stack. Later this text can be pasted, which then pops the text off of this stack.
So, for example, if the user copies item A, then item B, and then item C, all using ClipStack; then they could then paste these items back in the order: Item C, Item B, Item A.
ClipStack does copy the the text into the clipboard so that you can paste the current selection in another application, but this will not pop an item off of the stack.
When pasting using ClipStack the current contents of the clipboard are replaced with the item on the top of the stack. This means that anything currently in the clipboard will be lost.
What ClipStack does not do is push the current clipboard onto the stack.
ClipStack could be improved by the addition of a clipboard aware python module that would allow the current clipboard to be used as the top item of the stack. This would allow the snippet to better interact with other applications.

After configuring and building PETSc, I have successfully been able to run several examples. In particular, I am working with this example. I have been able to run the program using the following commands:
make ex2 mpiexec -n 4 ./ex2 -m 40 -n 40
which produces the following output:
Norm of error 0.000642883 iterations 26Norm of error 0.000642883 iterations 26Norm of error 0.000642883 iterations 26Norm of error 0.000642883 iterations 26
This seems to tell me that the same problem was solved 4 times, rather than once by four processors in parallel. Suspicious, I ran the program again using
mpiexec -n 4 ./ex2 -m 40 -n 40 -log_summary
which produced the following output (note that it says that ./ex2 was run with only 1 processor:

Possible, mais c’est probablement plus compliqué… ce compteur est presque immaintenable.
Mais bon, dans un futur plus ou moins proche, on va refaire un compteur propre pour le TdCT. Du coup, il s’adaptera ici en un clin d’œil.

c'est marrant nesthib m'a dit la même chose mais quand personne le sais ....
donc en attendant si on veut bien continuer à m'aider j’apprends le python et j'arriverai peut être à avoir un compteur viable en attendant un compteur plus maintenable et en phase avec python 2.7.3 alors que le script de tshirtman est prévu pour du python 2.6.*

... bonjour !
Une seconde, on est samedi
@ljere:
spli permet de séparer une chaine en n morceaux séparés par le caractère donné. En prenant la date affichée : Hier à 21:19 ou Aujourd'hui à 08:56
on obtient alors un tableau du type [0] => "Hier", [1] => "à", [2] => "21:19"
Ensuite le triple split, resplite la chaine et utilise le 3eme élément pour tenter d'en extraire l'heure. le split avec '<' est inutile dans ce cas, il a du être rajouté à une époque lointaine (ancien forum ?). On obtient donc un seul élément égal au 3eme élément déjà pris en compte ("21:19"), puis on split par le ":" pour obtenir l'heure et on s'intéresse aux heures comprises entre 5 et 24.
Le deuxième partie s'intéresse aux heures entre 0 et 5.
Au final, tu obtiens donc les informations pour les dernières 24 heures, et on peut, dès lors, supposer que le compteur se lance tous les jours à 5h00 du matin
PS: j'ai pas répondu en mp : c'était déjà fait, et puis ça peut en intéresser d'autres

Re : Topic des lève-tôt… Faisons manger leurs caleçons aux couche-tard! [4]
donc comme pour nous on s’intéresse à une période de 6h à 9h
if (
(str_date.split(' ')[0] in ["Aujourd\'hui"]
and int(str_date.split(' ')[2].split(':')[6]) in range(8))
):
comme 9h est exclu je doit bien mettre 8?
En fait j'aurai plutôt mis ça :
if (
(str_date.split(' ')[0] in ["Aujourd\'hui"]
and int(str_date.split(' ')[2].split(':')[0]) in range(5,8))
):
Car :
- je ne sais pas pourquoi tu mets 6 au lieu de 0 dans le tableau : quand tu coupes 05:34 en chaines par rapport à ":", tu obtiens un tableau de deux éléments : "0" => "05", "1" => "34"
- Il faut s'occuper uniquement de 5 à 8 heures
Voilà
PS: Ah oui, ça à l'air facile python ou pas ?

I have written a python script to parse an HTML page, get some strings and then write to a mysql table. I am using the MySQLDb module for the database connection. The strings retrieved are encoded in ISO-8859-7 (Greek), which is the default encoding in the MySQL table as well. The code which produces the exception is the following :
def db_write(list) :
import MySQLdb as sql
try :
con = sql.connect(//database info here//)
except :
print "could not connect to database"
exit()
cur = con.cursor()
for i in my_range (8,len(list)-2,2) :
query = 'INSERT INTO as_doy VALUES (%s,"%s")' % (list[i],list[i+1])
print query
try :
cur.execute(query)
con.commit()
except :
print "failed"
con.rollback()
con.close()
The exception i get is ERROR 1366 (HY000): Incorrect string value: '\xEF\xBF\xBD\xEF\xBF\xBD...'
I have tried encoding the strings in utf-8, decoding and re-encoding in iso-8859-7, but nothing has worked for me yet. |
Background
I have two python processes that need to communicate with each other. The comminication is handled by a class named Pipe. I made a seperate class for this because most of the information that needs to be communicated comes in the form of dictionaries so Pipe implements a pretty simple protocol for doing this.
Here is the Pipe constructor:
def __init__(self,sPath):
"""
create the fifo. if it already exists just associate with it
"""
self.sPath = sPath
if not os.path.exists(sPath):
try:
os.mkfifo(sPath)
except:
raise Exception('cannot mkfifo at path \n {0}'.format(sPath))
self.iFH = os.open(sPath,os.O_RDWR | os.O_NONBLOCK)
self.iFHBlocking = os.open(sPath,os.O_RDWR)
So ideally I would just construct a Pipe in each process with the same path and they would be able to talk nice.
I'm going to skip out stuff about the protocol because I think it is largely unnecessary here.
All read and write operations make use of the following 'base' functions:
def base_read_blocking(self,iLen):
self.lock()
lBytes = os.read(self.iFHBlocking,iLen)
self.unlock()
return lBytes
def base_read(self,iLen):
print('entering base read')
self.lock()
lBytes = os.read(self.iFH,iLen)
self.unlock()
print('exiting base read')
return lBytes
def base_write_blocking(self,lBytes):
self.lock()
safe_write(self.iFHBlocking,lBytes)
self.unlock()
def base_write(self,lBytes):
print('entering base write')
self.lock()
safe_write(self.iFH,lBytes)
self.unlock()
print('exiting base write')
safe_write was suggested in another post
def safe_write(*args, **kwargs):
while True:
try:
return os.write(*args, **kwargs)
except OSError as e:
if e.errno == 35:
import time
print(".")
time.sleep(0.5)
else:
raise
locking and unlocking is handled like this:
def lock(self):
print('locking...')
while True:
try:
os.mkdir(self.get_lock_dir())
print('...locked')
return
except OSError as e:
if e.errno != 17:
raise e
def unlock(self):
try:
os.rmdir(self.get_lock_dir())
except OSError as e:
if e.errno != 2:
raise e
print('unlocked')
The Problem
This sometimes happens:
....in base_read
lBytes = os.read(self.iFH,iLen)
OSError: [Errno 11] Resource temporarily unavailable
Sometimes it's fine.
The Magical Solution
I seem to have stopped the problem from happening. Please note this is not me answering my own question. My question is explained in the next section.
I changed the read functions to look more like this and it sorted stuff out:
def base_read(self,iLen):
while not self.ready_for_reading():
import time
print('.')
time.sleep(0.5)
lBytes = ''.encode('utf-8')
while len(lBytes)<iLen:
self.lock()
try:
lBytes += os.read(self.iFH,iLen)
except OSError as e:
if e.errno == 11:
import time
print('.')
time.sleep(0.5)
finally:
self.unlock()
return lBytes
def ready_for_reading(self):
lR,lW,lX = select.select([self.iFH,],[],[],self.iTimeout)
if not lR:
return False
lR,lW,lX = select.select([self.iFHBlocking],[],[],self.iTimeout)
if not lR:
return False
return True
The Question
I'm struggling to find out exactly why it is temporarily unavailable. The two processes cannot access the actual named pipe at the same time due to the locking mechanism (unless I am mistaken?) so is this due to something more fundamental to fifos that my program is not taking into account?
All I really want is an explanation... The solution I found works but it looks like magic. Can anyone offer an explanation?
System
Ubuntu 12.04,
Python3.2.3 |
Background
From the documentation example here, one can easily produce the following contour plot with the code snippet.
import matplotlib
import numpy as np
import matplotlib.cm as cm
import matplotlib.mlab as mlab
import matplotlib.pyplot as plt
matplotlib.rcParams['xtick.direction'] = 'out'
matplotlib.rcParams['ytick.direction'] = 'out'
delta = 0.025
x = np.arange(-3.0, 3.0, delta)
y = np.arange(-2.0, 2.0, delta)
X, Y = np.meshgrid(x, y)
Z1 = mlab.bivariate_normal(X, Y, 1.0, 1.0, 0.0, 0.0)
Z2 = mlab.bivariate_normal(X, Y, 1.5, 0.5, 1, 1)
# difference of Gaussians
Z = 10.0 * (Z2 - Z1)
# Create a simple contour plot with labels using default colors. The
# inline argument to clabel will control whether the labels are draw
# over the line segments of the contour, removing the lines beneath
# the label
plt.figure()
CS = plt.contour(X, Y, Z)
plt.clabel(CS, inline=1, fontsize=10)
plt.title('Simplest default with labels')
My Goal
I have obtained my contour plot and meanwhile got the matplotlib.contour.QuadContourSet instance CS. In the example snippet, CS is only used for clabel(). However for my case, I need to obtain either the equation of the contour line or the coordinate set for further computation.
How can I extract the coordinates of the contour line from the instance CS? ORHow can I achieve it in other ways?
I bet there must be a way of doing so. Otherwise, the contour thing is only a "vase for visualization" then. |
When I run this simple code:
from pylab import *
import numpy as np
X = [];
Y = [];
for i in range (0,10):
X.append(i)
Y.append(i)
plot(X,Y)
show()
I don't get any window. I tried to replace show with draw with the same result.
I'm using python version 3.2.2
How can I show the window/plot than (apart from printing it to file and open the file).
Note, I'm using this example: |
employees = []
for i in range(0,10):
emp = Employee(i)
emp.first_name = "%s-%s"%("first name", i)
emp.last_name = "%s-%s"%("last_name", i)
emp.desgination = "%s-%s"%("engineer", i)
employees.append(emp)
ids = [e.eid for e in employees]
Following is my class definition:
class Employee:
_fields = {}
def __init__(self, eid):
self.eid = eid
def __getattr__(self, name):
return self._fields.get(name)
def __setattr__(self,name,value):
self._fields[name] = value
def __str__(self):
return str(self._fields)
def __unicode__(self):
return str(self._fields)
The issue is that when I print ids, it contains 10 times 9... i.e.
[9, 9, 9, 9, 9, 9, 9, 9, 9, 9]
It seems that the same emp variable is being overwritten. I am not sure what going wrong. Though I am a Java coder but I thought I had a fair idea of Python as well. |
I'm attempting to use the python logging module to do complex things. I'll leave the motivation for this design out because it would greatly lengthen the post, but I need to have a root logger that spams a regular log file for our code and libraries that use logging -- and a collection of other loggers that go to different log files.
The overall setup should look like this. I will do everything to stdout in this example to simplify the code.
import logging, sys
root = logging.getLogger('')
top = logging.getLogger('top')
bottom = logging.getLogger('top.bottom')
class KillFilter(object):
def filter(self, msg):
return 0
root_handler = logging.StreamHandler(sys.stdout)
top_handler = logging.StreamHandler(sys.stdout)
bottom_handler = logging.StreamHandler(sys.stdout)
root_handler.setFormatter(logging.Formatter('ROOT'))
top_handler.setFormatter(logging.Formatter('TOP HANDLER'))
bottom_handler.setFormatter(logging.Formatter("BOTTOM HANDLER"))
msg_killer = KillFilter()
root.addHandler(root_handler)
top.addHandler(top_handler)
bottom.addHandler(bottom_handler)
top.addFilter(msg_killer)
root.error('hi')
top.error('hi')
bottom.error('hi')
This outputs
ROOTBOTTOM HANDLERROOT
The second root handler call should not because according to logging documentation the msg_killer will stop the message from going up to the root logger. Obviously the documentation could use improvement.
Edit: removed my "in the moment" harsh words for python logging. |
I am wrapping a library which was written in C++ to Python API libwebqq
There is a type which is defined in boost function .
typedef boost::function<void (std::string)> EventListener;
Python level can define "EventListener" variable callbacks.
There is also a map structure in C++ level which is event_map in class Adapter. The key type of event_map is a QQEvent enum type and the value type of event_map is class "Action" which wraps EvenListener.
class Action
{
EventListener _callback;
public:
Action (){
n_actions++;
}
Action(const EventListener & cb ){
setCallback(cb);
}
virtual void operator()(std::string data) {
_callback(data);
}
void setCallback(const EventListener & cb){
_callback = cb;
}
virtual ~Action(){ std::cout<<"Destruct Action"<<std::endl; n_actions --; }
static int n_actions;
};
class Adapter{
std::map<QQEvent, Action > event_map;
public:
Adapter();
~Adapter();
void trigger( const QQEvent &event, const std::string data);
void register_event_handler(QQEvent event, EventListener callback);
bool is_event_registered(const QQEvent & event);
void delete_event_handler(QQEvent event);
};
"register_event_handler" in class Adapter is the API to register a callback function to related event. And C++ back end will call it if event happened. But we need to implement the callbacks in python level. And I wrapped the callback type in "callback.i"
The problem is , when I call the register_event in test python script, a type error always occurs:
Traceback (most recent call last):
File "testwrapper.py", line 44, in <module>
worker = Worker()
File "testwrapper.py", line 28, in __init__
a.setCallback(self.on_message)
File "/home/devil/linux/libwebqq/wrappers/python/libwebqqpython.py", line 95, in setCallback
def setCallback(self, *args): return _libwebqqpython.Action_setCallback(self, *args)
TypeError: in method 'Action_setCallback', argument 2 of type 'EventListener const &'
Destruct Action
Please help to figure out the root cause of this type error and a solution to this problem. |
Here is one simple way.
def isComposedOf(A, B):
bset = set(B)
for c in A:
if c not in bset:
return False
return True
This algorithm walks each string once, so it runs in O(len(A) + len(B)) time.
When the answer is yes, you cannot do better than len(A) comparisons even in the best case, because no matter what you must check every letter. And in the worst case one of the characters in A is hidden very deep in B. So O(len(A) + len(B)) is optimal, as far as worst-case performance is concerned.
Similarly: when the answer is no, you cannot do better than len(B) comparisons even in the best case; and in the worst case the character that isn't in B is hidden very deep in A. So O(len(A) + len(B)) is again optimal.
You can reduce the constant factor by using a better data structure for bset.
You can avoid scanning all of B in some (non-worst) cases where the answer is yes by building it lazily, scanning more of B each time you find a character in A that you haven't seen before. |
I want to write the text (which I get from AJAX) to a file, and then read it.
The following code for read the content from a file
handle=open('file','r+')
var=handle.read()
print var
The following code for writing the content to the file
handle1=open('file.txt','r+')
handle1.write("I AM NEW FILE")
handle1.close()
If you can use this in Django view... try somethink like this:
def some_view(request):
text = request.POST.get("text", None)
if text is not None:
f = open( 'some_file.txt', 'w+')
f.write(text)
f.close()
return HttpResponse()
f = open( 'filename.txt', 'w+' )
f.write( 'text' )
f.close()
f = open( 'filename.txt', 'r' )
for line in f:
print( line )
f.close()

basically i want a shape moving vertically, and when it reaches the upper border of the windows appears in the bottom border.
this is what i have:
from utalcanvas import *
import time
show()
window_size(500,500)
window_style( "Mi Ventana", "black")
window_coordinates(0,0,1000,1000)
circulo = create_filled_circle(500,20,50,"green")
for x in range(100):
y = 10
x = 0
time.sleep(0.0150)
move(circulo, -x, y)
window_update()
any ideas??
thanks! |
Curve fitting is not always that straightforward. The curve_fit algorithm is based on least squares curve fitting and usually needs an initial guess for the input parameters. Depending on the kind of function you want to fit, your initial guess has to be a good one.
Even though you tried an initial guess, I would say you have an additional problem which has to do with your sampling frequency and the frequency of your wave. For further information, you can have a look at the Nyquist-Shannon sampling theorem at Wikipedia. In simple words, the frequency of your wave is 1.759 / (2 * pi) = 0.28, which it turns out to be very close to the sampling frequency of your x array (~0.33). Another issue that might arise is to have too many oscillations to fit to your function.
In order for your code to work, I would either suggest you increase the frequency of your wave (a > 4 * 0.33) or you increase your sampling frequency and reduce the length of your space vector x.
I ran the following code and obtained the results as illustrated here:
# -*- coding: utf-8 -*-
import numpy as np
import pylab as pl
from scipy.optimize import curve_fit
def mysine(x, a):
return 1. * np.sin(a * x)
a = 1.759 # Wave frequency
x = np.linspace(0, 10, 100) # <== This is what I changed
y = np.sin(a * x) + 0. * np.random.normal(size=len(x))
# Runs curve fitting with initial guess.
popt, pcov = curve_fit(mysine, x, y, p0=[1.5])
# Calculates the fitted curve
yf = mysine(x, *popt)
# Plots results for comparison.
pl.ion()
pl.close('all')
fig = pl.figure()
ax = fig.add_subplot(111)
ax.plot(x, y, '-', c=[0.5, 0.5, 0.5])
ax.plot(x, yf, 'k-', linewidth=2.0)
ax.text(0.97, 0.97, ur'a=%.4f, ã=%.4f' % (a, popt[0]), ha='right', va='top',
fontsize=14, transform=ax.transAxes)
fig.savefig('stow_curve_fit.png')

How do I do that? I'm trying NotesAdministrationProcess but some lack example in the help file. Searching the web is difficult since these method is seldom documented. Currently I'm using RenameNotesUser to rename the user but the changes only happen when I run 'tell adminp process new' on the server. How do I automate the the rename after sending the rename request?
Also I've no luck with changing the user's OU/Department. Which method should I use? Currently using RecertifyUser but it pops an error about certifier ID is not an ancestor of something. For example, I want to move a user from Technical department to Sales Department (John/Technical/ACME to John/Sales/ACME). Recertifying John manually in Domino Administrator using the sales ID works fine. I also want the change of user's OU to take effect immediately without telling Domino Console to process it.
The above 2 process don't have to run at the same time because a user couldn't have name and OU change at the same time. Below is the test code/agent that I use (I'll comment the rename code if I want to run the recertify code and vice versa):
Dim s As New NotesSession
Dim db As NotesDatabase
Dim vw As NotesView, doc As NotesDocument
Dim adminp As NotesAdministrationProcess
Dim svr$, path$, cert$, pwd$, staffid$, newlastname$
svr="" 'server1/ACME
path="" 'names.nsf
cert="" 'for rename(C:\tech.id), for recertify(C:\sales.id)
pwd="" 'for rename(tech), for recertify(sales)
staffid="" 'A0001(John's ID)
newlastname="" 'James
Set db=s.Getdatabase(svr, path, False)
Set adminp=s.Createadministrationprocess(svr)
adminp.Certifierfile=cert
adminp.Certifierpassword=pwd
Set vw=db.Getview("People\by Staff Number")
Set doc=vw.Getdocumentbykey(staffid, True)
'for rename. our company only use the last name as name
Call adminp.Renamenotesuser(doc.FullName(0), newlastname)
'for change ou
Call adminp.Recertifyuser(doc.FullName(0))

pyxshell (à prononcer comme vous pouvez) est un module Python qui permet d’enchaîner des fonctions de traitement de flux avec un opérateur « tube » — pipe, en anglais — (|) , de la même manière qu’avec un shell.
Si — comme moi — vous devez régulièrement analyser à la main des données textuelles diversement structurées sous différents environnements. Si vous affectionnez la ligne de commande sans raffoler de la syntaxe de Bash, vous apprécierez d’avoir tout sous la main à côté de vos outils Python favoris.
Par exemple :
>>> out=[]
>>> (random.randint(0,2) for i in range(10)) | map(lambda x: ["Oui ","nous sommes ","tous différents "][x]) | sort | uniq | tee(sys.stdout) > out
Oui tous différents nous sommes
>>> print(out)
['Oui ', 'tous différents ', 'nous sommes ']
Dit autrement, pyxshell permet d’appeler séquentiellement des générateurs sur des structures de données itérables avec une notation infixée. Il descend du ciel avec un ensemble de fonctions qui rappellent celles de la pile GNU, principalement pour traiter des versets textuels ligne par ligne.
Le module permet une redirection des flux vers des fichiers et/ou des variables à l’aide des vénérables opérateurs > et >>. Il permet également d’étendre l’utilisation des tubes à vos glorieuses fonctions, à l’aide d’un décorateur consacré : @pipe. Il dispose en sus d’augustes opérateurs permettant de combiner des flux (avec +) ou d’en faire le produit cartésien de leurs bienheureux éléments (avec *).
pyxshell vous est révélé sous la « (Un)license ».
D’autres exemples tirés des écritures :
>>> import sys
>>> from pyxshell.common import *
>>> list( ['Vous', 'êtes', 'tous','des','individus'] | grep(r'[aeo]') )
['Vous', 'êtes', 'tous', 'des']
>>> ["Je dis que vous êtes le Messie","Et je m'y connais","J'en ai suivi un paquet"] | map(lambda x: "— "+x+"\n") | grep("'") | cut([-2,-1]) | traverse | glue > sys.stdout
m'y connais un paquet
Pour les mécréants qui voudraient utiliser leurs commandes shell de la même façon, depuis un interpréteur, mais sans avoir à utiliser des ré‐implémentations en pur Python, le module Plumbum leur conviendra mieux. |

Re : Conky Control (Live Voyager)
J'ai pu en lancer quelques'uns du coup, mais il y en a qui ne fonctionne pas et surtout quand je ferme le dossier du .scripts, quel que soit le conky lancé, il disparait.
Pour le faire revenir, obligé de faire un kill all conky puis de relancer le conky via le script.

Re : Conky Control (Live Voyager)
Bonjour,
et tout d'abord merci à vous qui nous permettez d'avoir un système et des outils des plus intéressants.
Je teste la 13.10 de Voyager sur un nouveau PC (mais j'ai toujours ma vieille bécane).
J'ai dû un peu trop "personnaliser" mon compte, car ConkyControl qui fonctionnait au début
par le menu contextuel du bureau, est sans effet maintenant.
Si je lance la commande python3 ConkyControl.py dans un terminal
voici ce que j'obtiens :
└─ $ ▶ cd ~/.scripts/Conky/
└─ $ ▶ python3 ConkyControl.py
Conky contrôle Version 1.5
Traceback (most recent call last):
File "ConkyControl.py", line 544, in <module>
app = application()
File "ConkyControl.py", line 532, in __init__
mBar = MenuBar(self)
File "ConkyControl.py", line 140, in __init__
self.BasesConky, self.ConkyLances, self.TempLat = fonctions.initialisation(fonctions())
File "ConkyControl.py", line 72, in initialisation
Latence=findall('-?\d+', line)[0]
IndexError: list index out of range
Je n'ai pas modifié le contenu de ConkyControl.py mais j'ai supprimé des fonctionnalités comme
les bureaux multiples (4 espaces de travail c'est 3 de trop pour moi),
une sorte de tableau de bord sur le côté droit de l'écran, et peut-être d'autres choses encore.
Si vous avez une idée sur le pourquoi du comment, je le promets, je ne recommencerai plus.
D'avance merci.
Alain

EDIT : 14 h 23
Bon, finalement je sais pourquoi, et peut-être comment...
Après avoir examiné les fichiers modifiés depuis l'installation,
j'ai trouvé cette différence, d'un profil à l'autre, dans le fichier DemConky.sh
Dans le profil où ça fonctionne :
#!/bin/bash
# License GPL
sleep 10;
sh -c "conky -c ~/.conky/conky-extra/conky12/conkyrc &"
Dans le profil où une erreur est générée :
#!/bin/bash
# License GPL
sleep None;
sh -c "conky -c ~/.conky/conky-extra/conky12/conkyrc &"
D'où sort ce(tte) None ?
Je n'ai pas (directement en tout cas) modifié ce fichier.
Sans doute une manip involontaire de l'utilisateur (oui, c'est moi )
dans l'interface de réglages, pas prévue au programme et indigeste.
Désolé pour le dérangement, mais cette expérience pourra peut-être servir à d'autres.
Encore merci.

Re : Conky Control (Live Voyager)
Bonjour Didier,
Oui une petite question pour conky control, c'est possible de mettre une fonction icon dans Réglage aspect fenêtres dans yad c'est --window-icon=.... J'ai pas trouvé comment faire pour python ou si c'est possible encore merci. Tu vois je refais tout les styles, avec yad et wall je peux intégrer une miniature icon témoin mais pas pour conky control qui prend une standard. Sinon, pour les options j'ai fait un mélange français anglais comme avec démarrage auto couplé à Autostart, terminer avec finish etc car les étrangers comprennent pas toujours les options.
Sinon, ton Conky control en python toujours au top pour la voyager 14.04. A bientôt et merci

Re : Conky Control (Live Voyager)
bonsoir kennyzz69,
Pour ConkyControl, voici la dernière version.
Il faut décompresser dans ton Home.
Ça ajoutera deux répertoires cacher, Conky et Scripts.
Dans Scripts, tu trouveras le sous-répertoire Conky.
Et dans le répertoire conky, c'est le fichier lanceur qui t’intéresse.
J'ai ajouter la derniere version des conky dans Ubuntu 14.04 j'ai suivi la manip ca ne fonctionne pas
Merci d'avance
je sais pas si ca peux servire je poste le retour de cette commande

Re : Conky Control (Live Voyager)
Bonsoir loulou54,
je crois qu'il y a un soucis dans l'installation faite sur voyager.
Le plus simple est de suivre ma signature, y récupérer le pack de base.
Supprimer les répertoires
~/.conky/conky-meteo/meteo
~/.conky/conky-meteo/meteo_lua_2
Puis installer le débian, tu auras une nouvelle application installer dans accessoires (meteo-lua), elle te permettra de choisir ta ville.
Ensuite il n'y auras plus qu'a lancer le conky.

Re : Conky Control (Live Voyager)
Bonjour loulou54,
C'est tout simple, t'inquiète pas, Didier-T nous as fait un outil "clef en main".
le tilde(~) ça correspond à ton dossier utilisateur. Tu le retrouveras régulièrement dans les lignes de commande ou sur le forum pour désigner ce dossier.
Soit tu les supprimes en graphique en faisant la combinaison des touches Ctrl+H pour faire apparaître les fichiers/dossiers cachés et tu fais comme tu le faisais sous ton ancien système.
Soit tu te contente de recopier les 2 lignes ci-dessous dans un terminal:
rm -r ~/.conky/conky-meteo/meteo
rm -r ~/.conky/conky-meteo/meteo_lua_2
encore moins installer le debian
Il te suffit de double-cliquer dessus et il te proposera de l'installer. Ensuite tu lances meteo-lua et tu renseignes ta ville.
Il ne te reste plus qu'à lancer le conky avec la commande
conky -c ~/.conky/conky-meteo/meteo/conkyrc
ou le plus simple, tu l'ajoutes dans conky control. N'oublie pas ensuite d'enregistrer dans conky control pour qu'il soit présent au redémarrage de la machine.

Le raccourci ctrl H non plus va comprendre ..... ( peut être à cause de voyager 14.04....)
Je ne trouvais pas le dossier conky en fait si mais sans le dossier meteo et pas dans arborescence direct
Donc du coup je me suis dis : on me dis d'installer un debian ( donc un programme on va dire ) si ça se trouve il va tous me recaler

Shortly after I wrote my news article on the Python wiki program MoinMoin, Jürgen Hermann announced a new version with this notice:
This is a security update, which explains the short release cycle. It replaces someexec()calls by__import__(), which is much safer (or actually, safe in contrast to totally unsafe). IF YOU HAVE INSTALLED RELEASE 0.5 OR 0.6, UPGRADE NOW!
Because of the short release cycle, the code couldn't be very different between 0.6 and 0.7. That would make changes easy to spot. I love learning opportunities. I got a copy of 0.6 to compare with 0.7. There are several places in MoinMoin where Hermann wanted to use the same code but choose between different libraries of functions to be used by that code. This is called a plug-in. Hermann uses plug-ins to select formatters based on mime-type, or to select a particular parser or extension macro set based on the type of information submitted from a form. The name of the plug-in module to use is taken from information passed by CGI.
For example, here is the code used to import a formatter:
exec("from formatter.%s import Formatter" %
(string.replace(mimetype, '/', '_'),))
However, mimetype is taken from information passed to the program from an untrustworthy outside source. This may not seem like a big security leak, but any leak is a dangerous thing. Someone could monkey with the string passed to mimetype. The exec function will execute whatever code is passed to it. Using exec, you might unwittingly execute a dangerous block of code. Here is how Hermann fixed it. He replaced these exec strings with this utility function
def importName(modulename, name):
""" Import a named object from a module in the context of this function,
i.e. use fully qualified module paths.
Return None on failure.
"""
try:
module = __import__(modulename, globals(), locals(), [name])
except ImportError:
return None
return vars(module)[name]
The __import__ function only imports the specified code. If the mimetype (passed to this function as modulename) were manipulated now, you would only get an import error, not a surprise intruder.
It's errors like these that the taint mode in Perl was designed to catch. In this paranoid mode, information received from outside the program, like the string assigned to mimetype in this case, is rejected as tainted unless it is first checked by a regular expression. It throws in an extra step designed to make you stop and think before leaving the barn door open.
While Python doesn't have an equivalent to taint mode, it does have a module to help you restrict what might be dangerous code, the restricted execution or RExec module. The RExec module is not needed in this instance because Hermann only needs to import installed code, not evaluate user supplied code. For this purpose, the __import__ function does nicely. If, however, you work with a lot of CGI, you should study up on RExec.

problème wifi avec portable HP nx6125...
Salut à tous, je viens d'installer sans trop de mal Kubuntu 7.10 sur mon portable HP Compaq nx6125 (j'ai de la chance il n'est pas tatoué...). Aparemment tout marche sur la machine... sauf le wifi... j'en ai pas besoin là maintenant mais j'en aurai sûrement besoin et de toutes façons, c'est agréable que tout fonctionne. La carte est fonctionnelle puisqu'aucun problème sous windows, mais rien à faire pour la faire marcher sous Kubuntu. J'ai suivi le tuto http://doc.ubuntu-fr.org/materiel/liste … paq_nx6125 mais rien n'y fait. Voici ce que j'obtiens avec les commandes indiquées sur le sujet épinglé.

On télecharge le driver adequat (bcmwl5):
cd
wget http://dlsvr03.asus.com/pub/ASUS/wireless/WL-100g-03/Driverv3100640.zip
unzip Driverv3100640.zip
Ensuite on installe ndiswrapper:
sudo apt-get install ndiswrapper-utils-1.9
on charge le driver dans ndiswrapper
sudo ndiswrapper -i ~/Driver/WinXP/bcmwl5.inf
et on verifie s'il est bien chargé (avant de faire quoi que ce soi d'autres)
ndiswrapper -l #C'est un petit L
si il affiche un truc qui ressemble à ça:
bcmwl5 : driver installed
device (14E4:4318) present (alternate driver: bcm43xx)
Tu peux continuer!
pour décharger le module chargé automatiquement par Gutsy
sudo rmmod bcm43xx
pour charger ndiswrapper
sudo ndiswrapper -m
sudo modprobe ndiswrapper
Blacklister le module chargé automatiquement par gutsy
echo 'blacklist bcm43xx' | sudo tee -a /etc/modprobe.d/blacklist
Mettre ndiswrapper dans la liste des modules chargés au démarrage:
echo 'ndiswrapper' | sudo tee -a /etc/modules
modif du fichier interfaces
echo -e 'auto lo\niface lo inet loopback\n' | sudo tee /etc/network/interfaces
et connecte toi avec network-manager (2 tv en haut a droite à coté de l'heure)!

Re : problème wifi avec portable HP nx6125...
§Mince j'avais pas vu tu es en 64 bits donc c'est mort pour ndiswrapper, dommage c'est la meilleur soluce!
il faut passer par les driver proprio et donc virer bcm43xx du fichier blacklist:
sudo gedit /etc/modprobe.d/blacklist
et vire toutes les lignes avec
blacklist bcm43xx
ensuite va dans le menu
Système > Administration > Gestionnaire de pilotes propriétaires
et tu coches le pilotes de ta carte (il faut quand même un connection ethernet!)
si ça marche pas passe en 32 bits (le 64 bits c'est pas du tout au point et pas que sous linux il faut attendre quelque années avant de prendre cette solution!)

Re : problème wifi avec portable HP nx6125...
Ah zut... bon, donc il va sans doute que je refasse une install en 32 bits? bon, c'est con mais tant pis, moi qui avait réussi à configurer mon système... 32 bits est sans doute plus stable de toutes façons. En attendant, j'ai essayé d'activer le pilote du modem mais le message est le suivant: "les sources logicielles pour le paquet sl-modem-daemon ne sont pas activées"
O๠puis-je trouver ces sources pour les activer?

Re : problème wifi avec portable HP nx6125...
Ben c'est le seul truc qui reste à installer dans les pilotes propriétaires. Donc j'ai supposé que c'était ça mais après quelques recherches, je vois que c'est le modem fax... donc rien à voir avec le wifi...
Je pense donc passer à 32 bits... le téléchargement est d'ailleurs déjà terminé, mais pas de cd vierge à portée de main...
Je pensais que c'était mieux de passer à 64 bits pour tirer parti de toutes les ressources du système, mais si c'est pas encore au point autant rester à 32 bits... :)
Je recommencerai l'install du wifi après, je tiens au courant merci en tout cas pour ton aide.

Re : problème wifi avec portable HP nx6125...
ok salut et a plus sur ce topic au cas ou
Pour le 64 bits il faut avoir du bol avec le matériel sinon c'est la croix et la bannière.
En plus les logiciel ne sont pas encore vraiment porter en 64 bits juste du code 32 bits compiler en 64 bits donc coté optimisation ça sert a rien au mieux 4 a 10 % de mieux!

Re : problème wifi avec portable HP nx6125...
Vu, oui, effectivement, ça ne sert pas encore à grand chose donc, en plus si ça bloque sur certains trucs... je passe donc à 32 bits, on attendra pour me 64 bits... Merci willy78

Re : problème wifi avec portable HP nx6125...
Salut à nouveau,:)
Je suis donc passé à la distribution en 32bits et j'ai refait les manip pour le carte wifi. Aucune erreur n'apparait, je peux maintenant allumer et éteindre le bouton du wifi sur le portable... auparavant, celui-ci restait allumé ou éteint sans changement...
Par contre le wifi ne marche pas mieux... l'onglet Network dans KNetwork Manager n'est toujours pas activé.
Ai-je raté quelque chose?

Blacklister le module chargé automatiquement par gutsy
echo 'blacklist bcm43xx' | sudo tee -a /etc/modprobe.d/blacklist
Mettre ndiswrapper dans la liste des modules chargés au démarrage:
echo 'ndiswrapper' | sudo tee -a /etc/modules
modif du fichier interfaces
echo -e 'auto lo\niface lo inet loopback\n' | sudo tee /etc/network/interfaces
et connecte toi avec network-manager (2 tv en haut a droite à coté de l'heure)!

Re : problème wifi avec portable HP nx6125...
Salut, oui, tout a été fait.
En fait je crois avoir fait une bourde... j'ai installé bêtement wilan, ce qui apparemment a désinstallé knetwormanager... j'ai desintallé à nouveau wilan et réinstallé knetworkmanager... il est donc installé, j'ai activé eth1, qui correspond à la wifi... donc quand j'ouvre maintenant knetworkmanager ben plus aucun onglet est actif à par le premier... alors qu'avant tous étaient actifs sauf celui de la wifi... Dans Device il me met: No active device... uhmmm, pas facile.

En fait si je comprends bien, les différentes "Cell", c'est les différents réseaux wifi qu'il y a dans le coin?? ma live box en tout cas est bien détectée.
Ou bien alors il faut faire une manip avec la livebox?

Par "activer eth1" c'est dans knetwork manager, configuration manuelle, interfaces réseaux. eth1 était desactivé, donc je me suis imaginé que ça pouvait pas marcher comme ça... j'ai donc activé l'interface mais sans plus de résultats.

Re : problème wifi avec portable HP nx6125...
c'est exactement ce qu'il ne faut pas faire (ne pas utiliser configuration manuel)
C'est incompatible avec knetworkmanager le fichier /etc/network/interfaces ne doit comporter que ça:
auto lo
iface lo inet loopback
La configuration manuel écrit des données dans ce fichier et donc knetworkmanager ne peux plus gérer la connection!
bound to 192.168.1.10 -- renewal in 249034 seconds.
Ceci veut dire que tu es connecter! mais en manuel donc ça marche
cette commande:
echo -e 'auto lo\niface lo inet loopback\n' | sudo tee /etc/network/interfaces
rétabli ce qu'il faut dans le fichier interfaces
après cette commande, attends 1 mn, ensuite tu cliques gauche sur knetworkmanager (sous kde, je crois qu'il est en bas a droite a coté de l'heure) et tu cliques sur ton reseau qui devrais apparaitre!

I can't get a basic shader program working in PyQt. I think this should at least compile the shader code correctly (I'm no expert here), but addShaderFromSourceFile() always returns false no matter what I try. The shader program log is always empty too.

Dernière news : Fedora-Fr aux 15èmes Rencontres Mondiales du Logiciel Libre
Bonjour,
certains savaient que nous travaillions sur la V5 du site Fedora-Fr depuis un petit moment, une version bêta était même disponible depuis petit moment, c'est à présent la page d'accueil du forums ainsi que le planet qui passe la 5ème.
Quels en sont les nouveautés ?
Nouveau design plus respectueux de la charte du fedoraproject
Version plus sociale vu que vous pouvez aimer Fedora-Fr, le Twitter, nous suivre sur les réseau sociaux, etc...
Techniquement mieux avec eZ Publish 4.4, l'utilisation de CSS Sprites, etc...
Plus de recherche avec l'utilisation d'OpenSearch, rajoutez les moteurs de recherches de Fedora-Fr facilement à votre navigateur
Voila, que dire si ce n'est que c'est un gros gros travail collectif et qu'une page de remerciements sera bientôt disponible afin de remercier tout ceux qui ont contribué à cette V5.
Bravo, beau travail !
Seulement, pour la page d'accueil, serait-ce possible de traduire la bannière concernant la Alpha ?
C'est du SVG, cela se traduit, suffit de cliquer sur l'image pour avoir accès aux sources et modifier les chaines…
Sinon je le redis, c'est un beau travail qui a été réalisé, manque plus que le Wiki pour uniformiser.

J'aime bien le nouveaux style général de fedora-fr, c'est moins austère.
Mais sur la page d'accueil je regrette la disparation des dernières nouvelles des blogs et planet, et la mise en retrait de celles du forum.

il manque le blog planet, c'est un oublie de ma part, je le rajoute de suite.
Je viens aussi de looker le compte Twitter avec la V5.

2 - La bannière de F15 est un peu petite maintenant dans sa version francisée. Pas évident de tout lire.

Youuuuuhhhouuuuuuuuuuuuuu !!! Mon article de la doc est sur la première page !
La consécration...
Non sans déc, je testais la v5 depuis le début et elle me plaisait bien au niveau du forum ; mais là, la page d'accueil envoie vraiment du pâté je dois dire.
Bien joué.

Le top pour les nouvelles peintures. Bravo.
Mais je regrette le fait de ne pas suivre les posts pour l' actu du forum qu'on avait en première page (10 derniers posts).
Cela pour tous ceux qui ont des problèmes à traiter et pour ceux qui veuillent bien justement donner un coup de main en temps (plus ou moins) réel.

I think the main problem here is that the browser settings don't actually affect the navigator.language property that is obtained via javascript.
What they do affect is the HTTP 'Accept-Language' header, but it appears this value is not available through javascript at all. (Probably why @anddoutoi states he can't find a reference for it that doesn't involve server side.)
I have coded a workaround: I've knocked up a google app engine script at http://ajaxhttpheaders.appspot.com that will return you the HTTP request headers via JSONP.
(Note: this is a hack only to be used if you do not have a back end available that can do this for you. In general you should not be making calls to third party hosted javascript files in your pages unless you have a very high level of trust in the host.)
I intend to leave it there in perpetuity so feel free to use it in your code.
Here's some example code (in jQuery) for how you might use it
$.ajax({
url: "http://ajaxhttpheaders.appspot.com",
dataType: 'jsonp',
success: function(headers) {
language = headers['Accept-Language'];
nowDoSomethingWithIt(language);
}
});
Hope someone finds this useful.
Edit: I have written a small jQuery plugin on github that wraps this functionality: https://github.com/dansingerman/jQuery-Browser-Language
Edit 2: As requested here is the code that is running on AppEngine (super trivial really):
class MainPage(webapp.RequestHandler):
def get(self):
headers = self.request.headers
callback = self.request.get('callback')
if callback:
self.response.headers['Content-Type'] = 'application/javascript'
self.response.out.write(callback + "(")
self.response.out.write(headers)
self.response.out.write(")")
else:
self.response.headers['Content-Type'] = 'text/plain'
self.response.out.write("I need a callback=")
application = webapp.WSGIApplication(
[('/', MainPage)],
debug=False)

Un nouveau dépôt officiel pour Ubuntu (logiciels commerciaux)
Un nouveau dépot officiel vient d'ouvrir. Il contient des logiciels commerciaux. Pour l'instant Opéra et Realplayer sont disponibles.
En gros, pour l'installer, il faut:
* Activer les mises a jour de dapper
* Mettre a jour sa dapper :-)
* Via gnome-app-install (disponible dans le menu pour tous les membres du groupe admin), activer l'option pour voir les softs commerciaux
* Installer opera.
Pour ceux utilisant apt-get : Ajouter cette ligne dans /etc/apt/sources.list

Ben c'est ce que j'ai fait mais il ne m'a pas proposé d'installer le paquet realplayer, ni quoi que ce soit qui approche..
sudo apt-get update et upgrade ne donnent rien
Quel est le nom de l'appli ? je tente avec Katapult mais real et realplayer sont introuvables. Je pense qu'il n'est pas installé
C'est pas dramatique mais ça fait six mois que j'ai une vidéo à regarder et j'ai pas pu télécharger ce satané programme sous Windows...

Comment est-ce que l'on peut savoir quels logiciels sont disponibles sur un dépôt ? Là on découvre qu'il y a Opera et Realplayer dedans, mais si ça se trouve il y a autre chose qui m'intéresserait. Il n'y a pas une manière d'avoir la liste des logiciels d'un dépôt ?

La version de realplayer fourni dans ce nouveau depot est la derniere (10.0.7) alors que realplayer fourni dans le multiverse est la 8 (ayant des problèmes de dépendances sous Dapper, qui n'est plus supportée ni mise à jour par realnetworks donc absolument non recommandé sauf eventuellement pour les anciennces versions), enfin il existe aussi le paquet realplay dans le depot plf qui est en version 10.0.6
Pour opera, je ne me suis pas penché sur la question !

Bonjour, quelqu'un pourrait - il m'aider car bisarement je n'arrive pas installer opera...
J'ai bien rajouter le dépôt dans mon source.list. un petit update de tout ça mais que se soit par ligne de commande ou bien par synaptic, opera n'est pas trouvée ...
De plus, en passant par "Application - Ajouter/enlever", je voi bien Opera (après avoir cocher "voir les applications commerciales") mais quand je veux l'instaler on me demander d' "Activer le depôt caconical" ... et quand je dit "Ok" la liste des dépendance se recharge et on me redemande à nouveau d'activer le dépôt ...( ca tourne en rond)
Pour info je suis en Ubuntu 64 bits (noyau K8) mais je n' ai pas lu que les dépôts canonical n'étés disponible que pour platforme i386 ...
Voila si quelqu'un peut m'éclairer merci.

Re : Un nouveau dépôt officiel pour Ubuntu (logiciels commerciaux)
Je ne suis pas sur que les paquets existants pour le moment sur ce depot commercial soit prevu pour le 64bits, je m'explique :
1-Si on parcours le contenu du depot (ex ce repertoire http://archive.canonical.com/pool/main/r/realplay/) on se rend compte qu'il n'existe qu'un seul paquet .deb, et dans le nom du paquet, on a un joli *i386.deb et pas de amd64 en vue
2-Ce depot contient bien l'arborescence necessaire pour contenir des paquets destinés à l'architecture amd64 (http://archive.canonical.com/dists/dapper-commercial/main/binary-amd64/) MAIS le contenu du fichier Packages.gz est vide alors que ce meme fichier pour le 32bits contient nos deux paquets du dépots...
Bref, je ne sais pas si j'ai raison mais a priori, je dirais que c'est normal que ton synaptic ne trouve pas opera sous amd64 et ce n'est pas un probleme de sources.list !! Après peut etre qu'on peut bidouiller pour les installer quand meme sur 64bits....mais la, je ne suis pas au courant !

I'm beginning python and I'm trying to use a two-dimensional list, that I initially fill up with the same variable in every place. I came up with this:
def initialize_twodlist(foo):
twod_list = []
new = []
for i in range (0, 10):
for j in range (0, 10):
new.append(foo)
twod_list.append(new)
new = []
It gives the desired result, but feels like a workaround. Is there an easier/shorter/more elegant way to do this? |
Configuring and Managing WebLogic JDBC
In WebLogic Server, you can configure database connectivity by configuring JDBC data sources and multi data sources and then targeting or deploying the JDBC resources to servers or clusters in your WebLogic domain.
Each data source that you configure contains a pool of database connections that are created when the data source instance is created—when it is deployed or targeted, or at server startup. Applications lookup a data source on the JNDI tree or in the local application context (java:comp/env), depending on how you configure and deploy the object, and then request a database connection. When finished with the connection, the application calls connection.close(), which returns the connection to the connection pool in the data source.
Figure 2-1 shows a data source and a multi data source targeted to a WebLogic Server instance.
For more information about data sources in WebLogic Server, see Configuring JDBC Data Sources.
A multi data source is an abstraction around a data sources that provides load balancing or failover processing between the data sources associated with the multi data source. Multi data sources are bound to the JNDI tree or local application context just like data sources are bound to the JNDI tree. Applications lookup a multi data source on the JNDI tree or in the local application context (java:comp/env) just like they do for data sources, and then request a database connection. The multi data source determines which data source to use to satisfy the request depending on the algorithm selected in the multi data source configuration: load balancing or failover. For more information about multi data sources, see Configuring JDBC Multi Data Sources.
A key to understanding WebLogic JDBC configuration and management is that who creates a JDBC resource or how a JDBC resource is created determines how a resource is deployed and modified. Both WebLogic Administrators and programmers can create JDBC resources:
Table 2-1 lists the JDBC module types and how they can be configured and modified.
WebLogic JDBC configuration is stored in XML documents that conform to the weblogic-jdbc.xsd schema (available at http://www.bea.com/ns/weblogic/91/weblogic-jdbc.xsd). You create and manage JDBC resources either as system modules or as application modules. JDBC application modules are a WebLogic-specific extension of J2EE modules and can be configured either within a J2EE application or as stand-alone modules.
When you create a JDBC resource (data source or multi data source) using the Administration Console or using the WebLogic Scripting Tool (WLST), WebLogic Server creates a JDBC module in the config/jdbc subdirectory of the domain directory, and adds a reference to the module in the domain's config.xml file. The JDBC module conforms to the weblogic-jdbc.xsd schema (available at http://www.bea.com/ns/weblogic/91/weblogic-jdbc.xsd).
JDBC resources that you configure this way are considered system modules. System modules are owned by an Administrator, who can delete, modify, or add similar resources at any time. System modules are globally available for targeting to servers and clusters configured in the domain, and therefore are available to all applications deployed on the same targets and to client applications. System modules are also accessible through JMX as JDBCSystemResourceMBeans.
Data source system modules are included in the domain's config.xml file as a JDBCSystemResource element, which includes the name of the JDBC module file and the list of target servers and clusters on which the module is deployed. Figure 2-2 shows an example of a data source listing in a config.xml file and the module that it maps to.
Similarly, multi data source system modules are included in the domain's config.xml file as a jdbc-system-resource element. The multi data source module includes a data-source-list parameter that maps to the data source modules used by the multi data source. The individual data source modules are also included in the config.xml. Figure 2-3 shows the relationship between elements in the config.xml file and the system modules in the config/jdbc directory.
In this illustration, the config.xml file lists three JDBC modules—one multi data source and the two data sources used by the multi data source, which are also listed within the multi data source module. Your application can look up any of these modules on the JNDI tree and request a database connection. If you look up the multi data source, the multi data source determines which of the other data sources to use to supply the database connection, depending on the data sources in the data-source-list parameter, the order in which the data sources are listed, and the algorithm specified in the algorithm-type parameter. For more information about multi data sources, see Configuring JDBC Multi Data Sources.
JDBC resources can also be managed as application modules, similar to standard J2EE modules. A JDBC application module is simply an XML file that conforms to the weblogic-jdbc.xsd schema and represents a data source or a multi data source.
JDBC modules can be included as part of an Enterprise Application as a packaged module. Packaged modules are bundled with an EAR or exploded EAR directory, and are referenced in all appropriate deployment descriptors, such as the weblogic-application.xml and ejb-jar.xml deployment descriptors. The JDBC module is deployed along with the enterprise application, and can be configured to be available only to the enclosing application or to all applications. Using packaged modules ensures that an application always has access to required resources and simplifies the process of moving the application into new environments. With packaged JDBC modules, you can migrate your application and the required JDBC configuration from environment to environment, such as from a testing environment to a production environment, without opening an EAR file and without extensive manual JDBC reconfiguration.
In contrast to system resource modules, JDBC modules that are packaged with an application are owned by the developer who created and packaged the module, rather than the Administrator who deploys the module. This means that the Administrator has more limited control over packaged modules. When deploying a resource module, an Administrator can change resource properties that were specified in the module, but the Administrator cannot add or delete modules. (As with other J2EE modules, deployment configuration changes for a resource module are stored in a deployment plan for the module, leaving the original module untouched.)
By definition, packaged JDBC modules are included in an enterprise application, and therefore are deployed when you deploy the enterprise application. For more information about deploying applications with packaged JDBC modules, see Deploying Applications to WebLogic Server.
A JDBC application module can also be deployed as a stand-alone resource using the weblogic.Deployer utility or the Administration Console, in which case the resource is typically available to the server or cluster targeted during the deployment process. JDBC resources deployed in this manner are called stand-along modules and can be reconfigured using the Administration Console or a JSR-88 compliant tool, but are unavailable through JMX or WLST.
Stand-alone JDBC modules promote sharing and portability of JDBC resources. You can create a data source configuration and distribute it to other developers. Stand-alone JDBC modules can also be used to move JDBC configuration between domains, such as between the development domain and the staging domain.
For more information about JDBC application modules, see Configuring JDBC Application Modules for Deployment.
For information about deploying stand-alone JDBC modules, see "Deploying JDBC, JMS, WLDF Application Modules."
All WebLogic JDBC module files must end with the -jdbc.xml suffix, such as examples-demo-jdbc.xml. WebLogic Server checks the file name when you deploy the module. If the file does not end in -jdbc.xml, the deployment will fail and the server will not boot.
When you use production redeployment (versioning) to deploy a version of an application that includes a packaged JDBC module, WebLogic Server identifies the data source defined in the JDBC module with a name in the following format:
If transactions in a retiring version of an application time out and the version of the application is then undeployed, you may have to manually resolve any pending or incomplete transactions on the data source in the retired version of the application. After a data source is undeployed (in this case, with the retired version of the application), the WebLogic Server transaction manager cannot recover pending or incomplete transactions.
In support of the modular deployment model for JDBC resources in WebLogic Server 9.1, BEA provides a schema for WebLogic JDBC objects: weblogic-jdbc.xsd. When you create JDBC resource modules (descriptors), the modules must conform to the schema. IDEs and other tools can validate JDBC resource modules based on the schema.
The schema is available at http://www.bea.com/ns/weblogic/91/weblogic-jdbc.xsd.
When you create JDBC resources using the Administration Console or WLST, WebLogic Server creates MBeans (Managed Beans) for each of the resources. You can then access these MBeans using JMX or the WebLogic Scripting Tool (WLST). See Developing Custom Management Utilities with JMX and WebLogic Scripting Tool for more information.
Figure 2-4 shows the hierarchy of the MBeans for JDBC objects in a WebLogic domain.
The JDBCSystemResourceMBean is a container for the JavaBeans created from a data source module. However, all JMX access for a JDBC data source is through the JDBCSystemResourceMBean. You cannot directly access the individual JavaBeans created from the data source module.
WebLogic Server 9.1 JDBC supports JSR-77, which defines the J2EE Management Model. The J2EE Management Model is used for monitoring the runtime state of a J2EE Web application server and its resources. You can access the J2EE Management Model to monitor resources, including the WebLogic JDBC system as a whole, JDBC drivers loaded into memory, and JDBC data sources.
JDBCServiceRuntimeMBean—Which represents the JDBC subsystem and provides methods to access the list of JDBCDriverRuntimeMBeans and JDBCDataSourceRuntimeMBeans currently available in the system.JDBCDriverRuntimeMBean—Which represents a JDBC driver that the server loaded into memory. JDBCDataSourceRuntimeMBeans—Which represents a JDBC data source deployed on a server or cluster.
For more information about using the J2EE management model with WebLogic Server, see Monitoring and Managing with the J2EE Management APIs.

You can target or deploy JDBC resources to a cluster to improve the availability of cluster-hosted applications. For information about JDBC objects in a clustered environment, see "JDBC Connections" in Using WebLogic Server Clusters.
Multi data sources are supported for use in clusters. However, note that multi data sources can only use data sources in the same JVM. Multi data sources cannot use data sources from other cluster members. |

Hello.
Oui, il y a une astuce...
Il faut passer par un script suid.
Modifier ton script en :
#!/bin/ksh
service network-manager start
sleep 600
service network-manager stop
Ensuite, le script doit appartenir à root, mais il faut positionner le bit suid (qui permet de s'attribuer les droits du propriétaire du fichier).
sudo chmod 750 monscript
sudo chmod +s monscript
Voilà ce qui devrait faire l'affaire.
Attention, cela crée une faille de sécurité.
Suis avec attention les instructions de cette page.

Tout d'abord, il y a une erreur dans le script, la première ligne est à supprimer
Ensuite, comme je l'indiquais, mettre le bit SUID sur un script présente trop de failles de sécurité. Cela a été désactivé.
Et puis ksh n'est plus nécessaire (je viens de me rendre compte qu'il n'est pas installé par défaut sous Ubuntu).
En relisant ta demande, je vois que tu acceptes de saisir ton mot de passe admin, il y a donc uns solution simple.
On va créer le script dans /root
(sudo gedit /root/a.sh).
#!/bin/sh
service network-manager start
sleep 600
service network-manager stop
(edit... j'avais oublié)
sudo chmod 700 /root/a.sh
Le script a mettre sur le bureau
#!/bin/sh
gksudo /root/a.sh
Lui mettre les droits d'exécution.
Si tu double-cliques dessus, il devrait te demander les droits d'admin et lancer le script.
(J'ai testé sous XFCE et ça marche avec un script similaire).

Me revoila !
J'ai beaucoup cherché, mais je n'ai pas trouvé de cas similaire, y compris sur les forums anglais.
Je te propose d'essayer encore quelques manips, et si on n'y arrive pas, de tester avec une version de noyau plus anciennes.
Je pense que le problème tourne bien autours de l'activation hardware, et qu'il faudrait essayer de bidouiller autour de ça.
1) Dans le BIOS
Essaye de regarder s'il y a quelque chose qui permette de configurer la touche F12 (soit pour la désactiver, soit pour changer la valeur d'activation par défaut)
Il faut que tu observes les changements éventuels par
rfkill list
qui ne doit pas remonter "Hard blocked"
2) Manœuvrer cette touche et voir (toujours par la commande rfkill) si cela change quelquechose.
3) Essayer de voir si une commande privée du driver permettrait d'activer la wifi (je n'y crois pas trop, mais bon...)
Chez moi cela donne :
nicolas@picogiga:~$ sudo iwpriv wlan0
wlan0 no private ioctls.
Ce qui signifie que je n'ai pas de commandes privées pour le driver. Qu'en est-il chez toi ?
4) Essayer une version backport du noyau
Si tu tapes :
apt-cache search linux|grep image|grep backport
Tu devrais voir apparaître une liste des modules backportés pour la wifi (c'est le cas en 12.04)
Il faudra que tu choisisses une version (ne prends pas le pae, tu es en 64bits), et que tu l'installes par une ligne de commande du genre (à compléter par le résultat de la commande précédente)
sudo apt-get install linux-backports-modules-cw-?.?-raring-generic

2: phy0: Wireless LAN
Soft blocked: no
Hard blocked: no

Hard blocked: no
2: phy0: Wireless LAN
Soft blocked: yes
Hard blocked: no
18: hci0: Bluetooth
Soft blocked: no
Hard blocked: no
root@picogiga:~# rfkill unblock wifi
De même, pour le mode avion ? Il est également parfois résolvable par iwconfig wlan0 txpower on(ici)... mais dans ce cas iwconfig le signale...
Bon, en tout cas pour revenir au problème initial de simbad83, tu peux essayer la commande...
NicoZic56
Réponses : 29
Je crois que c'est bon signe... pour une carte ralink, apparemment, ce n'est wlan0, mais ra0.
Pour mon information, peux-tu confirmer que c'est la commande rfkill qui a créé l'interface ?
D'après ce que j'ai vu ailleurs, cela devrait maintenant marcher... Est-ce la cas ?
Ensuite, il faudrait reposter toutes les commandes du début (que tu as déja postées), ou du moins toutes celles qui ont changées.

Je n'ai pas trouvé ni le patch, ni ce qu'il est censé corriger. Ou l'as-tu trouvé ?
Cela m'inspire 2 remarques :
1) peut-être que le driver 64bits est bugué. Est-ce que cela t'irais d'essayer un noyau pae ?
2) j'ai déjà compilé des drivers pour linux. Si on est sûrs que cela va corriger le problème, donne-moi ton état d'avancement, je pense que je pourrais te dépanner...

Est-ce que la commande rfkill list indique toujours un blocage hardware ?
Si c'est le cas, c'est que malheureusement on n'aurait pas beaucoup avancé.

Bonjour !
Je pense qu'il faut modifier la configuration wifi de ta box.
Je pense qu'elle apparaît dans le scan en premier, et que tu ne diffuses pas le SSID (c'est pour cela qu'elle n'apparaît pas ESSID:"<hidden>")
Il faudrait te connecter sur l'interface d'administration de ta box.
Change le numéro de canal.
Tous les points d'accès a proximité émettent sur le canal 11.
Change donc le canal pour 1, cela devrait beaucoup mieux marcher.
Tu peux aussi cocher diffuser le SSID (ou nom de réseau) cela pourrait simplifier le diagnostic ultérieur.

C'est assez compatible avec le problème de canal réseau que je t'ai soumis. Certaines box ont un choix de canal automatique, mais selon mon expérience, cela ne marche pas toujours très bien. Il a suffit que l'une d'entre elle reboote pour que le problème disparaissent.
Si tu relances une commande sudo iwlist wlan0 scanning tu devrais voir les autres canaux. Si le problème se reproduit, la recommandation de changer le numéro de canal reste valide.

I have a single template that is serviced by multiple view functions. As an example, read_posts() view returns all posts with a GET, add_post() view adds a new post with a POST.
I may have other post actions on the same page, needing more view functions.
Now, each of these view functions need to pass different arguments to the template. E.g. each form might require a different form argument to be passed.
What is the best practice in organizing the multiple arguments to a single template from multiple view functions?
As an example posts.html is the template I use:
<html>
<head>
<title>My Django Blog</title>
</head>
<body>
<form action="{% url 'blog:add_post' %}" method="post">
{% csrf_token %}
<p><input type="text" name="title" id="title" /></p>
<p><input type="textarea" name="text" id="text" /></p>
<input type="submit" value="Submit" />
</form>
{% for post in posts %}
<h1>{{ post.title }}</h1>
<h3>{{ post.pub_date }}</h3>
{{ post.text }}
{% endfor %}
</body>
</html>
Here are the views I use:
def display_posts(request):
#All posts
posts = Post.objects.all()
sorted_posts = posts.order_by('-pub_date')
context = { 'posts' : sorted_posts }
return render(request, 'blog/posts.html', context)
def add_post(request):
if request.method == 'POST':
form = PostForm(request.POST)
#return HttpResponse('Hello World')
if form.is_valid():
post = Post()
post.title = form.cleaned_data['title']
post.text = form.cleaned_data['text']
post.pub_date = datetime.now()
post.save()
return HttpResponseRedirect(reverse('blog:display_posts'))
else:
form = PostForm() # An unbound form
return render(request, "blog:display_posts")
As you may see display_posts() is the default GET when the page is requested, and add_post() handles the http POST, when a new post is created.
Each function is handling a different functionality of the page, and they need different context variables passed to the template. (Note I used context only for display_posts just yet)
How do I make sure each function sends a different context to the page, and I organize them properly in the template?
When you handle multiple forms on a page, do you use partial templates for them and %include them in the main page?
Thanks. |

I'm using Python 3.2.3's urllib.request module to download Google search results, but I'm getting an odd error in that urlopen works with links to Google search results, but not Google Scholar. In this example, I'm searching for "JOHN SMITH". This code successfully prints HTML:

I obtained these links by searching in Chrome and copying the link from there. One commenter reported a 403 error, which I sometimes get as well. I presume this is because Google doesn't support scraping of Scholar. However, changing the User Agent string doesn't fix this or the original problem, since I get URLErrors most of the time. |
« Back to Material for Readers
There are some small errors in our book that we think readers may want to know about. Any code errors listed here have been corrected in the source code downloads.
If you find anything else, please let us know!
Page 66, first code sample: The correct code for Django 1.0 is slightly different. Specifically, you will want to uncomment lines 2, 3 and 14 (and probably 11 as well) in the generated urls.py, so it looks like this:
# Uncomment the next two lines to enable the admin:
from django.contrib import admin
admin.autodiscover()
urlpatterns = patterns('',
# Example:
# (r'^mysite/', include('mysite.foo.urls')),
# Uncomment the admin/doc line below and add 'django.contrib.admindocs'
# to INSTALLED_APPS to enable admin documentation:
(r'^admin/doc/', include('django.contrib.admindocs.urls')),
# Uncomment the next line to enable the admin:
(r'^admin/(.*)', admin.site.root),
)
Page 101, second code sample: Everything below class Meta should be indented one more stop (four spaces).
Page 126, first sentence of third paragraph: HttpRequest should be HttpResponse.
Page 189, 2nd sentence of 3rd paragraph after "Controlling Which Stories Are Viewed" header: says "Custom Managers" section is in Chapter 4. This is incorrect: custom managers are covered in Chapter 11 instead.
Page 192, second code sample: The "cms-search" urlpattern needs to occur before the "cms-story" urlpattern, or else search is never reached.
Page 199, code sample: there should be a Q where the line-wrap marker is printed.
Page 217, Javascript code sample, second-to-last line: remove the double-quote after "update" (but keep the space and the single quote).
Page 222, code sample: In the definition of the timestamp field, replace default=datetime.datetime.now with auto_now_add=True.
Page 224, before form code: Explanation for "seeming redundancy in the path name" was omitted. In short, the reason is: the pastebin app uses generic views that expect certain template naming conventions (they want to find the templates in a directory on our template search path that's named after the app). |
clang
LLVM's clang (at least 3.1) can be easily used via -Dcc=clang.
The benefit is that your generated code will be faster on DEBUGGING (optimized not so far), compile + link times are much faster and use much less memory, the diagnostics are better and because its AST does not simplify the code beyond repair (as with gcc) it is easy to add various code check passes and diagnostics such as ASan.
I found several warnings which I previously ignored in my code.

llvm is llvm-gcc-4.5, which is the slowest, clang is clang 3.1, which is fast , cc is gcc-4.6.1 which is a bit faster -O2
address-sanitizer
And then there is Google's address-sanitizer (ASan), which detects invalid pointer accesses (read+write) to stack, heap and globals. Also via shadow memory maps as Dr.Memory and DynamoRIO, just much faster than any other memory checker. It's only 2x slower than unchecked, compared to 20x slower with valgrind and 10x with drmemory. And it needs much less memory.http://code.google.com/p/address-sanitizer/wiki/AddressSanitizerGoogle checks chromium with it.
-Dcc='~/address-sanitizer/asan_clang_Linux/bin/clang'
-Accflags=-faddress-sanitizer
-Accflags='-mllvm\ -asan-blacklist=asan_blacklist.ignore'
-Aldflags=-faddress-sanitizer
-Doptimize='-g3\ -O1'
So I added such a perl-5.15.5d-nt-asan to my debugging test suite. But I had to create a custom asan_blacklist.ignore list to exclude lots of early asan bugs/limitations (Most of them are now fixed).
Notes:
An existing old clang in your path will harm the build process.
I first couldn't build on Linux, even clean, only on Darwin. -m32 support was missing in my libc. So make lib64 installdid the trick.
Use -Doptimize=-O2 (or use Alex' -O0 patch)
The problem was that current ASan is not yet properly initialized with -O0, so our Configure probes did fail. I patched it but the developers didn't like it, though it worked for me to create a miniperl and with -O0 a perl and most CPAN modules. I just bypassed ASan. You really need -O1 or -O2 to use ASan. Can we persuade Merjin to use -O1 just for ASan? For sure not.
Update: Alex created a better patch to support -O0 and this looks fine now. Great! See issue 11
On one system I got some linker problem with -fstack-protector, so I removed that from makefile and config.sh. We do not want to check that twice anway. On my debian box and my fixed post-configure clang setup it worked ok with -fstack-protector though.
There's still a Darwin init problem somewhere. Even with DYLD_NO_PIE=1I had to force init IO, with something like
DYLD_PRINT_OPTS=1 ./miniperl -Dv -Ilib configpm
to get past initial ctor crashes.
export DYLD_PRINT_OPTS=1 && make
and sometimes even
make MINIPERL="./miniperl -Dv -Ilib"
was needed. Problem was not debuggable as it worked okay from the debugger. My darwin seems to load the wrong malloc hook.
And it eventually it led to the first worthwhile problem to inspect, an invalid write in a threaded miniperl. valgrind did not detect this.
$ ./miniperl -Ilib configpm
Expected a Configure variable header or another paragraph of description at configpm line 1010, <GLOS> chunk 1035.

miniperl+0x42e546 is what? It cannot resolve the syms in the backtrace yet. There is an external tool scripts/asan_symbolize.py, but these should better be rewritten in perl to be more stable. I've written now such a symbolizer tool at https://gist.github.com/1392123 and put the full results to perl514.cpanel.net.
So far I prefer objdump with manual macro expansion. Adding symbolizing to asan would be my wishlist, as it sees the expanded macro also.

So either cur_env.je_buf or cur_env.je_ret is wrong. Now we really have to use the debugger. If we are lucky the error is reproducable within gdb. In my case not. Or if not add a printf to this line.
Recompilation with instructing the linker to use the same flags as cc helped here.I added -g -O2 -faddress-sanitizer to all LDFLAGS in makefile. There are three. perl Configure sucks big time with it's cc driver centrism, ignoring ld.
This time it compiled fine and I found what looks like a real core bug:

Now this really looks like an invalid read past the trailing 0-byte on the gv name. (size 11 of 'List::Util' sounds like the 0 was allocated. 8+2+1 = 11)

These macro expansions are a bit longer, so I spare you the details. Same procedure as above. 0xfe440 is in Perl_gv_init_pvn, which comes from List/Util.so which probably defined the global name of the module.
The bug really was there in ListUtil.xs
if (SvTYPE(rmcgv) != SVt_PVGV)
gv_init(rmcgv, lu_stash, "List::Util", 12, TRUE);
12 is clearly off-by-two. A classical copy&paste error from 3 lines above. What worries me is that no other compiler or tool found this. Filed as rt.cpan.org #72700
And why does valgrind does not complain? Because valgrind cannot find Global OOB (Out of bound) not Stack OOB, only Heap OOB. Here we have the global variable '.str27'.
valgrind only found these known leaks: (full details with --leap-check=full)

An invalid read is certainly more important than a minor leak. And valgrind is so slow that it is only used randomly. ASan is so fast and so much better that I compile it in and use it all the time now in my debugging perl.
BTW, the leak is:

Summary of found perl core bugs
With the old asan rev 144800 I found 32+13 new unique perl core problems, unthreaded. Most of them look security relevant. Just filed one bug report for now. Will have to automate this somehow. scripts/asan_symbolize.py works only on Linux for me, and I wrote a better symbolizer asan_addr2dis. Some of the problems seem to be asan problems not perl.
address-sanitizer: I love you!
There are some minor bugs still, it is currently being merged into llvm proper, but it's usable.

The developer mentions for those OOB reads:
Please be aware that some of the out-of-bound reads may be caused by over-optimizations in string processing functions.For example, a function may read 8 bytes at a time if it knows that the strings are 8-aligned and NULL-terminated. Theoretically this is still an error, but in practice it should not cause any problems.
I have to check all of them manually and keep them in an asan perl blacklist, which is a suppression file.
After some days analyzing mosty of these reports I came to the conclusion that only the very first report caught a perl bug, the rest were false positives. Caused by either not detecting local pointer updates or by mangling the control-flow with longjmp.
Since then asan is now included in llvm trunk, and miniperl can be compiled out of the box. See the asan HowToBuild instructions, and for configure I used
-D'cc=/usr/src/llvm/projects/compiler-rt/lib/asan_clang_linux/bin/clang'
-A'ccflags=-faddress-sanitizer'
-A'ldflags=-faddress-sanitizer'

Static analysis with clang-analyzer
clang comes with scan-build which uses ccc-analyzer to statically analyze C/C++ code. http://clang-analyzer.llvm.org/
scan-build ./Configure ...
scan-build -V -k make
scan-build -V -k make test
generates a lot of html reports in /tmp/scan-build-* Have a look and you will be surprised. It's no big deal mostly, but Perl definitely could benefit from more compiler attributes esp. noreturn, and more defensive code. |
Update (May 2014): Please note that these instructions are outdated. while it is still possible (and in fact easier) to blog with the Notebook, the exact process has changed now that IPython has an official conversion framework. However, Blogger isn't the ideal platform for that (though it can be made to work). If you are interested in using the Notebook as a tool for technical blogging, I recommend looking at Jake van der Plas' Pelican support or Damián Avila's support in Nikola.
Update: made full github repo for blog-as-notebooks, and updated instructions on how to more easily configure everything and use the newest nbconvert for a more streamlined workflow.
Since the notebook was introduced with IPython 0.12, it has proved to be very popular, and we are seeing great adoption of the tool and the underlying file format in research and education. One persistent question we've had since the beginning (even prior to its official release) was whether it would be possible to easily write blog posts using the notebook. The combination of easy editing in markdown with the notebook's ability to contain code, figures and results, makes it an ideal platform for quick authoring of technical documents, so being able to post to a blog is a natural request.
Today, in answering a query about this from a colleague, I decided to try again the status of our conversion pipeline, and I'm happy to report that with a bit of elbow-grease, at least on Blogger things work pretty well!
The purpose of this post is to quickly provide a set of instructions on how I got it to work, and to test things out. Please note: this requires code that isn't quite ready for prime-time and is still under heavy development, so expect some assembly.
Converting your notebook to html with nbconvert
The first thing you will need is our nbconvert tool that converts notebooks across formats. The README file in the repo contains the requirements for nbconvert (basically python-markdown, pandoc, docutils from SVN and pygments).
Once you have nbconvert installed, you can convert your notebook to Blogger-friendly html with:
nbconvert -f blogger-html your_notebook.ipynb
This will leave two files in your computer, one named your_notebook.html and one named your_noteboook_header.html; it might also create a directory called your_notebook_files if needed for ancillary files. The first file will contain the body of your post and can be pasted wholesale into the Blogger editing area. The second file contains the CSS and Javascript material needed for the notebook to display correctly, you should only need to use this once to configure your blogger setup (see below):
# Only one notebook so far
(master)longs[blog]> ls
120907-Blogging with the IPython Notebook.ipynb fig/ old/
# Now run the conversion:
(master)longs[blog]> nbconvert.py -f blogger-html 120907-Blogging\ with\ the\ IPython\ Notebook.ipynb
# This creates the header and html body files
(master)longs[blog]> ls
120907-Blogging with the IPython Notebook_header.html fig/
120907-Blogging with the IPython Notebook.html old/
120907-Blogging with the IPython Notebook.ipynb
Configuring your Blogger blog to accept notebooks
The notebook uses a lot of custom CSS for formatting input and output, as well as Javascript from MathJax to display mathematical notation. You will need all this CSS and the Javascript calls in your blog's configuration for your notebook-based posts to display correctly:
Once authenticated, go to your blog's overview page by clicking on its title.
Click on templates (left column) and customize using the Advanced options.
Scroll down the middle column until you see an "Add CSS" option.
Copy entire the contents of the _headerfile into the CSS box.
That's it, and you shouldn't need to do anything else as long as the CSS we use in the notebooks doesn't drastically change. This customization of your blog needs to be done only once.
While you are at it, I recommend you change the width of your blog so that cells have enough space for clean display; in experimenting I found out that the default template was too narrow to properly display code cells, producing a lot of text wrapping that impaired readability. I ended up using a layout with a single column for all blog contents, putting the blog archive at the bottom. Otherwise, if I kept the right sidebar, code cells got too squished in the post area.
I also had problems using some of the fancier templates available from 'Dynamic Views', in that I could never get inline math to render. But sticking to those from the Simple or 'Picture Window' categories worked fine and they still allow for a lot of customization.
Note: if you change blog templates, Blogger does destroy your custom CSS, so you may need to repeat the above steps in that case.
Adding the actual posts
Now, whenever you want to write a new post as a notebook, simply convert the .ipynb file to blogger-html and copy its entire contents to the clipboard. Then go to the 'raw html' view of the post, remove anything Blogger may have put there by default, and paste. You should also click on the 'options' tab (right hand side) and select both Show HTML literally and Use <br> tag, else your paragraph breaks will look all wrong.
That's it!
What can you put in?
I will now add a few bits of code, plots, math, etc, to show which kinds of content can be put in and work out of the box. These are mostly bits copied from our example notebooks so the actual content doesn't matter, I'm just illustrating the kind of content that works.
# Let's initialize pylab so we can plot later%pylab inline
With pylab loaded, the usual matplotlib operations work
x = linspace(0, 2*pi)plot(x, sin(x), label=r'$\sin(x)$')plot(x, cos(x), 'ro', label=r'$\cos(x)$')title(r'Two familiar functions')legend()
The notebook, thanks to MathJax, has great LaTeX support, so that you can type inline math $(1,\gamma,\ldots, \infty)$ as well as displayed equations:
$$ e^{i \pi}+1=0 $$
but by loading the sympy extension, it's easy showcase math output from Python computations, where we don't type the math expressions in text, and instead the results of code execution are displayed in mathematical format:
%load_ext sympyprintingimport sympy as symfrom sympy import *x, y, z = sym.symbols("x y z")
From simple algebraic expressions
Rational(3,2)*pi + exp(I*x) / (x**2 + y)eq = ((x+y)**2 * (x+1))eqexpand(eq)
To calculus
diff(cos(x**2)**2 / (1+x), x)
You can easily include formatted text and code with markdown
You can italicize, boldface
build
lists
and embed code meant for illustration instead of execution in Python:
def f(x):
"""a docstring"""
return x**2
or other languages:
if (i=0; i<n; i++) {
printf("hello %d\n", i);
x += 4;
}
And since the notebook can store displayed images in the file itself, you can show images which will be embedded in your post:
from IPython.display import ImageImage(filename='fig/img_4926.jpg')
You can embed YouTube videos using the IPython object, this is my recent talk at SciPy'12 about IPython:
from IPython.display import YouTubeVideoYouTubeVideo('iwVvqwLDsJo')
Including code examples from other languages
Using our various script cell magics, it's easy to include code in a variety of other languages
%%rubyputs "Hello from Ruby #{RUBY_VERSION}"%%bashecho "hello from $BASH"
And tools like the Octave and R magics let you interface with entire computational systems directly from the notebook; this is the Octave magic for which our example notebook contains more details:
%load_ext octavemagic%%octave -s 500,500# butterworth filter, order 2, cutoff pi/2 radiansb = [0.292893218813452 0.585786437626905 0.292893218813452];a = [1 0 0.171572875253810];freqz(b, a, 32);
The rmagic extension does a similar job, letting you call R directly from the notebook, passing variables back and forth between Python and R.
%load_ext rmagic
Start by creating some data in Python
X = np.array([0,1,2,3,4])Y = np.array([3,5,4,6,7])
Which can then be manipulated in R, with results available back in Python (in XYcoef):
%%R -i X,Y -o XYcoefXYlm = lm(Y~X)XYcoef = coef(XYlm)print(summary(XYlm))par(mfrow=c(2,2))plot(XYlm)XYcoef
And finally, in the same spirit, the cython magic extension lets you call Cython code directly from the notebook:
%load_ext cythonmagic%%cython -lmfrom libc.math cimport sinprint 'sin(1)=', sin(1)
Keep in mind, this is still experimental code!
Hopefully this post shows that the system is already useful to communicate technical content in blog form with a minimal amount of effort. But please note that we're still in heavy development of many of these features, so things are susceptible to changing in the near future. By all means join the IPython dev mailing list if you'd like to participate and help us make IPython a better tool! |

Re : [python]Monsieur Cinéscript

T'façon, c'est moi le graphiste.
En admettant qu'on ai un serveur dispo, Y aurait moyen de faire tourner un javascript qui permettrai de savoir si un film a déjà été joué ?
C'est un peu hard, pour le moment, le seul truc que j'ai trouvé, c'est de faire une recherche dans la page avec le numéro IMDB.

Re : [python]Monsieur Cinéscript
tout est possible, mais je ne vois pas de différence entre
- "Ctrl+F" et entrer le nom du film (ou son numéro)
- "clique sur l'appli java" et entrer le nom du film (ou son numéro)
la recherche textuelle est intégrée dans tous les navigateurs, on ferait quoi de plus ?
Sinon, pour le serveur, j'ai une question :
si on automatise tout, on risque d'avoir des trucs comme ça
[*]tt0125451[/*] planqué un peu partout
ou des balises fausses à cause d'une erreur de frappe, et personne ne le remarquerait.
Bon, pour l'instant on a system qui dit oui à des titres "(DVD release)", cpas mieux
Mais autant changer pour le meilleur. Vous verriez comment les choses ?

Re : [python]Monsieur Cinéscript
Salut,
Je suis développeur Python à mes heures perdues. Je me permets de faire quelques remarques sur le style. En Python, on aime développer de façon "pythonne", on aime le style.
try/except :
Même si Python le permet, toujours mettre la classe de l'erreur après un except
try :
tid = url.split('=')[1].rstrip('&p')
except :
tid = 'ERROR : url invalide ?'
est à éviter.
Il est préférable qu'une exception qui n'est pas anticipée fasse tout simplement planter le programme.
opérateur ternaire :
Plutôt que :
if new_imdb :
imdb_str = ' '.join(new_imdb)
else :
imdb_str = ''
préfère
imdb_str = ' '.join(new_imdb) if new_imdb else '';
ou (ancien style) :
imdb_str = new_imdb and ' '.join(new_imdb) or '';
Ça ne laisse pas de doute sur l'alimentation de la variable, et c'est plus concis.
Fichiers :
Plutôt que :
file = open('tchernia', 'r')
tchernia = file.readlines()
file.close()
penche toi sur l'utilisation du mot clef 'with'. Tu verras que c'est plus sûr, et plus joli !
Fonctions lambda :
Plus concis également et très Python-style, tu peux remplacer :
def cleanString(s):
if isinstance(s,str):
s = unicode(s,"utf-8","replace")
s=unicodedata.normalize('NFD',s)
return s
par :
cleanString = lambda s: unicode(s,"utf-8","replace") if isinstance(s,str) else unicodedata.normalize('NFD',s)
mais c'est du détail... (et toujours préférer la lisibilité)
Tuples et variables :
On aime bien en python utiliser le dépaquetage de tuples pour alimenter les variables. Par exemple, au lieu de
a = a.lstrip()
b = b.lstrip()
On peut écrire :
a, b = a.lstrip(), b.lstrip()
Toujours plus simple :
Plutôt que :
liste_alpha = []
for i in range(28) :
liste_alpha.append([])
Préfère xrange que range si c'est pour une boucle (xrange retourne un itérateur. range une liste, et donc plus d'espace mémoire).
'i' est ici une variable inutilisée. En python on a coutume de nommer ce genre de variable '_'.
Ce qui donne :
liste_alpha = []
for _ in xrange(28) :
liste_alpha.append([])
Mais dans ce cas précis tu peux faire encore plus simple :
liste_alpha = 28*[[]]
Voila pour mes deux centimes. Plus d'infos sur le style Python ici : PEP 8
Tu ne perds pas ton temps à apprendre Python

Re : [python]Monsieur Cinéscript
salamat loutre !
merci pour tes retours !
try/except :
Même si Python le permet, toujours mettre la classe de l'erreur après un except
yep, c'est pas propre, j'ai dealé au fur et à mesure des bugs
préfère
imdb_str = ' '.join(new_imdb) if new_imdb else '';
ou (ancien style) :
imdb_str = new_imdb and ' '.join(new_imdb) or '';
Ça ne laisse pas de doute sur l'alimentation de la variable, et c'est plus concis.
hmmm, je vois l'intérêt, mais par goût perso je n'aime pas les "if else" sur la même ligne.
C'est comme pour les fonctions que les vrais "pythonneux" affectionnent. C'est bine concis mais ce n'est plus lisible pour moi, il faut encore que je m'habitue aux lamda...
penche toi sur l'utilisation du mot clef 'with'. Tu verras que c'est plus sûr, et plus joli !
oui, je ne connaissais pas quand j'ai commencé à coder, c'est bien de me rappeler que je devrais améliorer les choses maintenant que je connais un peu plus (idem pour les tuples)
ok pour xrange et la dénomination de i, c'est bon à savoir.
mais :
liste_alpha = 28*[[]]
ne fonctionnait pas avec le reste.
Je me souviens l'avoir tester dans tous les sens (en python2.6, je ne sais pas si ça joue)
en tous cas je n'arrivais pas à balancer
alfab = 'abcdefghijklmnopqrstuvwxyz'
for i in dicfilm.items():
if i[1] in alfab :
liste_alpha[alfab.index(i[1])+1].append(i[0])
elif i[1].isdigit() :
liste_alpha[0].append(i[0])
else :
liste_alpha[27].append(i[0])

correction manuelle pour le doublon "Le locataire" et le classement de "L'homme qui aimait les femmes"
Ça me fait penser, je peux assez facilement passer un script sur la liste entière pour faire un tri alphabétique cohérent, dont on conserverait le principe pour la suite des mise à jour.
Le problème est le "principe" en lui-même : qu'est-ce que l'on considère comme le premier mot ? (on vire tous les déterminants ? autre idée ?)

I have an object subclass which implements a dynamic dispatch __ iter __ using a caching generator (I also have a method for invalidating the iter cache) like so:
def __iter__(self):
print("iter called")
if self.__iter_cache is None:
iter_seen = {}
iter_cache = []
for name in self.__slots:
value = self.__slots[name]
iter_seen[name] = True
item = (name, value)
iter_cache.append(item)
yield item
for d in self.__dc_list:
for name, value in iter(d):
if name not in iter_seen:
iter_seen[name] = True
item = (name, value)
iter_cache.append(item)
yield item
self.__iter_cache = iter_cache
else:
print("iter cache hit")
for item in self.__iter_cache:
yield item
It seems to be working... Are there any gotchas I may not be aware of? Am I doing something ridiculous? |
I would like to iterate in a for loop using 3 (or any number of) lists with any number of elements, for example:
from itertools import izip
for x in izip(["AAA", "BBB", "CCC"], ["M", "Q", "S", "K", "B"], ["00:00", "01:00", "02:00", "03:00"]):
print x
but it gives me:
('AAA', 'M', '00:00')('BBB', 'Q', '01:00')('CCC', 'S', '02:00')
I want:
('AAA', 'M', '00:00')('AAA', 'M', '01:00')('AAA', 'M', '02:00')..('CCC', 'B', '03:00')
Actually I want this:
for word, letter, hours in [cartesian product of 3 lists above]
if myfunction(word,letter,hours):
var_word_letter_hours += 1

If I want to move to C++ and SDL in the future, is Python and pygame a good way to learn SDL?
Python+PyGame is a really great idea for learning SDL.
I wrote a somewhat popular game that way. Python/PyGame seems much more advanced than SDL bindings to any other language, and one huge advantage compared to C++ is that don't have to compile code, and with some simple hacking can even modify a running program, and see the feedback live. It makes a huge huge difference - like using a GUI vector graphics program vs writing SVG in a text editor. Unfortunately you don't get this out of the box, because you need to adapt your program a bit to see it.
As for other advantages of PyGame, jrpg ran with very small changes on Linux, Windows, and OSX. I had to do some tweaks to fullscreen mode switching, and double buffering as there were some differences between OSes, but no recompilation was ever necessary. If you have any problems you can get good stack trace and debug your problems live, that's not really possible with C++ once you get a memory corruption or a segfault.
I don't really know how easy or how hard would it be to mix C++ and Python for your SDL games. I think it cannot be too hard, as PyGame is a pretty straightforward but very nicely made wrapper for SDL, and Python/C++ mixing is supposed to be easy enough.
You can learn some techniques, ways to implement game logic etc. in SDL-based enviroment but after moving to C++/SDL you will have to use SDL functions directly, helper functions/objects from pyGame will be completely useles.
pygame abstracts the SDL interface quite a lot, therefore I don't think there's much of an advantage carried over.
Of course. You can write a sdl game or tools in really less time.
You can start with this code that display the data/chimp.bmp into a 468x60 screen :
import pygame, sys,os
from pygame.locals import *
pygame.init()
window = pygame.display.set_mode((468, 60))
pygame.display.set_caption('Monkey Fever')
screen = pygame.display.get_surface()
monkey_head_file_name = os.path.join("data","chimp.bmp")
monkey_surface = pygame.image.load(monkey_head_file_name)
screen.blit(monkey_surface, (0,0))
pygame.display.flip()
def input(events):
for event in events:
if event.type == QUIT:
sys.exit(0)
else:
print event
while True:
input(pygame.event.get())
When you are familiar with SDL objects you can easily move to C++ (if you want again :p Pygame is fast and you can make a complexe game with it).
You could try pyglet If you are targetting at OpenGL. It's much better thought out library than what pygame is.
But then, if you want to move to C++ and SDL in future, do it now. That way you actually learn SDL. But before doing such an irresponsible thing, it'd be perhaps a good idea to check into pyglet first.

python won't prevent you off learning
For your purpose PySDL2 is better than pygame. It imports SDL2 API almost directly.
I wouldn't consider Python (or any managed or interpreted language, for that matter) a good way to learn any complex task, because it insulates the programmer from the workings of the system too much. As a friend of mine put it, "Python loves you and wants you to be happy." And that's all well and good if you already know the fundamentals, but if you want to
You'll learn the what very quickly, but not the why, and then when something goes badly wrong, (and it will eventually, in any non-trivial project,) you'll be left with no idea what's happening or why. |
I am debugging some code and I want to find out when a particular dictionary is accessed. Well, it's actually a class that subclass dict and implements a couple extra features. Anyway, what I would like to do is subclass dict myself and add override __getitem__ and __setitem__ to produce some debugging output. Right now, I have
class DictWatch(dict):
def __init__(self, *args):
dict.__init__(self, args)
def __getitem__(self, key):
val = dict.__getitem__(self, key)
log.info("GET %s['%s'] = %s" % str(dict.get(self, 'name_label')), str(key), str(val)))
return val
def __setitem__(self, key, val):
log.info("SET %s['%s'] = %s" % str(dict.get(self, 'name_label')), str(key), str(val)))
dict.__setitem__(self, key, val)
'name_label' is a key which will eventually be set that I want to use to identify the output. I have then changed the class I am instrumenting to subclass DictWatch instead of dict and changed the call to the superconstructor. Still, nothing seems to be happening. I thought I was being clever, but I wonder if I should be going a different direction.
Thanks for the help! |

i am learning python, and i am having troubles with saving the output of a small function to file. My python function is the following:
#!/usr/local/bin/python
import subprocess
import codecs
airport = '/System/Library/PrivateFrameworks/Apple80211.framework/Versions/Current/Resources/airport'
def getAirportInfo():
arguments = [airport, "--scan" , "--xml"]
execute = subprocess.Popen(arguments, stdout=subprocess.PIPE)
out, err = execute.communicate()
print out
return out
airportInfo = getAirportInfo()
outFile = codecs.open('wifi-data.txt', 'w')
outFile.write(airportInfo)
outFile.close()
I guess that this would only work on a Mac, as it references some PrivateFrameworks.
Anyways, the code almost works as it should. The print statement prints a huge xml file, that i'd like to store in a file, for future processing. And here start the problems.In the version above, the script executes without any errors, however, when i try to open the file, i get an error message, along the lines of error with utf-8 encoding. Ignoring this, opens the file, and most of the things look fine, except for a couple of things:
some SSID have
non-ascii characters, like ä, ö and ü. When printing those on the screen, they are correctly displayed as\xc3\xa4and so on. When I open the file it is displayed incorrectly, the usual random garbage.
some of the xml values look like these when printed on screen: Data("\x00\x11WLAN-0024FE056185\x01\x08\x82\x84\x8b\x96\x0c\ ⦠x10D\x00\x01\x02") but like this when read from file: //8AAAAAAAAAAAAAAAAAAA==
I thought it could be an encoding error (seen as the Umlauts have problems, the error message says something about the utf-8 encoding being messed up, and the text containing \x type of characters), and i tried looking here for possible solutions. However, no matter what i do, there are still errors:
adding an additional argument 'utf-8' to the codecs.open yields a
UnicodeDecodeError: 'ascii' codec can't decode byte 0x9a in position 24227: ordinal not in range(128)and the generated file is empty.
explicitly encoding to utf-8 with
outFile.write(airportInfo.encode('utf-8'))before saving results in the same error
not being an expert, i tried decoding it, maybe i was just doing the exact opposite of what needed to be done, but i got an
UnicodeDecodeError: 'utf8' codec can't decode byte 0x8a in position 8980: invalid start byte
The only the thing that worked (unsurprisingly), was to write the repr() of the string to file, but that is just not what i need, and also i can't make a nice .plist of a file full with escape symbols.
So please, please, can somebody help me? What am i missing? If it helps, the type that gets saved in airportInfo is str (as in type(airportInfo) == str) and not u |
Use reduction to show that the following function is not computable, where P is any python program that takes a single input x:
sotrue(P) = true, if P(x) returns true for every value of x,
sotrue(P) = false, otherwise (if P(x) returns False or does not halt for at least one value of x)
The proof is proof by contradiction, and the goal is to find a way to compute halt, given a supposed algorithm for sotrue(P). Assuming that soTrue can be computed, I want to reach the contradiction that halt is computable. Here is the algorithm I created:
def halt (f, i):
def sotrue(P):
...code for sotrue goes here...
def ff(x)
f(i)
return true
return soTrue(ff)
So halt(f, i) computes halt! This is a contradiction since halt is known to not be computable! By contradiction, sotrue(P) is also not computable.
MY QUESTION IS: The algorithm I made seems too simple to be true. Could anyone point out if there is some problem with my algorithm or suggest a way to include the case when P(x) returns False since my proof does not include it, but rather is based on the "does not halt" part of the problem? |

Comment fonctionnent les pipes et les commandes shell avec Python
Bonjour,
J'ai de la difficulté à comprendre comment les redirections fonctionnent avec les commandes shell et Python. Par exemple, si dans un shell bash je tape:
aa | bb
Si je tape la commande précédente, cela veut dire que la sortie de la commande 'aa', stdout, sera l'entrée pour la commande 'bb', stdin, n'est-ce pas?
Mon problème se trouve à cette ligne de code en Python :
subprocess.call(["xsel", "-b", "-i"], stdin=tmp_file)
L'entrée pour la commande 'xsel' se trouve avec le fichier tmp_file. Cette commande fonctionne très bien. Ce que je ne comprends pas est que j'ai dû employer l'option '-i' qui est définie dans la doc de xsel de la façon suivante :
-i, --input Read standard input into the selection
Ma question est pourquoi dois-je employer cette option?
Par exemple, si je tape dans le shell bash :
echo xx | xsel
xsel lit son information depuis l'entrée standard qui est alimentée par la commande 'echo', n'est-ce pas? Pourquoi n'ai-je pas à employer l'option -i comme pour ma ligne de code Python?

Re : Comment fonctionnent les pipes et les commandes shell avec Python
parce que le shell, c'est pas du python.
Chacun a sa syntaxe et son fonctionnement distinct.
By default, this program outputs the selection without modification if both standard input and standard output are terminals (ttys).
Otherwise, the current selection is output if standard output is not a terminal (tty), and the selection is set from standard input if standard input is not a terminal (tty).
Alors effectivement depuis Python, il n'y pas de notion de pipe au sens shell, c'est le call python qui "déverse" le contenu du fichier dans l'entrée de la commande.
Comme si sous shell, on avait fait:
cat tmp_file | xsel

Re : Comment fonctionnent les pipes et les commandes shell avec Python
Bonjour,
Comme l'indique l'extrait de man xsel (Maisondouf #2), l'entrée standard est traitée différemment si c'est un terminal.
Ces trois commandes vont bien lire l'entrée standard :
cat tmp_file | xselxsel <tmp_filexset -i # Lecture sur le terminal
mais pas celle-ci :
xsel

Re : Comment fonctionnent les pipes et les commandes shell avec Python
OK. C'est ce que je vois. Donc on peut détecter si une entrée ou une sortie est un terminal. Je ne savais pas cela.
Cela ne me semble pas être en accord avec la doc qui dit:
Otherwise, the current selection is output if standard output is not a terminal (tty), and the selection is set from standard input if standard input is not a terminal (tty).
Ça dit que ça lit l'entrée standard donc je ne vois pas pourquoi je dois employer l'option -i.

En effet c'est bizarre ton histoire, et surtout je n'ai pas le bug chez moi... c'est quoi ta version de python/xsel ?
En même temps, l'auteur lui-même précise que son algo de defaulting est assez limite (src) et qu'il vaut mieux utiliser les options explicites comme le -i ici.
Mais bon je suis curieux de voir comprendre le pourquoi du comment. Au hasard, est-tu sûr que ton tmp_file ne vaut pas justement sys.stdin ?

Non, je ne crois pas. Voici le code Python de mon petit script:

# store the result in the clipboard
import subprocess
import tempfile
sel = subprocess.check_output("xsel")

Re : Comment fonctionnent les pipes et les commandes shell avec Python
ton code me donne une idée:
- essaye laisser le mode par défaut (lecture+ecriture et binaire) sur ton tempfile
- essaye d'appeler .flush() sur ton file descripteur histoire d'être sûr d'avoir tout est écrit avant de lancer ton process
avec ça ça devrait mieux marcher, tu confirmes ?
OK, ça expliquerait les choses.
En fait non... le code source est très clair: xsel va lire l'entrée standard ssi isatty(0) renvoie True, et après un rapide test chez moi ce n'est pas le cas dans le cas d'un appel depuis subprocess.call() avec l'option stdin settée à un fichier.
D'où l'idée qu'il n'y arrive pas parce que le fichier n'est pas prêt.

As requested I'm posting this an answer. I wrote a short sage script to check the primality of numbers of the form $10^n+333$ where $n$ is in the range $[4,2000]$. I found that the following values of $n$ give rise to prime numbers:
$$4,5,6,12,53,222,231,416.$$
Edit 3: I stopped my laptop's search between 2000 and 3000, since it hadn't found anything in 20 minutes. I wrote a quick program to check numbers of the form $10^n+3*10^i+33$. Here are a couple

There seemed to be plenty of numbers of this form and presumably I could find more if I checked some of the other possible forms as outlined by dr jimbob.
Note: I revised the post a bit after jimbob pointed out I was actually looking for primes that didn't quite fit the requirements.
Edit 4: As requested here are the sage scripts I used. To check if $10^n+333$ was prime:
for n in range(0,500):
k=10^n+333
if(is_prime(k)):
print n
And to check for numbers of the form $10^n+3*10^i+33$:
for n in range(0,500):
k=10^n+33
for i in range(2,n):
l=k+3*10^i
if(is_prime(l)):
print l

PodSixNet mailing list (great for getting help)
PodSixNet is a lightweight network layer designed to make it easy to write multiplayer games in Python. It uses Python's built in asyncore library and rencode.py (included) to asynchronously serialise network events and arbitrary data structures, and deliver them to your high level classes through simple callback methods.
Each class within your game client which wants to receive network events, subclasses the ConnectionListener class and then implements Network_* methods to catch specific user-defined events from the server. You don't have to wait for buffers to fill, or check sockets for waiting data or anything like that, just do connection.Pump() once per game loop and the library will handle everything else for you, passing off events to all classes that are listening. Sending data back to the server is just as easy, using connection.Send(mydata). Likewise on the server side, events are propagated to Network_* method callbacks and data is sent back to clients with the client.Send(mydata) method.
If you find a bug, please report it on the mailing list or the Google code issues page.
For users of the Construct game making environment for Windows, there is a tutorial on doing multiplayer networking with PodSixNet, here. Thanks to Dave Chabo for contributing this tutorial.
First make sure you have Python 2.4 or greater installed.
Next you'll want to get the PodSixNet source.
You can either check the latest cutting-edge code out of the bzr repository:
Of if you prefer SVN check it out of the Google code project:
Or you can download a tarball of the latest release (version 78).
The module is found inside a subdirectory called PodSixNet within the top level folder. There's an __init__.py inside there, so you can just copy or symlink the PodSixNet sub-directory into your own project and then do import PodSixNet, or else you can run sudo setup.py install to install PodSixNet into your Python path. Use sudo setup.py develop if you want to stay up to date with the cutting edge and still be able to svn/bzr up every now and then.
By default PodSixNet uses a binary encoder to transfer data over the network, but it can optionally use the JSON format or other formats supported by a serialiser which has 'dumps' and 'loads' methods. If you want to serialise your data using JSON you can change the first line of Channel.py to 'from simplejson import dumps, loads' or use the built-in json library in Python 2.6 or higher. This will allow you to write game clients in languages that can't read the 'rencode' binary format, such as Javascript.
Chat example:
python examples/ChatServer.pypython examples/ChatClient.py
Whiteboard example:
python examples/WhiteboardServer.pypython examples/WhiteboardServer.py
LagTime example (measures round-trip time from the server to the client):
python examples/LagTimeServer.pypython examples/LatTimeClient.py
You will need to subclass two classes in order to make your own server. Each time a client connects, a new Channel based class will be created, so you should subclass Channel to make your own server-representation-of-a-client class like this:
from PodSixNet.Channel import Channel
class ClientChannel(Channel):
def Network(data):
print data
def Network_myaction(data):
print "myaction:", data
Whenever the client does connection.Send(mydata), the Network() method will be called. The method Network_myaction() will only be called if your data has a key called 'action' with a value of "myaction". In other words if it looks something like this:
data = {"action": "myaction", "blah": 123, ... }
Next you need to subclass the Server class like this:
from PodSixNet.Server import Server
class MyServer(Server):
channelClass = ClientChannel
def Connected(self, channel, addr):
print 'new connection:', channel
Set channelClass to the channel class that you created above. The method Connected() will be called whenever a new client connects to your server. See the example servers for an idea of what you might do each time a client connects. You need to call Server.Pump() every now and then, probably once per game loop. For example:
myserver = MyServer()
while True:
myserver.Pump()
sleep(0.0001)
When you want to send data to a specific client/channel, use the Send method of the Channel class:
channel.Send({"action": "hello", "message": "hello client!"})
To have a client connect to your new server, you should use the Connection module. See pydoc Connection for more details, but here's a summary:
Connection.connection is a singleton Channel which connects to the server. You'll only have one of these in your game code, and you'll use it to connect to the server and send messages to the server.
from Connection import connection
# connect to the server - optionally pass hostname and port like: ("mccormick.cx", 31425)
connection.Connect()
connection.Send({"action": "myaction", "blah": 123, "things": [3, 4, 3, 4, 7]})
You'll also need to put the following code once somewhere in your game loop:
connection.Pump()
Any time you have an object in your game which you want to receive messages from the server, subclass ConnectionListener. For example:
from Connection import ConnectionListener
class MyNetworkListener(ConnectionListener):
def Network(self, data):
print 'network data:', data
def Network_connected(self, data):
print "connected to the server"
def Network_error(self, data):
print "error:", data['error'][1]
def Network_disconnected(self, data):
print "disconnected from the server"
def Network_myaction(data):
print "myaction:", data
Just like in the server case, the network events are received by Network_* callback methods, where you should replace '*' with the value in the 'action' key you want to catch. You can implement as many or as few of the above as you like. For example, NetworkGUI would probably only want to listen for the _connected, _disconnected, and _error network events. The data for _error always comes in the form of network exceptions, like (111, 'Connection refused') - these are passed straight from the socket layer and are standard socket errors.
Another class might implement custom methods like Network_myaction(), which will receive any data that gets sent from the server with an 'action' key that has the name 'myaction'. For example, the server might send a message with the number of players currently connected like so:
channel.Send({"action": "numplayers", "players": 10})
And the listener would look like this:
from Connection import ConnectionListener
class MyPlayerListener(ConnectionListener):
def Network_numplayers(data):
# update gui element displaying the number of currently connected players
print data['players']
You can subclass ConnectionListener as many times as you like in your application, and every class you make which subclasses it will receive the network events via named Network callbacks. You should call the Pump() method on each object you instantiate once per game loop:
gui = MyPlayerListener()
while 1:
connection.Pump()
gui.Pump()

Twisted is a fantastic library for writing robust network code. I have used it in several projects in the past, and it was quite nice to work with. That said, Twisted:

As for the second part of the question: row wise operations, even optimised ones, using pandas apply, are not the fastest solution there is. They are certainly a lot faster than a python for loop, but not the fastest. You can test that by timing operations and you'll see the difference.
Some operation could be converted to column oriented ones (one in my example could be easily converted to just df['a'] + df['b']), but others cannot. Especially if you have a lot of branching, special cases or other logic that should be perform on your row. In that case, if the apply is too slow for you, I would suggest "Cython-izing" your code. Cython plays really nicely with the NumPy C api and will give you the maximal speed you can achieve.
Or you can try numba. :) |

Déconnexion sur Batterie [Samsung]
Bonjour à tous
J'ai un problème récurrent avec mon wifi quelque soit l'os ou la version de celui-ci. Après un petit temps sur batterie ( entre 5min et 1h) il se déconnecte de plus le gestionnaire de connexion ne montre plus aucun wifi.
Sur Windows, l'outils de résolution de problème redémarre la carte et tout rentre dans l'ordre, si on omet la déconnexion ...
Je n'ai pas trouver la commande qui permet de redémarrer la carte, ou une solution durable. Par contre si j'introduits :
sudo /etc/init.d/networking restart
ça fait tout planter sous 12.10, et sous 11.10 rien ne se passait ...
Merci d'avance

Re : Déconnexion sur Batterie [Samsung]
Bonsoir,
es-ce que ton portable est passé en veille quand il était sur batterie ? cela me fait penser a un pb de gestion d’énergie, regarde dans le bios si tu n'as pas des paramètres a ce niveau la ...
la prochaine fois que cela t'arrive, et avant de bidouiller quoique ce soit donne le retour de

Re : Déconnexion sur Batterie [Samsung]
Tout d'abord merci d'avoir pris le temps de me répondre.
Au niveau de la veille, non ce n'est pas le cas. Ca arrive que je vienne de boot, sortir de veille, hibernation ou danse la polka! Mais je vais checker le bios; je n'y avais pas pensé.
Je poste le retour dès qu'il me lache

Re : Déconnexion sur Batterie [Samsung]
mais justement une gateway sur 192.168.1.20 c'est pas courant.... la gateway (paserelle en français) désigne la machine (routeur/pc qui partage internet) par laquelle vont transiter les informations pour allez (et venir) d'internet....c'est toi qui a mis cette info, c'est bien cela ?

Re : Déconnexion sur Batterie [Samsung]
Chez moi je suis l'unique poste ubuntu au sein d'un réseau windows avec entre autre un vpn et toute une floppée de serveur dont je ne suis pas admin, ce qui pourrais expliquer l'ip "étrange" vu qu'il ne vient pas d'une box
je ne comprend pas trop "mis" l'info, j'ai simplement c/c ce qu'avais pondu le "wificheck" et j'en ai refais un pour le wifi que j'utilise actuellement.
Mais mon soucis vient très clairement de ma machine car ca m'arrive partout.

Re : Déconnexion sur Batterie [Samsung]
Bon il semblerais que j'ai atteint un nouveau niveau, la déconnexion se fait également sur secteur ( chose que je n'avais jamais constater en 2 ans d'utilisation...).
Juste la commande de redémarrage de la carte me serais bien utile.

Re : Déconnexion sur Batterie [Samsung]
Salut,
Sur batterie tu peux essayer de désactiver le mode économie d'énergie de la carte wifi. Voir ici : http://forum.ubuntu-fr.org/viewtopic.php?id=1042031

I recently stumbled upon this and am checking here to see if what I am proposing is indeed feasible and can be considered a breach of privacy.
For obvious reasons I am not revealing the website which exhibits this property
The URLs are of the format :
https://xxxxxxxxyyyyyzzzz/xyz/<6 digit rand>_<17 digit rand>_<10 digit rand>_n.jpg
And requesting the above link will return you an image. Now, as you can see, the entropy of the possible URLs are quite large. But note that they are all integers(0-9).
This website hosts contents of millions of people ;) and my guess is that at least 10% of the URLs contained within these random number will work. Of course, its just a guess.
My question is : is this feasible ? Is my Claim true ? My presumption here is that these random numbers may be a non-cryptographic hash of some string. There is no way to confirm the above sentence. For the sake of this question, lets assume it does.
My code to generate these links looks like so (just a snippet)
first = str(random.randint(100000,999999))
second=str(random.randint(10000,99999))+str(random.randint(10000,99999))+str(random.randint(10000,99999))+str(random.randint(10,99))
third= str(random.randint(10000,99999))+str(random.randint(10000,99999))
test='https://<URL>/'+first+'_'+second+'_'+third+'_n.jpg'
try:
image=urllib2.urlopen(test)
print (image.read()).__len__()
except:
print "fail"
I have not tried to run this for more than tens of requests for the fear of my IP being blocked by the server for excessive requests. I do not intend to either. Just want to clarify if my understanding is right.
P.S: Am not a python developer, so please forgive if my code is ugly (suggestions will be happily taken to improve) |
I'am using Python 2.5 on App Engine and tried to get the Jinja2 ModuleLoader to work.
To initialize the environment I use :
@staticmethod # get Jinja environment (global)
def get_new(): # and initialize Jinja environment
if myEnv._my_env == None :
path = os.path.join(os.path.dirname(__file__), 'compiled')
myEnv._my_env = Environment(loader = ModuleLoader(path))
return myEnv._my_env
'compiled' is a directory in my GAE project. But I receive TemplateNotFound exceptions all the time??
I compiled the templates using :
env = Environment(extensions=['jinja2.ext.i18n'])
env.filters['euros'] = Euros
db_runtimes = Runtimes.all() # the html templates saved in a db.Blob
for each in db_runtimes.fetch(999) :
key = each.key().name()
source = db.Blob(each.content).decode('utf-8')
name = key.split('.')[0]
raw = env.compile(source, name=name, filename=name + '.py', raw=True)
each.compiled = db.Blob(raw.encode('utf-8')) # compile and save the .py
each.put()
The resulting code looks fine. Any ideas? I hope you can help me. This article from Rodrigo Moraes shows that loading templates from python modules is very fast. But in this 2009 proof of concept he "hacked" the Jinja code to be able to run the code. I think the ModuleLoader should do the same job. https://groups.google.com/group/pocoo-libs/browse_thread/thread/748b0d2024f88f64
The testmod.py looks like this :
from __future__ import division
from jinja2.runtime import LoopContext, TemplateReference, Macro, Markup, TemplateRuntimeError, missing, concat, escape, markup_join, unicode_join, to_string, identity, TemplateNotFound
name = u'testmod.py'
def root(context, environment=environment):
if 0: yield None
yield u'<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"\n"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">\n<html xmlns="http://www.w3.org/1999/xhtml">\n<head>\n<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />\n<title>TEST</title>\n</head>\n<body>\n\t<p>test template</p>\n</body>\n</html>'
blocks = {}
debug_info = ''
And the page handler :
def get(self):
my_env = myEnv.get()
page = 'testmod.py'
template = my_env.get_template(page)
self.response.out.write(template.render({}))
I'have also tried to get the template without the .py extension. |
i am trying to convert a date string to date format

however when the year is in two digit it breaks

any ideas?? |
I'm asked to create a method that returns the number of occurrences of a given item in a list. I know how to write code to find a specific item, but how can I code it to where it counts the number of occurrences of a random item.
For example if I have a list [4, 6 4, 3, 6, 4, 9] and I type something like
s1.count(4), it should return 3 or s1.count(6) should return 2.
I'm not allowed to use and built-in functions though.
In a recent assignment, I was asked to count the number of occurrences that sub string "ou" appeared in a given string, and I coded it
if len(astr) < 2:
return 0
else:
return (astr[:2] == "ou")+ count_pattern(astr[1:])
Would something like this work??
def count(self, item):
num=0
for i in self.s_list:
if i in self.s_list:
num[i] +=1
def __str__(self):
return str(self.s_list)

Re : /* Topic des codeurs [7] */
J'ai un exam sur les listes chainée aussi, et aussi des exos à rendre dessus, mais pour le premier j'ai préféré utiliser un tableau et pour le second j'avais trop de mal avec le cours, j'ai pas rendu de rendu, je m'y mettrais plus sérieusement dessus à partir de demain...
@ grim : Bah pour le moment j'ai un peu de mal avec le fonctionnement du passage d'un élément à un autre, sinon je comprends le principe avec le pointeur qui pointe sur l'élément suivant ou précédent.
Enfin je travaillerais ça demain et la semaine prochaine.
Pour le moment j'essaie de le faire avec un simple tableau, ça a plutôt l'air d'aller, j'arrive a gérer un ensemble de parenthèse, j'ai déjà réussi à créer une calculatrice ultra basique, et une fonction qui permet également de convertir un "nombre" (entré sous forme de caractère) en "vrai" nombre. Donc créer une calculatrice qui gère les priorité est déjà un peu plus complexe je trouve, je bloque un peu dessus, surtout à l'endroit ou il faudrait stocké le résultat d'une opération, parce qu'avec seulement des retour de fonction ça me semble un peu chaud...

Re : /* Topic des codeurs [7] */
Mettons, tu dois analyser l'expression suivante :
5 * ( ( ( 9 + 8 ) * ( 4 * 6 ) ) + 7 )
Voici la même expression, en forme postfixée :
5 9 8 + 4 6 * * 7 + *
Pour arriver à cette forme, voici l'algo, tu lis ton expression originale de gauche à droite et :
- Si le symbole est une opérande, tu l'écris.
- Si c'est un opérateur, tu l'empile (tu ne l'écris pas).
- Si c'est une parenthèse ouvrante "(", tu ne fais rien.
- Si c'est une parenthèse fermante ")", alors tu dépile l’opérateur (le dernier que tu as empilé, forcément)
et tu l'écris.
A toi de voir maintenant, comment tu peux, dans ton programme, te servir de cette forme simplifiée et du système de piles pour fournir un résultat
Je vais y réfléchir si je trouve le temps, tiens ! Ça m'amuse ^^ (Peut être dès ce soir, même...)
Un conseil, ne te lance pas à corps perdu dans un programme (vécu, j'en ai déjà payé le prix) sans y avoir pensé avant sur le papier. La programmation, c'est réfléchir et se servir de sa logique et de ses connaissances, et pas seulement taper sur un clavier si je puis dire ainsi

Re : /* Topic des codeurs [7] */
Si je suis l’algo de :!pakman (j’ai dû ajouter un petit truc pour que ça tourne quand même), ça donne :
#!/usr/bin/env python3
from sys import argv
from operator import add, sub, mul, truediv
OP = { '+': add, '-':sub, '*':mul, '/':truediv }
if __name__ == '__main__':
# Conversion.
stack = []
rpn = []
for x in argv[1]:
if str.isdigit(x):
rpn.append(x)
elif x in '+-*/':
stack.append(x)
elif x == ')':
rpn.append(stack.pop())
rpn.extend(stack)
# Evaluation.
stack = []
for x in rpn:
if x in '+-*/':
a = float(stack.pop())
b = float(stack.pop())
stack.append(OP[x](a, b))
else:
stack.append(x)
print(stack.pop())
À noter que cette implémentation est loin d’être correcte : ne gère pas quand les nombres font plus d’un chiffre (je ne découpe pas la chaîne en token), ne gère pas la priorité (l’algo de conversion en RPN de :!pakman est un peu trop naïf )
Mais ça donne une idée de base.

Ma méthode est un peu longue à expliquer en texte, alors je vais montrer le schéma que j'ai fait pour que ce soit plus compréhensible (au fait pour le moment je n'ai encore rien codé, je fais des notes ou je schématise mon algo )
Enfin bon c'est pas super clair, mais j'espère que c'est compréhensible.
Je fais quand même quelques précisions : donc il faut penser que le tableau est parcouru par une boucle du type "tant que tab[i] différent de '\0'" puis que m, tout comme i est incrémenté de 1 par tour de boucle.
(m et i ayant tous deux été initialisé avant la boucle.)
Si tab[i] contient une parenthèse fermante, une boucle se crée. (enfin la suite doit être suffisamment claire sur l'image je pense)
@ grim : Merci Pour le code, je vais essayer de le travailler pour voir si j'obtiens un résultat, normalement je devrais bosser la fonction jusqu'à au moins mardi, donc d'ici là je pense je devrais avoir trouvé un moyen de faire la calculatrice avec les deux méthodes (enfin j'espère bien ).

Un des concepts d'Epitech est de stimuler au maximum l'esprit imaginatif du codeur pour trouver la solution, avec un minimum de moyen. À part le my_putchar, toutes les fonctions utilisées (ou presque, malloc comme type d'exeption par exemple) sont codées par nous-même.

C'est sûr que présenté comme ça ça a l'air tentant mais ils vont quand même bien plus vite que la musique. Avant de pouvoir inventer tes propres solutions originales, il faut que tu étudies les solutions que d'autres ont proposé pour pouvoir voir leurs points forts/faibles/améliorables/issus de compromis/etc. Ensuite seulement tu seras capable de trouver de vraies solutions.
En particulier, si tu veux savoir coder, il faut que tu bouffes des maths. Church et Turing étaient des mathématiciens qui ont inventé la théorie de la calculabilité (de deux façons différentes) pour résoudre des questions purement mathématiques très, mais alors, très compliquées.
En ce qui me concerne, si tu bosses ça dans ton coin et que tu viens poser des questions ici, j'y répondrai du mieux que je peux ^^ J'ose espérer qu'on vous a parlé de machines de Turing et de classes de complexité ?

C'est vrai. Tu codes (nathéo) des structures de données, et je pense que si on vous fait coder des structures de données sans vous parler avant de complexité algorithmique, vos structures seront peut-être mal choisies.
Quand utiliser un arbre binaire ? Quand utiliser une liste chaînée ? Quand utiliser une pile ? etc.
Si tu te retrouve à résoudre un problème en utilisant une pile alors que la solution la plus optimisée est l'arbre binaire par exemple, ton algo fonctionnera, mais sera d'une lenteur affolante, et ceci proportionnellement au volume de données traitées. A petite échelle tu ne t'en rendra pas compte, mais lorsque tu le fera fonctionner avec de grands volumes de données, tu va le sentir

Es-ce que tu essaierait pas de sérialiser un objet? Je vois "XMLSerializer" dans le stack. Peut-être une référence à un objet, du genre, A contiens B, et B contiens une référence vers A (donc le serializer passe en boucle sans jamais pouvoir s'en sortir car il fait A->B->A->B->A->B....) ?

Bah, le truc, c'est que j'n'essaye pas de sérialiser moi-même quoi que ce soit : je laisse l'API SOAP se débrouiller toute seule, sans trop savoir ce qu'elle fait.
Mais trouvé : en fait, c'est juste que ça n'aime pas les java.awt.Point : je les ai viré et remplacé par des entiers en vrac, et tout est rentré dans l'ordre (bon, j'ai eu aussi quelques soucis avec les listes vides qui se transforment en null, mais ç't'autre chose). Du coup, ça marche
(Par contre, j'voulais faire un truc bien propre, et finalement, c'est codé complètement à l'arrache, mais bon…)
Donc l'archive Jar est dispo pour qui veut faire joujou avec. Je n'met pas le lien (pas envie que ce soit référencé avant que je change de machine), mais il s'appelle « StreamsEngine.jar » et est à la racine de mon serveur. Vous pouvez jouer à la version Web sur le port 9999, aussi, mais ça n'a pas grand intérêt actuellement, vu qu'il n'y a qu'un petit niveau de test…

Bon, je redemande, au cas où. Je cherche des cours de Java parce que je suis un peu à la ramasse. Je voudrais un cours assez complet et en français (j’ai déjà suffisamment de mal pour ne pas me casser la tête sur de l’anglais).
Vous m’aviez déjà conseillé développez.com, mais il y a pas mal de tutos, et je ne sais pas trop comment choisir…

Le temps de chargement, j'pense que ça vient du fait qu'il récupère les infos et les images de base sur mon serveur la première fois, et que mon serveur n'est pas non plus super costaud. Par contre, les erreurs, ç'pas normal Surtout si tu as déjà chargé un niveau, normalement c'est enregistré en local après…

@arkseth: j'ai pas grand chose à apporter, à part… http://reinout.vanrees.org/weblog/2010/ … -rest.html
Yep, avant de commencer ce projet, j'étais bêtement sur la longueur d'onde de l'intervenant qui nous avait fait les TP d'AOS l'an dernier (en gros, il nous sortait que REST (qu'on a vu en deux temps trois mouvements, genre en intro, sans plus), c'était le vieux truc limité, et que maintenant on avait SOAP qui était largement mieux et moins limité) ; puis en creusant un peu (ce que j'n'avais pas spécialement pris le temps de faire à l'époque) pour faire ce truc-là, j'ai commencé à me rendre compte du niveau monumental d'absurdité de son truc (ce qui, curieusement, ne m'étonne pas trop de sa part⁽¹⁾).
De toute façon, le concept de WebService me déplaît plutôt pas mal (confer ça, par exemple). J'pense qu'un jour, quand j'aurai le courage, je re-ferai ce truc-là un peu plus proprement (genre avec une interface Python pour la version locale, un client Web dédié indépendant, et genre Git pour récupérer des niveaux), parce que c'est vrai qu'il en faut ; et puis pour faire un vrai truc en Java, je chercherai autre chose, avec peut-être des trucs différents dedans.
(1) Il faut dire qu'on ne s'appréciait pas beaucoup mutuellement. Enfin, c'est surtout lui qui ne m'aimait pas depuis qu'il m'avait sorti que je-ne-sais-plus-quoi n'était pas faisable et que je l'avais fait devant lui dans le quart d'heure suivant ^^

REST[ful] is all the rage right now.
Surtout dans Rails, qui est restful depuis le début (ou en tout cas depuis la version 2 au moins, les autres j'ai pas connu ).

Yep, c'est aussi un des trucs que j'ai découvert en creusant un peu et qui va à l'opposée de ce qu'avait sorti l'intervenant en question (à ma fac, on avait plein de super bons profs jusqu'en M1, et juste sur mon année de M2, ils ont dû mobiliser plein d'intervenants extérieurs et le niveau a bien baissé J'espère qu'ils ont pu arranger ça pour cette année).
D'ailleurs, j'veux bien un complément d'informations à ces sujets, si quelqu'un a de la bonne doc sous la main, ce sera toujours utile.

Bah, wikipedia est assez clair : REST est une architecture, SOAP est une bouse immonde un protocole.
C'est un peu comme quand les gens te disent qu'ils utilisent du XML. C'est pas un format, mais une spécification au-dessus du format : avec XML seul tu fais rien.

Interpolating between two function tables?
I’m building an inharmonic additive synthesizer, where the frequency relations of the partials are given by a breakpoint graph (a function object). I’d like to be able to interpolate between two function tables to get the partials’ frequencies. I can do some kind of interpolation with pattrstorage, but I haven’t been able to figure out how to use it to morph the data from two function tables. Also it seems to lose some of the points of the function table while doing the morph.
Any advice?

For some reason some of the loadbangs and loadmesses don’t seem to work, so you need to click some of the buttons in the main patch to get it initialized properly…
Any help is greatly appreciated, thanks in advance!
Have a look at the ej.linterp external from Emmanuel Jourdan :
It’s in the ejies 2.0 download.
It’s help file shows interpolation between two multisliders with the output displayed on a third multislider. It may help you out.
pattrstorage should morph between the two functions just fine IF the number of points is the same in each. If not, it will lose points, as it can’t do a one-to-one. So to make sure the number of points is the same, just have multiple points close to each other if need be to fill up the list length.
Also multislider might work for you too, and in some ways is easier to use. pattrstorage will work fine with that as well, again, assuming the list lengths are the same.
Thanks for the pointers!
Those ej externals seem really cool and the ej.linterp does seem to be able to pull off what I’m looking for. However, since this is a class project where the work should be a self-contained folder, I think I have to refrain from using anything that needs installation for now. Later I’ll use them for sure, though!
What I haven’t been able to pull off with patternstorage yet is how to have two different function objects and interpolate between them. I’d like to have the two function graphs on the screen simultaneously and a slider with which the user could interpolate between them (much like in the ej.linterp help file). Is this doable with pattrstorage?
Sounds like you’d need three functions: the first, the second, and the third is the interp between the two. the "recall $1 $2 $3" message would be used for this, where $1 and $2 are the stored slots you want to interp between, and $3 is a value from 0. to 1., where 0. is the same as slot 1, 1. is the same as slot 2, and 0.5 is halfway between.
So when you recall slots, they just need to go to the function you want. I’m not sure how to do this with just one pattrstorage though, and if you have two, I don’t think you can interp between slots on different pattrstorages. Anyone else weigh in on this? Would be good to know.
I suppose you could use a placeholder function (invisible) to hold the recalls, then based on the slot chosen, these values then go to one of your two display functions. just use a [gate] that toggles back and forth, or maybe choose the destination based on the slot number recalled (like odds go to one, evens to the other, use %2 to determine odd or even).
Probably don’t want to try setting the interp values back into a function that holds one of the slots, you could run into issues with the set messages and trying to create new slots. Better to use a third function that shows the interp result, or just use one for everything. If you use the "swap back and forth" technique above, you could have the other two functions on top of the real one, with transparent backgrounds, to show all three at once. Only the result one would be clickable.
Here’s an approach without pattr or externals.
It basically makes one list per breakpoint-envelope, interpolates between them and sets a third breakpoint object.
BTW, this way you can also do extrapolation (1.)
The interpolate-list subpatch maybe a bit cumbersome. I’m sure you could do this a lot more efficient with javascript.

That’s a nice approach. I don’t think the subpatch is cumbersome, I like what you did with the iteration and the zl slice/zl reg. Though you could probably have just used [iter] if you’re processing the elements one at a time. That said, anytime I see a new way to do recursion I’m definitely interested, especially with something like a list-interpolation.
Maybe the javascript version would be cleaner, but really you’d be doing the same thing: going through all the array elements, finding the difference between corresponding points, and applying the scale factor to determine the interp point. So it seems pretty much the same to me. Actually, using [vexpr] would be better here, process the lists all at once.
Anyone weigh in on the possible speed differences between these two approaches (max vs. js)? Assuming there are (say) thousands of points, where it would actually matter? Maybe jit.expr would be the best approach for speed with massive lists…
I would use vexpr. If you don’t set the scalarmode attribute of the vexpr $f1+$f2, it will automatically adapt to the smallest list. Finally if you want more than 128 points, you’ll have to set the first argument of zl iter 2 to something bigger.

Wow!
What a beautifully elegant solution.
Emmanuel, you’ve shown once more, that max patching belongs to the fine arts
i really appreciate that.
Thanks a lot, those are very inspiring pieces of code! They do exactly what I was looking for.
However, I’ve been thinking of another application of this list interpolation for my additive synth, which I’m not entirely sure how to pull off. I’d like to use interpolation between two breakpoint functions also for the amplitude envelopes of the partials in the following manner:
- Func1 gives the amplitude envelope for the lowest partial
- Func2 gives the amplitude envelope for the highest partial
- the partials in between would have amplitude envelopes interpolated between these two
(-> ie. if I had 21 partials, the 2nd partial would have an envelope of 95% f1 and 5% f2 and the 11th partial would have 50%/50% interpolation of the two functions.)
Or something of that sort, I thought it would be a fairly intuitive way of having a different amplitude envelope for the highest partials than the lowest ones. Should generate interesting results.
I suppose I could just duplicate for example the code by Emmanuel Jourdan 20 times, but I’m sure there’s a more elegant way?
Interestingly I was working on a similar project this summer. It is broken in 5.1 though. In 5.08 it works, haven’t found the time to fix it (maybe I should just send it to support?)
Its an additive synth with some interpolation including complex sustain loop modes… Have a look at it…
Another sort of primitive physical model of a bowed string I made for MaxFor Live is also using some function interpolation derived from my "Yet Another Additive Synth"…
Have fun…

Accéder au NAS DNS320 depuis toutes les applications sur Ubuntu 12.10
Bonjour, j'ai un soucis de connection à mon NAS DNS 320 sur Ubuntu 12.10.
J'arrive à y avoir accès en recherchant dans le réseau local mais je parviens pas à "accéder au NAS depuis toutes les applications"
J'ai déjà consulté plusieurs anciens topics du forum et des tutoriaux mais sans succès.
Voici ce que j'ai fais :sudo mkdir /media/nasgksudo gedit /etc/fstab
# Monter NAS
//192.168.1.4/Volume_1 /media/nas cifs guest,uid=1000,iocharset=utf8,codepage=unicode,unicode 0 0
Quand j'entre la commande:sudo mount -a
J'obtiens:
mount error(22): Invalid argument
Refer to the mount.cifs(8) manual page (e.g. man mount.cifs)
A noter que j'ai installé Fun Plug sur le NAS. Pensez-vous que ça ai pu interférer?
Sur Windows, je peux me connecter sans aucun mot de passe au NAS.
Mais pour me connecter en SSH via WinSCP ou Nautilus, je dois utiliser un login+password créé dans la foulée de l'installation de Fun Plug.
Est-ce que quelqu'un aurait une piste pour résoudre ce problème?
Un grand merci d'avance pour votre aide.

Re : Accéder au NAS DNS320 depuis toutes les applications sur Ubuntu 12.10
Salut,
j'ai également le même modèle de NAS. En l'absence de toute doc Linux du constructeur, je me la suis rédigée tout seul. Elle est sur http://coursinforev.org/dokuwiki/doku.php/dns320
Tu verras que pour monter le NAS, il faut d'abord identifier les partages avec la commande
showmount -e <IP_NAS>
et ensuite tu ajoutes dans ton fstab, une ligne du type:
# Entry for Backup on NAS
192.168.xxx.yyy:/mnt/HD/HD_a2/ /media/NAS nfs defaults,user,auto,noatime,intr,_netdev 0 0

Re : Accéder au NAS DNS320 depuis toutes les applications sur Ubuntu 12.10
Je pense que Volume 1 devrait suffire. Il faut par contre cocher dans le partage toutes les options CIFS, FTP et NFS. Par contre, as-tu aussi installé les paquets concernant nfs sur ton Ubuntu ?
Autre question qui m'intéresse personnellement: comment as-tu fait pour avoir le port 22 ouvert pour le SSH. Je n'arrive plus à l'activer.

Re : Accéder au NAS DNS320 depuis toutes les applications sur Ubuntu 12.10
J'ai créé sur l'administration du NAS un utilisation ayant tous les accès au partage "Volume_1".
J'ai également ajouter les options FTP et NFS qui n'étaient effectivement pas cochées.
Après un reboot du NAS, j'ai toujours la même erreur :showmount -e 192.168.1.4
clnt_create: RPC: Port mapper failure - Unable to receive: errno 111 (Connection refused)
En ce qui concerne ta question, je pense que le porte 22 a été ouvert quand j'ai installé Fun Plug sur le NAS (afin d'installer Transmission). J'ai suivi ce tutoriel :
http://klseet.com/index.php/d-link-dns- … n-plug/173
Comment puis-je faire pour installer les paquets nfs?
Merci
EDIT: J'ai installé les paquets nfs-kernel-server
EDIT2: Mais rien n'y fait, j'ai toujours le même message quand je tappe la commande showmount.
EDIT3: Je précise que quand je vais sur Nautilus > Connect to server, je peux me conencter en SSH porte 22 avec le login et password configuré lors de l'installation de Fun Plug.
Mon problème n'est-il pas lié à cette installation qui a créé un login SSH inexistant auparavant?

Re : Accéder au NAS DNS320 depuis toutes les applications sur Ubuntu 12.10
- Pour les paquets NFS, je trouve
~$ dpkg -l | grep nfs
ii liblockfile1 1.09-3 NFS-safe locking library
ii libnfsidmap2 0.25-1ubuntu2 NFS idmapping library
ii nfs-common 1:1.2.5-3ubuntu3.1 NFS support files common to client and server
J'ai cru comprendre que nfs-kernel-server n'était pas compatible de nfs-common.
- Si tu accèdes au NAS par Firefox, c'est déjà pas mal, mais cela ne correspond pas à tous les besoins.
- On peut aussi accéder par Raccourcis/Réseau ou par Raccourcis/Se connecter à un serveur, on choisit ensuite par exemple Partage Windows ou un autre protocole.

Re : Accéder au NAS DNS320 depuis toutes les applications sur Ubuntu 12.10
En faisant la même commande, je trouve :

ii nfs-common 1:1.2.6-3ubuntu2 amd64 NFS support files common to client and server

J'ai supprimé nfs-kernel-server.
Pour récapituler, j'arrive à accéder au NAS par les moyens suivants :
- firefox, en allant à l'adresse 192.168.1.4, j'accède au panel admin
- nautilus, en allant dans Files > Connect du server > connection par SSH avec login et password
- nautilus, en allant dans les raccourcis à gauche > Network > browse network > ...
Mais ce que je recherche, c'est d'accéder au NAS depuis les logiciels comme LibreOffie Writer (quand on clique sur Open/Save), ou tout autre logiciel. Pour cela, je dois ajouter un "lien" dans le dossier "media" d'Ubuntu mais je n'y parviens pas.
En ce qui te concerne, est-ce que tu as réussis cette manipulation? As-tu un lien direct vers ton NAS dans "media"?

Re : Accéder au NAS DNS320 depuis toutes les applications sur Ubuntu 12.10
Non, moi, je n'ai aucun problème (sur un des NAS). J'utilise en fait deux NAS dans deux associations...
D'un côté, serveur en 12.04 LTS, tout est OK. De l'autre, le serveur est encore en 10.04 LTS, je dois le changer bientôt. Mais sur le dernier, je n'arrive plus à le monter, alors qu'avant cela marchait parfaitement...
Si tu n'arrives en NFS, essaye autre chose. Dans la doc du NAS, il y a plusieurs options (§ Accès Ubuntu). N'oublie pas la fonction "Se connecter à un serveur" (que tu trouves à partir du fond d'écran en faisant Fichier/Se connecter à un serveur).

Is there a math expressions parser + evaluator for Python?
I am not the first to ask this question, but answers usually point to eval(). For instance, one could do this:
>>> safe_list = ['math','acos', 'asin', 'atan', 'atan2', 'ceil', 'cos', 'cosh', 'degrees', 'e', 'exp', 'fabs', 'floor', 'fmod', 'frexp', 'hypot', 'ldexp', 'log', 'log10', 'modf', 'pi', 'pow', 'radians', 'sin', 'sinh', 'sqrt', 'tan', 'tanh', 'abs']
>>> safe_dict = dict([ (k, locals().get(k, None)) for k in safe_list ])
>>> s = "2+3"
>>> eval(s, {"__builtins__":None}, safe_dict)
5
But this is not safe:
>>> s_badbaduser = """
... (lambda fc=(
... lambda n: [
... c for c in
... ().__class__.__bases__[0].__subclasses__()
... if c.__name__ == n
... ][0]
... ):
... fc("function")(
... fc("code")(
... 0,0,0,0,"KABOOM",(),(),(),"","",0,""
... ),{}
... )()
... )()
... """
>>> eval(s_badbaduser, {"__builtins__":None}, safe_dict)
Segmentation fault
Also, using eval for parsing and evaluating mathematical expressions just seems wrong to me.
I have found PyMathParser, but it also uses eval under the hood and is no better:
>>> import MathParser
>>> m=MathParser.PyMathParser()
>>> m.expression = s_badbaduser
>>> m.evaluate();
Segmentation fault
Is there a library available that would parse and evaluate mathematical expression without using Python parser? |

I would recommend to get some understanding of packaging-ecosystem (from the guide pointed by gotgenes) before attempting mindless copy-pasting.
Most of examples out there in the Internet start with

Introduction
As noted previously, I recently rehosted this blog on Google’s App Engine (GAE). Writing a small, but functional, blog engine is a useful exercise in learning a web framework. I wrote blog software to learn more about Django, and I ported it to App Engine to learn more about App Engine.
In this article, I recreate the steps necessary to build a blogging engine that runs under GAE.
Acknowledgments
I’m grateful to the following people for reviewing and commenting on this article before I published it.
In addition, the following people sent me some valuable insights and corrections after the article was published:
Bill Katz, for clarifying the querying of list properties.
Fernando Correia, for reminding me that unique keys do have associated unique IDs, forcing me to re-read that part of the GAE docs again.
Alexander Kojevnikov, for clarifying that the GAE user API works withGoogle accounts, not GMail accounts. (The difference is that a registeredGoogle user need not be a GMail user.) Alexander also pointed out thatQuery.fetch(1)can be more simply expressed asQuery.get().
Mark Lissaman, for pointing out a semantic error in the picoblogcode.

Caveats
Before I jump into the tutorial, there are a few caveats:
The point of this article is to build an App Engine application, to get to know some GAE internals. If you just want to host a blog on GAE, and you’re not interested in understanding the software involved, you might consider installing cpedialog, a blogging engine that will run on GAE.
I am certainthere are things about GAE that I could do better. I welcome corrections and suggestions; just drop me an email.
What this Blog Engine Supports
The blog engine outlined in this article is fully functional; this blog runs on similar software. However, it lacks a few features some people might want, such as:
Image uploading. I just haven’t put that in yet. When I do, I’ll updatethis article. In the meantime, I’m able to live without it by uploadingthe images via GAE’s appcfg.py updatecapability.
Comments. It’s easy enough to drop Disqus into your templates, if you want.
Integration into blog aggregators like Technorati. (There’s a follow-up article on this topic.)
It does have the following features, though:
Tag handling, including support for generating a tag cloud.
Support for RSS and Atom feeds.
Displaying articles by month or tag.
Template-driven theme customization.
Unpublished drafts.
Secured administration screens.
reStructuredText markup (instead of HTML) for the articles.
In short, it’s a serviceable blog engine, with simple, straightforward code you can customize as you see fit.
The Code
The source code for this blog engine is available on GitHub. See the Picoblog web page, at http://software.clapper.org/picoblog/
Get Going with App Engine
Register and Download
First, of course, you have to register with GAE and download the development kit. This article assumes you’ve already done that.
Create your Application
Next, from your GAE account, create a new application. You’ll have to create a unique identifier for the application. In this article, I use the application ID “picoblog”. You’ll want to use something else.
This article is not a tutorial on how to use the App Engine tools and web site; it’s an article about building a blog application. So, I’m not to go into details about how to create your application on the GAE site. Google’s wizard is easy enough to follow.
Open the App Engine Docs
You’ll want to have the online App Engine documentation available asyou develop your App Engine application. It wouldn’t hurt to review theGetting Starting section before jumping in.
Create your Local Application Directory
Create a directory called picoblog in which to do your work. Inthat directory, create a file called app.yaml:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23
application: picoblog
version: 1
runtime: python
api_version: 1
handlers:
- url: /static
static_dir: static
- url: /favicon.ico
static_files: static/favicon.ico
upload: static/favicon.ico
- url: /admin
script: admin.py
login: admin
- url: /admin/.*
script: admin.py
login: admin
- url: /.*
script: blog.py
This file configures your application. You can treat most of the top of the file as magic. For now, the parts we care about are:
:application: The application’s registered ID is “picoblog”.
:handlers: Each url entry is a regular expression GAE will match against incoming URL requests; on a match, it’ll run the associated script. In this case, we’re saying:
Any path starting with
/staticis resolved via the built-in static file handler. This is where we’ll put our images. So go ahead and create astaticdirectory underpicoblog.
Since browsers always look for
/favicon.ico, and I get tired of seeing all the “not found” messages in the logs, there’s an entry for an icon. It’s stored in thestaticdirectory.
The administrative screens (for creating and editing blog articles) live under ‘/admin’ and are secured: Only a Google account with administrative privileges on the project is allowed to get to them. They’re handled by the
admin.pyscript. We’ll be creating that script in thepicoblogdirectory.
Finally, the published blog itself matches everything else, and it’s handled by the
blog.pyscript. That script, too, will end up in thepicoblogdirectory.
Once you’ve created app.yaml, you can pretty much forget about itfor awhile.
Create the Data Model
The next step is to decide what data we’re storing in the database. Forthis blog engine, there’s a single object type in the database, called anArticle. It has the following properties (which would be columns in a SQLdatabase):
title: The 1-line title of the article
body: The body of the article, which is reStructuredText markup.
draft: Whether or not the article is a draft (i.e., not published) or not. Drafts are only visible in the administration screen.
published_when: The time the entry was published. In this context, “published” means “goes from being a draft to not being a draft”. This time stamp is initialized to the time the article is created, and it’s updated when the article is saved as a non-draft. (Toggling the “draft” flag multiple times will continue to update this time; you’re obviously free to change that behavior by hacking the code.)
tags: a list of tags (strings) assigned to the articles. May be empty.
id: a unique ID assigned to the article.
A note about the unique ID: GAE does not provide support for anautomatically incremented integer ID field the same way that Django does.An item in the datastore does have a unique key, accessible via thekey() method. Further, that key can be converted to a correspondingunique name or number (depending on how the key was assigned) by callingkey().id(). For instance:
1 2 3
article = Article(title='Test title')
article.put()
print article.key().id()
However, you cannot use this ID in a query. Quoting from the Keys and Entity Groups section of the GAE documentation:
Key names and IDs cannot be used like property values in queries.
However, you can use a named key, then store the name as a
property. You could do something similar with numeric IDs by
storing the object to assign the ID, getting the ID value using
obj.key().id(), setting the property with the ID, then storing the
object again.
So, that’s what we’re going to do.
The data model for our Article class looks like this:
1 2 3 4 5 6 7 8 9 10 11 12
import datetime
import sys
from google.appengine.ext import db
class Article(db.Model):
title = db.StringProperty(required=True)
body = db.TextProperty()
published_when = db.DateTimeProperty(auto_now_add=True)
tags = db.ListProperty(db.Category)
id = db.StringProperty()
draft = db.BooleanProperty(required=True, default=False)
If you’re familiar with Django, you’ll notice that it’s similar to Django’s data models, but not exactly the same.
Next, since I like to hide as much of the database API semantics inside themodel, I’m going to add a get_all() method that returns all articles, aget() method that returns a single article by ID, and a published()method that returns all non-draft articles. (The published() method willbe separated into two methods, so the query itself can be shared. More onthat later.)
1 2 3 4 5
@classmethod
def get_all(cls):
q = db.Query(Article)
q.order('-published_when')
return q.fetch(FETCH_THEM_ALL)
1 2 3 4 5
@classmethod
def get(cls, id):
q = db.Query(Article)
q.filter('id = ', id)
return q.get()
1 2 3 4 5
@classmethod
def published_query(cls):
q = db.Query(Article)
q.filter('draft = ', False)
return q
1 2 3
@classmethod
def published(cls):
return Article.published_query().order('-published_when').fetch(FETCH_THEM_ALL)
FETCH_THEM_ALL is an integer constant with a large value, definedat the top of the module.
NOTE: In the original version of the code, and in the zip files postedto the web site, FETCH_THEM_ALL is defined as follows:
1
FETCH_THEM_ALL = sys.maxint - 1
On a 64-bit local machine, sys.maxint will evaluate to a 64-bit number.But GAE is a 32-bit environment, so the code may fail on certain machines.The code in the GitHub repository has been corrected.
Finally, let’s add a save() method that does two important things:
Copies the GAE-assigned unique ID into our idfield, so we can use it in queries.
Updates the time stamp if the article being saved is going from draft to published status.
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26
def save(self):
previous_version = Article.get(self.id)
try:
draft = previous_version.draft
except AttributeError:
draft = False
if draft and (not self.draft):
# Going from draft to published. Update the timestamp.
self.published_when = datetime.datetime.now()
try:
obj_id = self.key().id()
resave = False
except db.NotSavedError:
# No key, hence no ID yet. This one hasn't been saved.
# We'll save it once without the ID field; this first
# save will cause GAE to assign it a key. Then, we can
# extract the ID, put it in our ID field, and resave
# the object.
resave = True
self.put()
if resave:
self.id = self.key().id()
self.put()
Okay, that’s the model. (See the source code for the complete file.)
Create the Administration Screens
Now let’s create the administration screens, so we can edit and create articles. We’ll create two screens.
The main administration screen contains three things:
A button to create a new article. Pressing this button creates an empty article and launches the Edit Article screen to edit it.
A button to go back to blog itself.
A list of the existing articles. The articles will be sorted in reverse chronological order, and each article’s date and title will be displayed. The article’s date and title will also be a hyperlink to the edit screen for the article. Further, drafts will be shown in red, to distinguish them from published articles.
The Edit Article screen contains
A text box for the the title
A text area for the body of the article, which is assumed to be reStructuredText
A text box for the list of tags (comma-separated)
A check box to indicate whether or not the item is a draft
To create these screens requires five files:
defs.pywill hold some constants that we share between all the blog scripts.
request.pywill hold a base class request handler, which is basically a place to hang logic that we need in every script.
admin.pycontains the Python code for the admin screens–the equivalent of a Djangoviews.pyfile for the admin screns.
admin-main.htmlis the template for the main administration screen.
admin-edit.htmlis the template for the Edit Article screen.
To keep things organized, we’ll store the templates in a templatessubdirectory.
The Templates
Let’s start with the templates.
GAE’s default template engine is Django’s template engine. If you don’t know Django’s template language, read the first few sections of the Django template language document. Describing Django templates is beyond the scope of this article.
Main Administration Screen Template
You can see the full template for the main administration screen here.
It consists of a link to the style sheet, some Javascript, some standard HTML layout, and this block of template logic:
1 2 3 4 5 6 7 8 9 10 11
<ul>
{% for article in articles %}
{% if article.draft %}
<li class="admin-draft">
{% else %}
<li class="admin-published">
{% endif %}
{{ article.published_when|date:"j F, Y" }}
<a href="/admin/article/edit/?id={{ article.id }}">{{ article.title \}}</a>
{% endfor %}
</ul>
This template code assumes that the variables passed to the template willinclude a Python list called articles, each element of which is anArticle object. We’ll see how that’s populated in the next section.
The style sheet link looks like this:
1
<link href="/static/style.css" rel="stylesheet" type="text/css"/>
Rather than use a template Include file '"style.css"' contains invalid characters or sequences directive topull the style sheet file inline at rendering time, we’re tellingthe browser to go get it. We’ll be using the same style sheet forall pages; using an external style sheet allows the browser tocache it.
The Style Sheet
To see the style sheet, follow this link. The style sheet is stored inthe static subdirectory, where it’ll be served by the GAE static filehandler.
The Edit Screen Template
The template for the edit screen is available here. The edit screen is slightly more complicated, since it has some Javascript to handle the various buttons. But overall, it’s still pretty simple as web screens go.
The View Code
The view code for the administration screens is in admin.py. It,too, is relatively simple. But first, let’s look at the two otherfiles we’re using to consolidate common logic.
defs.py
defs.py just contains some common constants:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15
BLOG_NAME = 'PicoBlog'
BLOG_OWNER = 'Joe Example'
TEMPLATE_SUBDIR = 'templates'
TAG_URL_PATH = 'tag'
DATE_URL_PATH = 'date'
ARTICLE_URL_PATH = 'id'
MEDIA_URL_PATH = 'static'
ATOM_URL_PATH = 'atom'
RSS2_URL_PATH = 'rss2'
ARCHIVE_URL_PATH = 'archive'
MAX_ARTICLES_PER_PAGE = 5
TOTAL_RECENT = 10
We’ll see how they’re used as we get further into this tutorial.
request.py
request.py contains our base request handler class:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43
import os
from google.appengine.ext import webapp
from google.appengine.ext.webapp import template
import defs
class BlogRequestHandler(webapp.RequestHandler):
"""
Base class for all request handlers in this application. This class
serves primarily to isolate common logic.
"""
def get_template(self, template_name):
"""
Return the full path of the template.
:Parameters:
template_name : str
Simple name of the template
:rtype: str
:return: the full path to the template. Does *not* ensure that the
template exists.
"""
return os.path.join(os.path.dirname(__file__),
defs.TEMPLATE_SUBDIR,
template_name)
def render_template(self, template_name, template_vars):
"""
Render a template and write the output to ``self.response.out``.
:Parameters:
template_name : str
Simple name of the template
template_vars : dict
Dictionary of variables to make available to the template.
Can be empty.
"""
template_path = self.get_template(template_name)
template.render(template_path, template_vars)
As you can see, it just contains some methods to make rendering templates a little simpler.
admin.py
Now we’re ready to look at the administration view code. First,we have some imports:
1 2 3 4 5 6 7 8
import cgi
from google.appengine.api import users
from google.appengine.ext import webapp
from google.appengine.ext.webapp import util
from models import *
import request
These are followed by the request handler classes:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81
class ShowArticlesHandler(request.BlogRequestHandler):
def get(self):
articles = Article.get_all()
template_vars = {'articles' : articles}
self.response.out.write(self.render_template('admin-main.html',
template_vars))
class NewArticleHandler(request.BlogRequestHandler):
def get(self):
article = Article(title='New article',
body='Content goes here',
draft=True)
template_vars = {'article' : article}
self.response.out.write(self.render_template('admin-edit.html',
template_vars))
class SaveArticleHandler(request.BlogRequestHandler):
def post(self):
title = cgi.escape(self.request.get('title'))
body = cgi.escape(self.request.get('content'))
id = int(cgi.escape(self.request.get('id')))
tags = cgi.escape(self.request.get('tags'))
published_when = cgi.escape(self.request.get('published_when'))
draft = cgi.escape(self.request.get('draft'))
if tags:
tags = [t.strip() for t in tags.split(',')]
else:
tags = []
tags = Article.convert_string_tags(tags)
if not draft:
draft = False
else:
draft = (draft.lower() == 'on')
article = Article.get(id)
if article:
# It's an edit of an existing item.
article.title = title
article.body = body
article.tags = tags
article.draft = draft
else:
# It's new.
article = Article(title=title,
body=body,
tags=tags,
id=id,
draft=draft)
article.save()
edit_again = cgi.escape(self.request.get('edit_again'))
edit_again = edit_again and (edit_again.lower() == 'true')
if edit_again:
self.redirect('/admin/article/edit/?id=%s' % id)
else:
self.redirect('/admin/')
class EditArticleHandler(request.BlogRequestHandler):
def get(self):
id = int(self.request.get('id'))
article = Article.get(id)
if not article:
raise ValueError, 'Article with ID %d does not exist.' % id
article.tag_string = ', '.join(article.tags)
template_vars = {'article' : article}
self.response.out.write(self.render_template('admin-edit.html',
template_vars))
class DeleteArticleHandler(request.BlogRequestHandler):
def get(self):
id = int(self.request.get('id'))
article = Article.get(id)
if article:
article.delete()
self.redirect('/admin/')
The file ends with some initialization logic and the main program:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15
application = webapp.WSGIApplication(
[('/admin/?', ShowArticlesHandler),
('/admin/article/new/?', NewArticleHandler),
('/admin/article/delete/?', DeleteArticleHandler),
('/admin/article/save/?', SaveArticleHandler),
('/admin/article/edit/?', EditArticleHandler),
],
debug=True)
def main():
util.run_wsgi_app(application)
if __name__ == "__main__":
main()
Let’s break this down a bit. First, the initialization logic at the bottom(that is, the creation of the webapp.WSGIApplication object) defines whatclasses (handlers) will handle which URLs within the /admin/ URL space.Recall that the app.yaml file points all /admin URLs to this file.The application variable further breaks those URLs down, so that certainURLs map to certain handlers. The list passed to the WSGIApplicationconstructor contains tuples; each tuple defines a URL mapping.
The first element of the tuple is a regular expression. Note that theregular expressions we’re using end with /?, allowing the trailing slash to be omitted in the URL.
The name of the class that will handle requests to URLs that match the regular expression.
Next, let’s look at some of the handlers. There are basically two kinds of handlers here:
Handlers that just display a page (i.e., retrieve data from the database and stuff it into a template).
Handlers that process form submissions.
Handlers that Only Display a Page
ShowArticlesHandler, NewArticlesHandler and EditArticlesHandler areexample of handlers that simply display a page. Here’s theShowArticlesHandler class again:
1 2 3 4 5
class ShowArticlesHandler(request.BlogRequestHandler):
def get(self):
articles = Article.get_all()
template_vars = {'articles' : articles}
self.render_template('admin-main.html', template_vars)
First, because it defines only the get() method, it supports just theHTTP GET semantics. (POST is not supported for the associated URL.)
The actual handler is simple: It retrieves all articles, whether draft orpublished, puts the resulting list in a dictionary, and uses thatdictionary to render the template. That’s it; that’s the entire handler.The NewArticleHandler is similarly simple.
The EditArticleHandler is a little more complicated, only because it hasto handle a few additional things:
1 2 3 4 5 6 7 8 9 10
class EditArticleHandler(request.BlogRequestHandler):
def get(self):
id = int(self.request.get('id'))
article = Article.get(id)
if not article:
raise ValueError, 'Article with ID %d does not exist.' % id
article.tag_string = ', '.join(article.tags)
template_vars = {'article' : article}
self.render_template('admin-edit.html', template_vars)
First, it determines whether the article being edited is in the database or not; if not, it throws an exception, because it should never be invoked on a non-existent article. (If it is, we have a bug.)
Next, it creates a comma-separated string from the list of tags, so the template can simply stuff that string into the tags edit box.
Handlers that Process Forms
The most complicated handler is the SaveArticleHandler class.Let’s look at that one again:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42
class SaveArticleHandler(request.BlogRequestHandler):
def post(self):
title = cgi.escape(self.request.get('title'))
body = cgi.escape(self.request.get('content'))
id = int(cgi.escape(self.request.get('id')))
tags = cgi.escape(self.request.get('tags'))
timestamp = cgi.escape(self.request.get('timestamp'))
draft = cgi.escape(self.request.get('draft'))
if tags:
tags = [t.strip() for t in tags.split(',')]
else:
tags = []
tags = Article.convert_string_tags(tags)
if not draft:
draft = False
else:
draft = (draft.lower() == 'on')
article = Article.get(id)
if article:
# It's an edit of an existing item.
article.title = title
article.body = body
article.tags = tags
article.draft = draft
else:
# It's new.
article = Article(title=title,
body=body,
tags=tags,
id=id,
draft=draft)
article.save()
edit_again = cgi.escape(self.request.get('edit_again'))
edit_again = edit_again and (edit_again.lower() == 'true')
if edit_again:
self.redirect('/admin/article/edit/?id=%s' % id)
else:
self.redirect('/admin/')
That one’s a little longer, but what it does is simple enough:
First, it retrieves all the form variables.
Next, if there are any tags in the form, it splits the tag string to make it into a list.
The tags are actually stored as GAE db.Categoryobjects, not strings, so the code calls a specialArticleclass method to convert the strings from the form intoCategoryobjects. (Consult the code for that conversion method; it’s trivial, and it’s not included here.)
It processes the Draft checkbox.
It attempts to load the referenced article. If the article exists, the handler updates its contents. Otherwise, it creates a new Article object with the specified ID.
Then, it saves the article.
If the edit_againrequest variable is set, then the handler redisplays the edit screen; otherwise, it displays the main administration screen again.
That’s it. We’ve finished our admin screens. Let’s take a look at them. Todo that, fire up a terminal window, change your working directory to thepicoblog directory, and run the following command. (You must have put theroot of the unpacked GAE toolkit in your path.)
dev_appserver.py .
You’ll see output something like this:
INFO 2008-08-06 02:51:26,336 appcfg.py] Server: appengine.google.com
INFO 2008-08-06 02:51:26,342 appcfg.py] Checking for updates to the SDK.
INFO 2008-08-06 02:51:26,444 appcfg.py] The SDK is up to date.
INFO 2008-08-06 02:51:26,534 dev_appserver_main.py] Running application
pico on port 8080: http://localhost:8080
You can now surf to http://localhost:8080/admin/ using your browser.
Here’s a screen shot of the main screen, showing several articles. The top-most article is a draft; the rest are published.
And here’s the edit screen for the draft article:
From a stylistic viewpoint, these screens are really simple. However, making them look fancier and slicker is simply a matter of fiddling with the templates and the stylesheet. The Python code doesn’t change.
The Markup Language
Rather than force the blogger (i.e., you or me) to enter HTML, I’ve chosen to use the reStructuredText (RST) markup language. Of course, this means the blog has to translate the RST text into HTML when someone wants to view the blog. We can either do that conversion when we save the article, or convert on the fly when someone visits the blog.
Converting the markup when we save the article is more efficient, but it means we have to store the generated HTML and reconvert all previously saved articles whenever we change the templates or the style sheet. It’s simpler to convert on the fly. If this strategy ends up causing a performance problem, we can always go back later and add page caching.
Docutils
To support RST, the first thing we have to do is make the Docutilspackage available to our running code. The easiest way to do that is tovisit the Docutils web site, download the source code, unpack it, andmove the docutils subdirectory (and all its contents) into our blogdirectory. When we later upload the application to GAE, the Docutils codewill get uploaded, too.
Docutils also looks for a roman.py file, which isn’t present inthe GAE Python environment. There’s one in the Google App Enginesource directory (which you downloaded); copy the roman.py filefrom there into the top directory of the blog.
Translation code
The code that actually translates RST to HTML is rather simple:
1 2 3 4 5 6 7 8 9 10 11 12 13 14
import os
from docutils.core import publish_parts
def rst2html(s):
settings = {'config' : None}
# Necessary, because otherwise docutils attempts to read a config file
# via the codecs module, which doesn't work with AppEngine.
os.environ['DOCUTILSCONFIG'] = ""
parts = publish_parts(source=s,
writer_name='html4css1',
settings_overrides=settings)
return parts['fragment']
The only wrinkle is the setting of the DOCUTILSCONFIG environmentvariable. I determined empirically that if you don’t set that variable toan empty string, the Docutils package attempts to read a startup file viathe codecs module, and the way it calls the codecs.open() methodconflicts with how that method is defined in the GAE Python library. (GAEhas replaced Python’s file handling routines with routines of its own, andthey’re not always 100% compatible.)
Store this code in file rst.py. We’ll then import it in our display code.
Create the Display Screens
Now we’re ready to create the display screens. There are six views to support:
Mainshows the topnarticles (wherenis the value ofMAX_ARTICLES_PER_PAGEin thedefs.pyfile). This screen is the main blog screen–the one a visitor sees first.
Show One Articleshows a single article. It’s used when someone clicks on the link for a single article.
Show Articles by Tagshows all articles with a specific tag.
Show Articles by Monthshows all articles in a specified month.
Show Archivelists the titles and dates of all articles in the blog.
Not Foundis a simple screen to display when an article or page isn’t found.
We’ll also add some query methods to the Article class as we go along.
Base Template
The simplest way to build these screens is to use Django templateinheritance, which has the additional benefit of ensuring a consistentlook. Most of the HTML goes into a base template. That template definesthe basic look and feel of the display pages, with various templatesubstitutions like and.
However, the base template also contains template code like the following:
1 2 3 4 5 6 7
<div id="articles_container">
{% for article in articles %}
{% block main %}
{% endblock %}
{% endfor %}
</div>
and this:

<div id="right-margin">
{% block recent_list %}
{% endblock %}
{% block date_list %}
{% endblock %}
</div>
The blocks can be filled in by other templates that inherit from this one.
blog.py
The handlers go in blog.py, which is similar to admin.py. There’s aninitialization section at the bottom that sets up the URL-to-handlermappings. Let look at that first:
1 2 3 4 5 6 7 8 9 10 11
application = webapp.WSGIApplication([('/', FrontPageHandler),
('/tag/([^/]+)/*$', ArticlesByTagHandler),
('/date/(\d\d\d\d)-(\d\d)/?$', ArticlesForMonthHandler),
('/id/(\d+)/?$', SingleArticleHandler),
('/archive/?$', ArchivePageHandler),
('/rss2/?$', RSSFeedHandler),
('/atom/?$', AtomFeedHandler),
('/.*$', NotFoundPageHandler),
],
debug=True)
AbstractPageHandler
At the top of the file, there’s a base class that consolidates a lot of thecommon logic. The most important method it contains is render_articles():
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51
class AbstractPageHandler(request.BlogRequestHandler):
def render_articles(self,
articles,
request,
recent,
template_name='show-articles.html'):
url_prefix = 'http://' + request.environ['SERVER_NAME']
port = request.environ['SERVER_PORT']
if port:
url_prefix += ':%s' % port
self.augment_articles(articles, url_prefix)
self.augment_articles(recent, url_prefix)
last_updated = datetime.datetime.now()
if articles:
last_updated = articles[0].published_when
self.adjust_timestamps(articles)
last_updated = self.adjust_timestamp(last_updated)
blog_url = url_prefix
tag_path = '/' + defs.TAG_URL_PATH
tag_url = url_prefix + tag_path
date_path = '/' + defs.DATE_URL_PATH
date_url = url_prefix + date_path
media_path = '/' + defs.MEDIA_URL_PATH
media_url = url_prefix + media_path
template_variables = {'blog_name' : defs.BLOG_NAME,
'blog_owner' : defs.BLOG_OWNER,
'articles' : articles,
'tag_list' : self.get_tag_counts(),
'date_list' : self.get_month_counts(),
'version' : '0.3',
'last_updated' : last_updated,
'blog_path' : '/',
'blog_url' : blog_url,
'archive_path' : '/' + defs.ARCHIVE_URL_PATH,
'tag_path' : tag_path,
'tag_url' : tag_url,
'date_path' : date_path,
'date_url' : date_url,
'atom_path' : '/' + defs.ATOM_URL_PATH,
'rss2_path' : '/' + defs.RSS2_URL_PATH,
'media_path' : media_path,
'media_url' : media_url,
'recent' : recent}
return self.render_template(template_name, template_variables)
This method takes:
a list of Articleobjects to be displayed
the original incoming HTTP request
a list of recent articles to display (which can be empty)
the template name to use, which defaults to the show-articles.htmltemplate
render_articles() then puts together the list of template variables,renders the specified template, and returns the result.
All the display handlers will use this method, which is why it resides in the base class.
Another method we should examine is augment_articles(), also in theAbstractPageHandler class:
1 2 3 4 5 6 7 8 9
def augment_articles(self, articles, url_prefix, html=True):
for article in articles:
if html:
try:
article.html = rst2html(article.body)
except AttributeError:
article.html = ''
article.path = '/' + defs.ARTICLE_URL_PATH + '/%s' % article.id
article.url = url_prefix + article.path
This method renders the HTML for each article to be displayed (if requested), and computes the article’s path and URL.
The base class also contains a few other methods used byrender_template():
get_tag_counts()assembles the list of unique tags, associating an article count with each one. It also determines which CSS class to associate with each tag, based on the tag’s relative frequency, for use when rendering the tag cloud; this information is returned in a list ofTagCountobjects. (TagCountis defined inblog.py. It’s not shown here.)
get_month_counts()returns a list ofDateCountobjects that the number of articles in each unique month/year.
get_recent()gets the most recent articles, making sure the list doesn’t exceed the maximum specified indefs.TOTAL_RECENT.
(See the complete file in the source code for details.)
Not Found Page
Next, let’s get the Not Found page out of the way. The templateis very simple:
1 2 3 4 5 6
{% extends "base.html" %}
{% block main %}
<p class="article_title">Not Found</p>
<p>Sorry, but there's no such page here.</p>
{% endblock %}
It extends the base template and fills in the main block with asimple static message. We’ll use this template in a couple places.
The NotFoundHandler class is also simple:
1 2 3 4 5 6
class NotFoundPageHandler(AbstractPageHandler):
def get(self):
self.response.out.write(self.render_articles([],
self.request,
[],
'not-found.html'))
Recall that this handler is the last, catch-all handler in the list of URLsin blog.py, so it’s automatically invoked if the incoming request doesn’tmatch any of the preceding URLs.
That’s all we have to do to install a custom “not found” handler.
Main Page
The main screen requires a template and a handler. With the base templateand the AbstractPageHandler class in place, both are pretty simple.Here’s the template, which resides in show-articles.html:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56
{% extends "base.html" %}
{% block main %}
{% for article in articles %}
{% include "article.html" %}
</td></tr></table>
{% endfor %}
{% endblock %}
{% block recent_list %}
{% if recent %}
<b>Recent:</b>
<ul>
{% for article in recent %}
<li><a href="{{ article.path }}">{{ article.title }}</a>
{% endfor %}
</ul>
{% endif %}
{% endblock %}
{% block date_list %}
{% if date_list %}
<b>By month:</b>
<ul>
{% for date_count in date_list %}
<li><a href="{{ date_path }}/{{ date_count.date|date:"Y-m" }}/">
{{ date_count.date|date:"F, Y" }}</a> ({{ date_count.count }})
{% endfor %}
</ul>
{% endif %}
{% endblock %}
{% block tag_list %}
{% if tag_list %}
<div id="tag-cloud">
{% for tag_count in tag_list %}
<a class="{{ tag_count.css_class }}"
href="{{ tag_path }}/{{ tag_count.tag }}/">
{{ tag_count.tag }}({{ tag_count.count }})</a>
{% if not forloop.last %},{% endif %}
{% endfor %}
</div>
{% endif %}
{% endblock %}
{% endraw}
{% endcodeblock %}
The template extends the base template, and then just fills in the
HTML for each block that's defined in the base template. Note, in
particular, this block:
{% codeblock %}
{% raw %}
{% for article in articles %}
{% include "article.html" %}
{% endfor %}
The actual template that displays an article resides in yet anotherfile, so it can be re-used in different templates.show-articles.html includes it, repeatedly, in a loop thattraverses the list of articles to be displayed.
The article.html template looks like this:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22
<table width="100%" border="0" cellspacing="0" cellpadding="0">
<tr class="article_title_line">
<td class="article_title">{{ article.title }}</td>
<td class="timestamp">
{{ article.published_when|date:"j F, Y \a\t g:i A" }}
</td>
</tr>
<tr>
{% if article.draft %}
<td colspan="2" class="article-body-draft">
{% else %}
<td colspan="2" class="article-body">
{% endif %}
{{ article.html }}
</td>
</tr>
<tr>
<td colspan="2" class="article-footer">
<a href="{{ article.path }}" class="reference">Permalink</a>|
Tags: {{ article.tags|join:", " }}</td>
</tr>
</table>
It’s relatively easy to understand: It assumes the existence of avariable called article that contains the article to bedisplayed.
The handler for the main page is even simpler:
1 2 3 4 5 6 7 8 9
class FrontPageHandler(AbstractPageHandler):
def get(self):
articles = Article.published()
if len(articles) > defs.MAX_ARTICLES_PER_PAGE:
articles = articles[:defs.MAX_ARTICLES_PER_PAGE]
self.response.out.write(self.render_articles(articles,
self.request,
self.get_recent()))
It gets the list of published articles, trims it down to the maximum number of articles on the main page, renders the articles to HTML, and dumps the result to the App Engine HTTP response object.
If you did not leave the dev_appserver running, bring it upagain. Then, connect to http://localhost:8080/, and check outyour main page. It should look something like this:
Show One Article
This screen shows a single article. It’s invoked when a readerselects a single post (e.g., http://www.example.org/blog/id/5).
It re-uses the same show-articles.html template, but with justone article in the list. The handler looks like this:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16
class SingleArticleHandler(AbstractPageHandler):
def get(self, id):
article = Article.get(int(id))
if article:
template = 'show-articles.html'
articles = [article]
more = None
else:
template = 'not-found.html'
articles = []
self.response.out.write(self.render_articles(articles=articles,
request=self.request,
recent=self.get_recent(),
template_name=template))
It attempts to retrieve the article with the specified ID. If thearticle exists in the database, then the code puts it in asingle-element list and tells render_articles() to use theshow_articles.html to display it.
If the article does not exist, the code uses the not-found.htmltemplate we defined earlier to display the generic “not found”screen.
Note that this version of the get() method accepts an idparameter. Where does that come from? Recall the configuration forthis handler in the WSGIApplication object at the bottom of thescript:
1 2 3 4 5 6 7
application = webapp.WSGIApplication(
[ ...
('/id/(\d+)/?$', SingleArticleHandler),
...
],
Note that the regular expression, '/id/(\d+)/?$ contains a group,(\d+). Like Django, GAE maps each group into a parameter to the get()or post() method. In this case, the string that matches the regularexpression group (the article’s numeric ID, in this case) is passed as thefirst parameter to the get() method.
Show Articles By Tag
The ArticlesByTagHandler class again re-uses the show-articles.htmltemplate:
1 2 3 4 5 6
class ArticlesByTagHandler(AbstractPageHandler):
def get(self, tag):
articles = Article.all_for_tag(tag)
self.response.out.write(self.render_articles(articles,
self.request,
self.get_recent()))
Note, however, that it’s calling a class method calledall_for_tag() in the Article class. We have to extend Articleto support this query method. That method turns out to be trivial:
1 2 3 4 5 6
@classmethod
def all_for_tag(cls, tag):
return Article.published_query()\
.filter('tags = ', tag)\
.order('-published_when')\
.fetch(FETCH_THEM_ALL)
My original version of this method loaded all published articles and manually searched through their tags. However, in an email to the Google App Engine mailing list, Bill Katz pointed me to something I missed in the GAE docs:
In a query, comparing a list property to a value performs the test against the list members:
list_property = valuetests if the value appears anywhere in the list.
This is convenient and more efficient than my original solution.
Show Articles By Month
By now, you should be getting the hang of this.
Next, we have to write a handler that’ll produce a page of posts for a given month. As with the tag handler, the month handler is trivial:
1 2 3 4 5 6
class ArticlesForMonthHandler(AbstractPageHandler):
def get(self, year, month):
articles = Article.all_for_month(int(year), int(month))
self.response.out.write(self.render_articles(articles,
self.request,
self.get_recent()))
Again, though, it calls an Article class method we have yet to write:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15
@classmethod
def all_for_month(cls, year, month):
start_date = datetime.date(year, month, 1)
if start_date.month == 12:
next_year = start_date.year + 1
next_month = 1
else:
next_year = start_date.year
next_month = start_date.month + 1
end_date = datetime.date(next_year, next_month, 1)
query = Article.published_query()\\
.filter('published_when >=', start_date)\\
.filter('published_when <', end_date)\\
.order('-published_when')
return query.fetch(FETCH_THEM_ALL)
This method chains query filters to the query returned byArticle.published_query(). The filters ensure that the returned articlesare the ones published within the specified year and month.
Show Archive
This page shows the titles of all published articles, in reverse chronological order. I chose to make this page even simpler than the other pages: It lacks the tag cloud, recent posts, and posts-by-month sections in the margin. The template is trivial:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15
{% extends "base.html" %}
{% block main %}
<span class="heading">Complete Archive:</span>
{% if articles %}
<ul>
{% for article in articles %}
<li><a href="{{ article.path }}">{{ article.title }}</a>
({{ article.timestamp|date:"j F, Y" }})
{% endfor %}
</ul>
{% else %}
<p>This blog is empty. (Someone want to fix that?)
{% endif %}
{% endblock %}
And the handler is, once again, trivial:
1 2 3 4 5 6 7
class ArchivePageHandler(AbstractPageHandler):
def get(self):
articles = Article.published()
self.response.out.write(self.render_articles(articles,
self.request,
[],
'archive.html'))
Note that ArchivePageHandler passes an empty list for the “recent” posts(since it won’t be used) and the archive template.
Here’s what the archive page looks like with our two articles in the archive:
RSS Feed
Any decent blog supplies an RSS feed, so we should do that, too. Of course, that’s simply a matter of writing a template and a small handler. By now, the handler should look pretty familiar:
1 2 3 4 5 6 7 8
class RSSFeedHandler(AbstractPageHandler):
def get(self):
articles = Article.published()
self.response.headers['Content-Type'] = 'text/xml'
self.response.out.write(self.render_articles(articles,
self.request,
[],
'rss2.xml'))
The template is simple, too:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21
<?xml version="1.0" encoding="utf-8" ?>
<rss version="2.0" xmlns:dc="http://purl.org/dc/elements/1.1/">
<channel>
<title>{{ blog_name }}</title>
<link>{{ blog_url }}</link>
<description>{{ blog_name }}</description>
<pubDate>{{ last_updated|date:"D, d M Y H:i:s T" }}</pubDate>
{% for article in articles %}
<item>
<title>{{ article.title }}</title>
<link>{{ article.url }}</link>
<guid>{{ article.url }}</guid>
<pubDate>{{ article.timestamp|date:"D, d M Y H:i:s T" }}</pubDate>
<description>
{{ article.html|escape }}
</description>
<author>{{ blog_author }}</author>
</item>
{% endfor %}
</channel>
</rss>
Deploy the Application
Test the application using dev_appserver; when you think it’sready, it’s time to deploy it. From within the blog’s top-levelsource directory, run this command:
appcfg.py update .
That’ll upload your application to your Google App Engine account.If the application name is picoblog, then your live applicationwill appear at http://picoblog.appspot.com/.
Handling Static Files such as Images
Of course, a blog should be able to display images. Since our newblog software doesn’t support image upload, how can we use images?The answer is simple, if slightly clunky: Put any images you wantto use in your picoblog/static directory. Then, use appcfg.pyto update the live application; appcfg.py will copy those imagesup to the Google App Engine server, where you can use them.
For instance, assume you have a picture call foo.png that youwant to use in a blog article. Here’s how you might deploy it:
1 2 3
$ cd picoblog
$ cp ~/foo.png static
$ appcfg.py update .
Then, you can use the reStructuredText .. image directive to pullit into an article:
.. image:: /static/foo.pn
:width: 180
:height: 150
Previewing a Draft
There’s one last feature to add: The ability to preview a draft article without publishing it.
With this software in place, you can already do that by using aseparate browser window or frame. For instance, suppose you’reediting a new article, and its ID happens to be 53. In anotherwindow, you can surf to that ID directly, using the URLhttp://picoblog.appspot.com/id/53/.
But it might also be nice to preview the article in the same window where you’re doing your editing. That turns out to be trivial to implement: Merely go back to `The Edit Screen Template`_, and add these lines right after the end of the form:
1 2 3 4
<h1 class="admin-page-title">Preview:</h1>
<div style="border-top: 1px solid black">
<iframe src="/id/{{ article.id }}" width="97%" scrolling="auto" height="750" frameborder="0">
</iframe>
Now, you’ll always have a preview frame underneath the edit controls.
Enhancements
Now that you have the basic blog in place, you can start to add other enhancements, such as:
Support for Pygments syntax coloring.
Support for Google Analytics, which is useful for analyzing logs and traffic.
Image uploading.
A more individual theme.
etc.
In Closing
In this (long) tutorial, we built a simple blog using Python and Google’s App Engine. The code represented in this article is very similar to the code that runs this very blog; it’s certainly effective, even if it lacks certain bells and whistles right now. With any luck, you now have a better understanding of what it means to build an application on App Engine.
Feedback
I welcome feedback. Feel free to submit a comment, below, or drop me an email with comments or corrections. I’ll update this article with any good stuff I receive.

Manipulating sys.modules
You can manipulate the modules cache directly, making modules available or unavailable as you wish:
>>> import sys
>>> import ham
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: No module named ham
# Make the 'ham' module available -- as a non-module object even!
>>> sys.modules['ham'] = 'ham, eggs, saussages and spam.'
>>> import ham
>>> ham
'ham, eggs, saussages and spam.'
# Now remove it again.
>>> sys.modules['ham'] = None
>>> import ham
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: No module named ham
This works even for modules that are available, and to some extent for modules that already are imported:
>>> import os
# Stop future imports of 'os'.
>>> sys.modules['os'] = None
>>> import os
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: No module named os
# Our old imported module is still available.
>>> os
<module 'os' from '/usr/lib/python2.5/os.pyc'>
As the last line shows, changing sys.modules only affects future import statements, not past ones, so if you want to affect other modules it's important to make these changes before you give them a chance to try and import the modules -- so before you import them, typically. None is a special value in sys.modules, used for negative caching (indicating the module was not found the first time, so there's no point in looking again.) Any other value will be the result of the import operation -- even when it is not a module object. You can use this to replace modules with objects that behave exactly like you want. Deleting the entry from sys.modules entirely causes the next import to do a normal search for the module, even if it was already imported before. |

Re : [HOW TO] adesklets : configuration des desklets
J'allais le dire. Je n'ai pas retesté les nouvelles versions de gdesklets, mais à l'époque de l'écriture du tuto, il n'y avait pas photo. Le principal atout de adesklets est à mon avis la consommation des ressources. Le seul petit défaut est qu'il faut un petit peu plus de temps pour l'appréhender, mais le résultat en vaut la peine et c'est un plaisir pour les bidouilleurs .

Re : [HOW TO] adesklets : configuration des desklets
Donc au fait, j'ai constaté que le le desklets se lance au démarrage, apparaît, ensuite le bureau et les icones apparaissent a leur tour masquant ainsi le desklet.
Et lorsque j'arrete ma session, l'environnement graphique s'arrete et le programme est toujours bien là. Il s'arrete ensuite a son tour.
C'est comme si le desklets se trouvait dérrière l'arrière plan de mon bureau, non pas l'inverse
Le fichier config.txt, c'est celui de weatherforcecast que tu souhaites?
Qu'est ce que la console de lancement ?
Je suis sous linux depuis 5 jours ^^ seulement

Salut,
je pense que le soucis est que lorsque tu as compilé adesklets, tu n'as pas passé l'option --enable-legacy-fake-root-window-detection lors du ./configure (cf : http://forum.ubuntu-fr.org/viewtopic.php?id=19135&p=1).

Re : [HOW TO] adesklets : configuration des desklets
Pour le désinstaller, fais :
cd adeklets-0.5.0
sudo make uninstall
Sinon, tu peux aussi essayer de lancer de cette manière :
adesklets --nautilus

Re : [HOW TO] adesklets : configuration des desklets
Bon j'ai désinstallé et réinstaller, il se lance et se positionne au bon endroit.
Mais la transparence n'y est pas, le transparent est remplacé par une case noir. Comment dois-je faire pour la transparence au lieu du noir. C'est weatherforecast
J'ai lancer systemmonitor, mais il ne tourne pas lorsque je test. Comment dois je faire ?
Voilà j'ai terminé mes questions pour le moment.
Encore merci pour votre aide

Ah, c'est étrange alors. Tu n'as rien de particulier dans ta configuration ?
Pour System Monitor, tu as correctement installé libstatgrab et pystatgrab ?

Phoen1x,
J'avais la même erreur au début :

Il trouve pas la police de caractère VeraBd...
Donc, tu vas dans le config.txt du system monitor, et tu remplace tout les VeraBd par Vera
Normalement cette police là il l'a trouve bien...
Après moi ca fonctionnait, javais plus cette erreur.

Using Python PIL, I'm trying to adjust the hue of a given image.
I'm not very comfortable with the jargon of graphics, so what I mean by âadjusting hueâ is doing the Photoshop operation called âHue/saturationâ: this is to change the color of the image uniformly as shown below:
Original:
With hue adjusted to +180 (red):
With hue adjusted to -78 (green):
FYI, Photoshop uses a scale of -180 to +180 for this hue setting (where -180 equals +180), that may represents the HSL hue scale (expressed in 0-360 degree).
What I'm looking for is a function that, given an PIL image and a float hue within [0, 1] (or int within [0, 360], it doesn't matter), returns the image with its hue shifted by hue as in the example above.
What I've done so far is ridiculous and obviously doesn't give the desired result. It just half-blend my original image with a color-filled layer.
import Image
im = Image.open('tweeter.png')
layer = Image.new('RGB', im.size, 'red') # "hue" selection is done by choosing a color...
output = Image.blend(im, layer, 0.5)
output.save('output.png', 'PNG')
(Please-don't-laugh-at-) result:
Thanks in advance!
Solution: here is the unutbu code updated so it fits exactly what I've described.
import Image
import numpy as np
import colorsys
rgb_to_hsv = np.vectorize(colorsys.rgb_to_hsv)
hsv_to_rgb = np.vectorize(colorsys.hsv_to_rgb)
def shift_hue(arr, hout):
r, g, b, a = np.rollaxis(arr, axis=-1)
h, s, v = rgb_to_hsv(r, g, b)
h = hout
r, g, b = hsv_to_rgb(h, s, v)
arr = np.dstack((r, g, b, a))
return arr
def colorize(image, hue):
"""
Colorize PIL image `original` with the given
`hue` (hue within 0-360); returns another PIL image.
"""
img = image.convert('RGBA')
arr = np.array(np.asarray(img).astype('float'))
new_img = Image.fromarray(shift_hue(arr, hue/360.).astype('uint8'), 'RGBA')
return new_img

I'm using Cloud9 (which from what I've read uses Python 2.6 currently, not Python 3) to write a Django app. I'm trying to read a CSV file with DictReader and use each column in the CSV to create a new instance of a model and populate the model fields.
views.py
class GenerateFromCSV(CreateView):
model = group
template_name = "my_app/csv_generate.html"
def form_valid(self, form):
new_group = form.save()
the_csv = open(new_group.group_csv, 'rbU')
fieldnames = ['c_type', 'f_name', 'q_type', 'ans', 'n_questions', 'bucket']
data_file = csv.DictReader(the_csv, fieldnames = fieldnames, delimiter=',', dialect=csv.excel)
for row in data_file:
new_card = Card(
name = 'card',
card_type = row['c_type'],
file_name = row['f_name'],
question_type = row['q_type'],
answer = row['ans'],
num_questions = row['n_questions'],
bucket = row['bucket'],
exam = new_exam)
new_card.save()
models.py
class Group(models.Model):
name = models.CharField(max_length=255, blank = True)
subject = models.CharField(max_length=255, choices = SUBJECT, blank = True)
num_questions = models.IntegerField(default=0, blank = True, null = True)
group_csv = models.FileField(upload_to='csv', blank = True, null = True)
def __unicode__(self):
return self.name
class Card(models.Model):
name = models.CharField(max_length=255, blank = True)
#ordered same as column order in CSV
card_type = models.CharField(max_length=255, choices = CARDTYPE, blank = True)
file_name = models.CharField(max_length=255, blank = True)
question_type = models.IntegerField(default = 0, blank = True, null = True)
answer = models.IntegerField(max_length = 1, choices = ANSWERS, blank = True, null = True)
num_questions = models.IntegerField(default = 0, blank = True, null = True)
bucket = models.CharField(max_length=255, blank = True)
exam = models.ForeignKey(Exam)
def __unicode__(self):
return self.name or 'card'
With the code as it is above, I get a TypeError (coercing to Unicode: need string or buffer, FieldFile found) when I call open() on the CSV. If I remove the call to open(), I get the error: 'new-line character seen in unquoted field - do you need to open the file in universal-newline mode?'
My CSV is in the format (not every column contains data in every row):
3,the_file_name.png,0,"00001",,Equations
What is the correct syntax for this?

What is the criteria by which you'll be judging whether it's feasible or not?
It certainly is possible. The QProcess class provides everything that you would need for running and interacting with external processes inside a Qt application. At its core, it can do everything that subprocess can do (albeit, less conveniently). Here's a contrived usage example:
button = QPushButton('start')
textedit = QTextEdit()
process = QProcess()
button.clicked.connect(on_clicked)
def on_clicked():
process.readyReadStandardOutput.connect(read_ready)
process.start('/bin/sh',
('-c', "while /bin/true; do echo hello world ; sleep 1; done"))
def read_ready(self):
chunk = process.readAllStandardOutput()
textedit.append(str(chunk))
Since you're still at the planning stage, why not consider a tool such as zenity for the GUI part? It could save you a lot of work. Getting a list of checkboxes and sending the output of a command to a textarea becomes a matter of:
parameters=$(
zenity --list --text "Test parameters:" \
--checklist --column "Check" --column "Parameter" \
TRUE "One" TRUE "Two" TRUE "Three" FALSE "Four" \
--separator=":");
# parameters -> One:Two:Three
./instrument-test.py $parameters | zenity --text-info
Best of luck with your project! |
I have an Atom feed generator for my blog, which runs on AppEngine/Python. I use the Django 1.2 template engine to construct the feed. My template looks like this:
<?xml version="1.0" encoding="utf-8"?>
<feed xmlns="http://www.w3.org/2005/Atom"
xml:lang="en"
xml:base="http://www.example.org">
<id>urn:uuid:4FC292A4-C69C-4126-A9E5-4C65B6566E05</id>
<title>Adam Crossland's Blog</title>
<subtitle>opinions and rants on software and...things</subtitle>
<updated>{{ updated }}</updated>
<author>
<name>Adam Crossland</name>
<email>adam@adamcrossland.net</email>
</author>
<link href="http://blog.adamcrossland.net/" />
<link rel="self" href="http://blog.adamcrossland.net/home/feed" />
{% for each_post in posts %}{{ each_post.to_atom|safe }}
{% endfor %}
</feed>
Note: if you use any of this, you'll need to create your own uuid to go into the id node.
The updated node should contain the time and date on which contents of the feed were last updated in rfc 3339 format. Fortunately, Python has a library to take care of this for you. An excerpt from the controller that generates the feed:
from rfc3339 import rfc3339
posts = Post.get_all_posts()
self.context['posts'] = posts
# Initially, we'll assume that there are no posts in the blog and provide
# an empty date.
self.context['updated'] = ""
if posts is not None and len(posts) > 0:
# But there are posts, so we will pick the most recent one to get a good
# value for updated.
self.context['updated'] = rfc3339(posts[0].updated(), utc=True)
response.content_type = "application/atom+xml"
Don't worry about the self.context['updated'] stuff. That just how my framework provides a shortcut for setting template variables. The import part is that I encode the date that I want to use with the rfc3339 function. Also, I set the content_type property of the Response object to be application/atom+xml.
The only other missing piece is that the template uses a method called to_atom to turn the Post object into Atom-formatted data:
def to_atom(self):
"Create an ATOM entry block to represent this Post."
from rfc3339 import rfc3339
url_for = self.url_for()
atom_out = "<entry>\n\t<title>%s</title>\n\t<link href=\"http://blog.adamcrossland.net/%s\" />\n\t<id>%s</id>\n\t<summary>%s</summary>\n\t<updated>%s</updated>\n </entry>" % (self.title, url_for, self.slug_text, self.summary_for(), rfc3339(self.updated(), utc=True))
return atom_out
That's all that is required as far as I know, and this code does generate a perfectly-nice and working feed for my blog. Now, if you really want to do RSS instead of Atom, you'll need to change the format of the feed template, the Post template and the content_type, but I think that is the essence of what you need to do to get a feed generated from an AppEngine/Python application. |
After you've made your .scheme or .schemedef file (see Add Support for Your Language) there's still something missing from that authentic professional feeling when programming with your newly defined language. For that you need to create an auto-indenter.
Please note: You need to have PyPN installed for this to work! See Install PyPN for further instructions.
To create an auto-indenter you must make a new Python script that PN recognizes as an indenter. Throughout this tutorial I'm going to use The Elder Scrolls scripting language for Oblivion as an example (_here should be tes.schemedef file but the site don't allow me to upload it_). More information about it can be found at http:_cs.elderscrolls.com/constwiki/index.php/Portal:Scripting.
Every auto-indenter must import at least the following (in most cases these are enough too):
import scintilla from pypn.decorators import indenter
After the imports we define the indenter function. Let's see the start of that definition from the example before further explanation:
@indenter("tes") def tes_indent(c, doc):
The first line tells PyPN that the following function is meant to be an indenter. The string in parentheses must match the name of the scheme or schemedef of the language we're trying to indent. The second line is regular Python. You can name the function what ever you like but descriptive names like ''tes_indent'' have advantages. The function must have two parameters - their naming doesn't matter but as PyPN already uses ''c'' and ''doc'' for them there's no reason to change.
In Oblivion scripts the indentation is made by keywords. There are few keywords that start a block that gets indented and there are other keywords that end such blocks and cause unindentation. Easiest way to define them in Python is to use a list. I find it best to define these outside of the function.
# Keywords that cause indentation. i_kws = ['scriptname', 'scn', 'begin', 'if', 'elseif'] # Keywords that cause unindentation. u_kws = ['end', 'endif']
Lines starting with ''#'' are Python comments. Variable names are again inconsequential - just use what you consider descriptive. In Python lists are surrounded by brackets and list items are separated by commas. As Oblivion scripts are not case-sensitive it's easiest to type the keywords in lowercase.
People like different tabwidths for indentation and such preferences often vary from language to language. To ease that we define one more variable before we move on to function itself (I've used tabwidth of two because that's how most of the code in their Wiki is indented but in most cases I'd prefer four):
# Tabwidth used for indentation. tab = 2
To be able to auto-indent we need quite a bit of data from our document. Depending on how your language is indented you may need more or less than we do in our example but you should get the idea. Let's have the next bit of code before further explanation (I've included some of the stuff from earlier so that you know where to place this):
@indenter("tes") def tes_indent(c, doc): sci = scintilla.Scintilla(doc) pos = sci.CurrentPos l_cur = sci.LineFromPosition(pos) t_start = sci.PositionFromLine(l_cur - 1) t_end = pos - 1 txt = sci.GetText(t_start, t_end) kw = txt.split()[0].lower()
In almost every PyPN script we a have variable that is set to ''scintilla.Scintilla(doc)'' (or more often actually ''scintilla.Scintilla(pn.CurrentDoc())''). We need it to use Scintilla's functions through PyPN.
For our needs we need to know the following about our document:
With this information at hand we can move on.
First, let's figure out what we're trying to do. Here's the logic in pseudo language:
if [first word on previous line] == [a block starting keyword] -> indent current line elseif [first word on previous line] == [a block ending keyword] -> unindent previous and current line
So obviously we're going to need some if statements. Let's see some code before further explanation:
if kw in i_kws: c_ind = sci.GetLineIndentation(l_cur) p_ind = sci.GetLineIndentation(l_cur-1) if c_ind == p_ind or c_ind == 0: c_ind += tab sci.IndentLine(l_cur, c_ind)
This is the if clause for indentation. First we check if the word ''kw'' is among those that start an indented block. Then we get the indentation levels for current and previous line with ''sci.GetLineIndentation()'' and check that either both lines are equally indented or that the current line is not indented at all. If either of these is correct current line is indented by the amount defined in our variable ''tab''.
elif kw in u_kws: c_ind = sci.GetLineIndentation(l_cur) p_ind = sci.GetLineIndentation(l_cur-2) if c_ind == p_ind: c_ind -= tab sci.IndentLine(l_cur, c_ind) sci.IndentLine(l_cur-1, c_ind)
Code for unindentation is very similar. Most notable differences are that we unindent both current and previous line, and due to that we use the line before previous when comparing indentation levels of lines (otherwise we'd unindent twice on Windows where EOL is marked by ''\n\r''). Also ''kw'' is obviously searched from the list containing block ending keywords.

With the current lack of documentation and some bugs in PyPN creating scripts is often about learning from errors. I used the Python indenter that comes with PyPN as a some sort of a starting point (I must notify that there is a redundant piece of code in that one - there is no need to check if the character is EOL as that's already done in ''pypn.glue''). PN source code and Scintilla documentation were also essential. I hope someone finds this useful. |
Building on the answer given above with the single line Tree using defaultdict, you can make it a class. This will allow you to set up defaults in a constructor and build on it in other ways.
class Tree(defaultdict):
def __call__(self):
return Tree(self)
def __init__(self, parent):
self.parent = parent
self.default_factory = self
This example allows you to make a back reference so that each node can refer to its parent in the tree.
>>> t = Tree(None)
>>> t[0][1][2] = 3
>>> t
defaultdict(defaultdict(..., {...}), {0: defaultdict(defaultdict(..., {...}), {1: defaultdict(defaultdict(..., {...}), {2: 3})})})
>>> t[0][1].parent
defaultdict(defaultdict(..., {...}), {1: defaultdict(defaultdict(..., {...}), {2: 3})})
>>> t2 = t[0][1]
>>> t2
defaultdict(defaultdict(..., {...}), {2: 3})
>>> t2[2]
3
Next, you could even override __setattr__ on class Tree so that when reassigning the parent, it removes it as a child from that parent. Lots of cool stuff with this pattern. |

Re : erreur avec apache2 : « Unable to open logs » [RESOLU]
non non je sais faire les serveur sans interface j'ai fait sa surtout pour simplifier après non je ne suis pas tout a lettre car le tuto que j'ai suivi avait des erreurs pour certaine chose surtout pour c'est source pas bonne j'ai du aller sur le site officier entre deux ainsi que pour les source j'ai suivi le tuto juste parce qu'il été plus claire et en français mais je voulais savoir comment il a pus m'infecté mon serveur car pendant quelque moi j'ai eu aucun souci

Re : erreur avec apache2 : « Unable to open logs » [RESOLU]
je voulais savoir comment il a pus m'infecté mon serveur car pendant quelque moi j'ai eu aucun souci
As-tu bien maintenu ispconfig à jour en installant toutes les version qui sortaient au fur et à mesure ?
As-tu bien maintenu les paquets Ubuntu à jour dès la sortie d'une mise à jour ?
As-tu bien veillé à ce qu'aucun mot de passe lié à ce serveur ne transite en clair, même une fois (j'ai déjà la réponse : c'est non, vu que tu as du FTP, du POP et de l'IMAP) ?
As-tu bien veillé à ce qu'un tel mot de passe ne soit jamais utilisé sur un réseau non sécurisé (wifi public par exemple) ?
As-tu bien veillé à ne pas installer de clé SSH provenant de comptes potentiellement corrompus ?
Tout ça (et bien plus) ça peut être des sources de piratage.
Allez, au pif : tu avais un serveur FTP, donc des gens (toi ?) se connectaient en FTP, donc des mots de passe transitaient en clair. Si un seul de ces mots de passe est intercepté par quelqu'un (sur un wifi public, par exemple, c'est hyper facile) alors ce quelqu'un aura accès à ton serveur. Et si jamais le mot de passe en question est celui d'un compte administrateur, bingo !
Tu avais aussi un MDA (Courier). Les mots de passe transitaient-ils en clair ? Si oui, même punition.

Vu qu'apache semble en avoir pris plein la poire (virtual host skynet ...) je commencerai par les logs d'apache et du système... Mais ceux-ci seront probablement détruits lors de la réinstallation.

----------------------------
Hello abuse address for 46.17.97.111,
The host at 46.17.97.111 seems to be infected with a worm.
I believe that this is the case because over here at love.zweije.nl,
I am receiving inexplicable TCP connect requests from that host.
An extract from my system log (timezone +0100) is attached.
Please ensure that the maintainer of 46.17.97.111 cleans up his host.
Thank you. Vincent.

"could not open error log file"
Ca veut quand meme bien dire ce que ca veut dire non ? apache n'arrive pas à ouvrir (ni même à créer je dirai) son fichier de log. Ce qui n'est pas surprenant puisque :
-rw-r--r-- 1 root root 0 Jan 30 23:08 /var/log/apache2
Donc que seul root peut ecrire dedans, alors que je suppose que c'est l'utilisateur www-data qui dois essayer de créer le fichier.
Bref, la première chose que je vérifierai moi, ce sont les droits du répertoire /var/log et /var/log/apache2, parce qu'on dirait qu'il y a eu des trucs pas très net de fait de ce coté la.

-rw-r--r--1 root root 0 Jan 30 23:08 /var/log/apache2
Et comme je l'ai fait résoudre dans le message #8 :

mkdir /var/log/apache2
Le répertoire en question a été "transformé" en fichier (pas de "d" au début de la ligne de retour du "ld").
Vu le message suivant :

Le problème c'est que la suite logique ce sera forcément "vieux con", et la c'est sur, je vais mal le prendre
Tu cherches à trouver une cause déjà trouvée
En effet.
Bien la preuve que je suis effectivement déjà devenu vieux... Et merde

I want the images to change (rotate) in sequence when the page is refreshed not random like i have below. Can someone help me with this please? Also I also need text to change on refresh to because I am going to have a descritption of the image below.

Is that when one person refreshes the same page?
How about when you have more than one visitor to the page. Do you want them all to start with seeing image number 1, or do you want the image sequence to be spread across all visitors.
paul_wilkins — 2011-05-26T21:18:42-04:00 — #3
It seems then that using cookies to remember which was the last image to be shown to the visitor, could be an appropriate way to go.
Any client-side solution is guaranteed to fail when javascript is not available though, so using a server-side script such as PHP or ASP is a preferred solution for this type of thing.
twistidphreak — 2011-05-26T21:02:50-04:00 — #4
Either a new visitor or when they refresh because I am going to have a text description of the each image that needs to be in the same order with the image so they are in sync. |
Lets say I want to set up a basic text encoding using a dictionary in python.
Two ways of doing this come to mind immediately - using zip, and using list comprehension.
characters = "ABCDEFGHIJKLMNOPQRSTUVWXYZ .,!;"
dict_a = dict((x, characters[x]) for x in xrange(0, 31))
dict_b = dict(zip(xrange(0, 31), characters))
Which of these is more efficient? (The real encoding is longer than 31, this is a toy example). Is the difference significant?
Alternatively, am I approaching this wrong and should be using something other than a dictionary? (I need to be able to go in both directions of encoding). |
I am writing code that will search twitter for key words and store them in a python dictionary:
base_url = 'http://search.twitter.com/search.json?rpp=100&q=4sq.com/'
query = '7bOHRP'
url_string = base_url + query
logging.info("url string = " + url_string)
json_text = fetch(url_string)
json_response = simplejson.loads(json_text.content)
result = json_response['results']
print "Contents"
print result
The resulting dictionary is :
Contents[{
u 'iso_language_code': u 'en',
u 'text': u "I'm at Cafe en Seine (40 Dawson Street, Dublin) w/ 2 others. http://4sq.com/7bOHRP",

How can I access the 'from_user' and what is the 'u' before the key and value? |
I have a numpy master array. Given another array of search values, with repeating elements, I want to produce the indices of these search values in the master array.
E.g.: master array is [1,2,3,4,5], search array is [4,2,2,3]
Solution: [3,1,1,2]
Is there a "native" numpy function that does this efficiently (meaning at C speed, rather than python speed)?
I'm aware of the following solution, but, first, it's a python list comprehension, and second, it'll search for the index of 2 twice.
ma = np.array([1,2,3,4,5])
sl = np.array([4,2,2,3])
ans = [np.where(ma==i) for i in sl]
Also, if I have to resort to sorting and binary search, I will do it as a last resort (puns not intended at all sorts of levels). I am interested in finding if I'm missing something basic from the numpy library. These lists are very large, so performance is paramount.
Thanks.
Edit: Before posting I'd tried the following with dismal results:
[np.searchsorted(ma,x) for x in sl]
The solution posted by @pierre is much more performant and exactly what I was looking for. |
The following regular expression:
^\[([^\]]+)\]
will capture the date at the beginning of the string plus square brackets, and will put the stuff in between the square brackets into a group that can be extracted by itself.
Note that your text editor may have a slightly different syntax. Here's how this breaks down:
^ = beginning of line/string
\[, \] = literal [ and ] characters
() = signifies a group to capture
[^\]] = matches any character _except_ a close bracket
(this keeps the match from being too greedy)
+ = one or more of the previous
EDIT: This assumes your regex facility supports groups (which most do). The easiest way to explain groups is just to show you how they work with one such engine. In the Python interpreter:
>>> import re
>>> s = '[2010-01-15 06:18:10.203] [0x00001388] [SHDNT] ...'
>>> r = re.compile(r'^\[([^\]]+)\]')
>>> m = r.search(s)
This creates a regular expression object and searches the string for the first set of text that matches it. The result is returned in a match object:
>>> m
<_sre.SRE_Match object at 0x1004d9558>
To get the entire set of text that was matched, the Python convention is to invoke group() on the match object:
>>> m.group()
'[2010-01-15 06:18:10.203]'
and to get just the stuff in parentheses, I pass the number of the group I want (in this case there's just one set of parens, so just one group):
>>> m.group(1)
'2010-01-15 06:18:10.203'
If I perform a replace instead of a search, I use the sub function. Sub takes the string I want to replace the full match by, followed by the input string, and returns the string with the replacement performed if a match was found:
>>> r.sub('spam spam spam', s)
'spam spam spam [0x00001388] [SHDNT] ...'
However, the replacement string supports escape sequences that refer to specific values of groups captured by the match. A group substitution is indicated by \N, where N is the number of the group. Hence:
>>> r.sub(r' \1 ', s)
' 2010-01-15 06:18:10.203 [0x00001388] [SHDNT] ...'
which is what you want. |
You can script something like this:
import trac.admin.console
import trac.config
import os
def _get_project_options(envdir):
confpath = os.path.join(envdir, 'conf/trac.ini')
config = trac.config.Configuration(confpath)
return dict([x for x in config.options(u'project')])
def _get_project_name(envdir):
admin = trac.admin.console.TracAdmin(envdir)
if admin.env_check():
options = _get_project_options(envdir)
return options[u'name']
else:
return None
def iter_trac_projects_from_dir(dirname):
for which in os.listdir(dirname):
if not which in ('.', '..') and os.path.isdir(dirname):
envdirname = os.path.join(dirname, which)
project_name = _get_project_name(envdirname)
if project_name:
yield (project_name, envdirname)
def get_trac_projects_from_dir(dirname):
return [pr for pr in iter_trac_projects_from_dir(dirname)]
Then you can use either iter_trac_projects_from_dir or get_trac_projects_from_dir whichever you think is best for you.
Alternatively you could use the function get_enviroments from module trac.web.main but only as alternative to os.listdir -- you would still have to check whether or not each alleged env is really a trac environment. See why:
>>> import trac.web.main
>>> env = {'trac.env_parent_dir':
... '/home/manu/tmp'}
>>> trac.web.main.get_environments(env)
{'test': '/home/manu/tmp/test', 'no-a-real-trac-project': '/home/manu/tmp/no-a-real-trac-project', 'test2': '/home/manu/tmp/test2'}

I'm an admittedly pretty basic Python programmer, trying to learn as I encounter problems implementing various research problems. And I've hit one of those problems - particularly, how to handle loops where I'm returning a bunch of data, rather than the usual "out comes a single number" examples where you just add the result of the loop to everything previous.
Here's a Gist of the unlooped script I'm trying to run: https://gist.github.com/1390355
The really salient point is the end of the model_solve function:
def model_solve(t):
# lots of variables set
params = np.zeroes((n_steps,n_params)
params[:,0] = beta
params[:,1] = gamma
timer = np.arange(n_steps).reshape(n_steps,1)
SIR = spi.odeint(eq_system, startPop, t_interval)
output = np.hstack((timer,SIR,params))
return output
That returns the results of the ODE integration bit (spi.odeint) along with a simple "What time step are we on?" timer and essentially two columns of the value of two random variables repeated many, many times in the form of 4950 row and 7 column NumPy array.
The goal however is to run a Monte Carlo analysis of the two parameters (beta and gamma) which have random values. Essentially, I want to make a function that loops somewhat like so:
def loop_function(runs):
for i in range(runs):
model_solve(100)
# output of those model_solves collected here
# return collected output
That collected output would then be written to a file. Normally, I'd just have each model_solve function write its results to a file, but this code is going to be run on PiCloud or another platform where I don't necessarily have the ability to write a file until the results are returned to the local machine. Instead, I'm trying to get a return of a huge NumPy array of runs*7 columns and 4950 rows - which can then be written to a file on my local machine.
Any clues as to how to approach this? |

moi c'est le contraire, mais je crois que météo France auras plus pour vocation de test qu'autre chose (il me fatigue à modifier le nombre d'info toutes la journée).
Je vais voir ce que je peut faire avec un site plus contant dans sont nombres d'infos journalière, ce sera certainement previmeteo.com car après tous, ils nous propose plein de façon différent de récupérer les infos météo.

Re : [Conky] Alternative à weather.com ( icones conkyforecast )
Me revoilà de retour sur les ondes.
Tout d'abord un grand bravo à Didier-T et Levi59 pour le travail effectué sur les scripts.
N'étant pas en mesure moi-même de faire grand chose sur les scripts, je me contente donc de tester et de faire part de mes remarques afin de les perfectionner ou les modifier.
Tout d'abord une petite impression d'écran pour expliciter les 2 bugs que je rencontre :1/ Affichage des icônes du vent
Comme je l'ai déjà indiqué, lorsque je lance le conky en terminal, j'ai régulièrement un message d'erreur du genre :
cp: la cible «/home/gilles/conky/meteo/images/conky/v1.png» n'est pas un répertoire
cp: la cible «/home/gilles/conky/meteo/images/conky/v4.png» n'est pas un répertoire
Ce qui se traduit par le fait que les icônes du vent qui déclenchent ce message d'erreur ne sont pas actualisées. Du coup, nous avons des icônes qui ne correspondent pas à la direction du vent. Cela se produit sur certaines icônes, et de manière aléatoire. Ce ne sont pas toujours les mêmes qui posent problème.
On voit ici des icônes de vent d'Est, avec une description de vent SE. Le problème viendrait peut être du script de formatage des icônes ? Ou bien suis je le seul à avoir ce bug ?
Tant que nous sommes dans les icônes du vent, est il possible d'avoir, comme cela se passait avec conkyForecast, des icônes de différentes couleurs en fonction de la force du vent ? Car actuellement, ce n'est pas le cas, elles sont toujours vertes, y compris pour du vent de + de 50 km/h2/ Affichage du pourcentage de probabilité de pluie:
Comme cela est visible sur l'impression d'écran, j'ai un bug graphique avec un petit rectangle rouge pour tous les chiffres des pourcentage de pluie pour les soirées, ce qui correspond aux chiffres des lignes paires sur le fichier 'precipitation'. J'ai tout essayé pour tenter d'effacer ce bug, rien n'y fait. Si je demande d'afficher uniquement un chiffre d'une ligne paire, ce bug est toujours présent. Est il possible de régler ce problème ?3/ Améliorations possibles du script :
Etant donné que le code de la localité est défini dans le shell du script, je pense qu'il pourrait être intéressant d'extraire 2 données du fichier ICS : Le nom de la localité et ses coordonnées :
BEGIN:VEVENT
SEQUENCE:1
CLASS:PUBLIC
CREATED:20111028T000000Z
LAST-MODIFIED:20111028T000000Z
GEO:43.45000076;5.23000002
UID:1319803200-0-0
DTSTAMP:20111028T120000Z
DTSTART;VALUE=DATE:20111028
ORGANIZER;CN=Weather Underground:MAILTO:support@wunderground.com
DESCRIPTION:Friday - Partly Cloudy. High 21 C Wind SE 32 km/h. \nFriday Night - Chance of Rain. Low 15 C Wind East 32 km/h.Chance of precipitation 20%.
LOCATION:Marseille\, France
A savoir les lignes 'GEO' et 'LOCATION' (la mention du pays est superflue).
Ainsi, il est possible de les appeler et les faire afficher dans le conky.
Concernant les températures : Dans le fichier messages.wun les températures sont précédées des mentions 'Maxi' ou 'Mini'. Ces mentions peuvent toujours être rentrées 'à la main' dans le conky. Il me semble plus intéressant que de n'extraire que les données chiffrées brutes, et donc supprimer ces mention maxi ou mini du fichier messages.wun
Traductions dans le script : Rajouter 'Rain' 'Pluie' - Changer 'Clear' 'Ensoleillé' par 'Clear' 'Dégagé' car, la nuit, ensoleillé ne veut rien dire.4/ Evolution du script
Qu'il s'agisse du script wunderground ou celui de Météo France sur lequel travaillait Didier-T : Dans les 2 cas nous n'avons que l'affichage de prévisions, et en aucun cas l'affichage des données météo en live. Aussi, il me semble intéressant de rajouter ces données là (qui peuvent se substituer à la 1° partie du messages.wun, qui sont les prévisions de la journée.
Pour ce faire, j'ai trouvé un script python, qui permet d'aller chercher la T° et les conditions météo en cours chez Wunderground. Le voici :
#!/usr/bin/python
#
# Fetches Weather info from Weather Underground
#
# Usage: ./wundergound.py zipcode
#
# International:
# * Go to http://www.wunderground.com/
# * Find your city
# * Click the RSS icon
# * Station ID is the number that follows /stations/ in the url
#
#
# Values are either True or False
metric=True
international=True
import sys
import feedparser
def usage():
print("Usage:")
if international:
print(" ./wunderground.py StationID")
else:
print(" ./weunderground.py zipcode")
sys.exit(1)
if not len(sys.argv) == 2:
usage()
location=sys.argv[1]
if international:
url="http://rss.wunderground.com/auto/rss_full/global/stations/"
else:
url="http://rss.wunderground.com/auto/rss_full/"
feed=feedparser.parse(url+location)
if not feed.feed:
# Assume Error
print("Error")
sys.exit(1)
current=feed['items'][0].title
if metric:
temp=current.split(",")[0].split(":")[1].split("/")[1].strip()
else:
temp=current.split(",")[0].split(":")[1].split("/")[0].strip()
condition=current.split(",")[1].split("-")[0].strip()
print(temp, "-", condition)
Je pense qu'il est également possible par le même biais d'aller chercher les données relatives au vent...
Les problèmes à régler avec ce script sont les suivants :
Comment faire afficher ces données dans le conky ?
Une ligne telle que celle ci dans le conky
${execi 600 /home/chemin du conky/wunderground 'zip code'}
fait apparaître une ligne d'affichage avec Température - condition météo. C'est pas terrible.
Comment faire associer les conditions météo avec l'icône du temps qui y est associée ?
Je laisse ces questions à toute la connaissance dans l'écriture des scripts des spécialistes
Je suis prêt à tester toutes les propositions qui seront faites !

Bonjour Phyllinux,
Pour ton soucis n°2 tu peut tenter de changer de police de caractère, sa devrais régler le problème.
pour le reste il faudrait que tu compresse ton répertoire de travail pour le mettre en ligne, et que tu nous fournisses ton conkyrc.
Bien sure je prend bonne note de tes remarques pour la suite.
Je savais pas que les icônes de vent changeaient de couleur en fonction de la vitesse (pourrais tu m'indiquer les paliers).

Re : [Conky] Alternative à weather.com ( icones conkyforecast )
J'ai essayé de changer la police, mais pas d'évolution . J'ai toujours le même bug, quelle que soit la police utilisée.
Concernant les couleurs en fonction des vitesses du vent, je ne sais pas quels sont les paliers définis dans conkyforecast, et je n'ai pas réussi à trouver dans quel fichier cela était défini.
Je pense cependant que l'on peut partir sur la base suivante :
De 0 à 25 : Vert
De 26 à 50 : Orange
> 50 km/h : Rouge
Pour le répertoire de travail, je fais un fichier et je le poste tout à l'heure

Non, j'ai fait la modif, et cela ne règle rien du tout.

gilles@ubuntu:~$ conky -c /home/gilles/conky/meteo/conkyrc1
Conky: forked to background, pid is 27310

cp: la cible «/home/gilles/conky/meteo/images/conky/v2.png» n'est pas un répertoire

en
cp "${DirShell}/images/vent/$fichier.png" ${DirShell}/images/conky/v$n.png

Re : [Conky] Alternative à weather.com ( icones conkyforecast )
Sinon, il y a une autre alternative.
Au lieu de Weather Underground, Météo France, Weather.com, il existe aussi ACCUWEATHER.
Et avec le dernier script de TeoBigusGeekus, on peut arriver à cela :
Au passage, on voit que c'est un début de semaine pourri sur La Canebière!
Pour la marche à suivre, voir ici :
conky Accuweather post #2
Si quelqu'un sait retravailler le script pour pouvoir traduire les 'Conditions Météo' (Pluie, Soleil, Couvert...), ainsi que les jours, je suis preneur, ainsi que TeoBigusGeekus d'ailleurs
Je recherche également comment extraire les icônes, les conditions météo et les températures pour pouvoir les insérer dans un autre conky (l'horloge avec la météo intégrée qui tourne actuellement sous conkyforecast).
Je sais qu'il est toujours possible de faire afficher les points qui m'intéressent en faisant tourner le script et en allant les chercher. Mais c'est aussi simple si ils sont dans un fichier généré (à l'image du fichier messages.wun).
Merci pour vos propositions

En s'actualisant, la traduction s'est faite : PARTLY SUNNY est devenu Partiellement Ensoleillé (Même la casse s'est modifiée : De tout majuscule, on est passé à 1° lettre en majuscule, le reste en minuscule).
Il ne me reste donc plus qu'à voir comment extraire les données qui m'intéressent pour les basculer également sur mon autre conky :

Re : [Conky] Alternative à weather.com ( icones conkyforecast )
Bonjour
En passant à ocelot, je me suis dit que j'allais améliorer mon conky jusque là assez sommaire.
Je suis assez déçu de voir se mélanger les posts pour les différents services de meteo ( méteofrance, accuweather wunderground ... ) Pour tout dire, et sans vouloir vous vexer car vous faite bien avancer les choses, c'est vraiment le boxon dans ce thread . Je ne sais pas si c'est possible d'améliorer les choses en regroupant les infos pour chaque fournisseur dans un seul message; enfin passons.
Pour en revenir à conky
Je tente d'installer le conky de Didier T post 21 et j'ai qqs problèmes
-Il semble manquer des icones (celles du repertoire /conky ( les autres étant dispatchées dans différant messages... pas tres pratique )
- il ne semble pas trouver les infos sur le site, pour calais le code est bien 621930 ??
-j'ai ce message d'erreur :
sed: impossible de lire /home/olivier/.conky//tt: Aucun fichier ou dossier de ce type
Conky: Unable to load image '/home/olivier/.conky/conky/j1.gif'
ps j'ai modifié le répertoire test en .conky
voilà. Bon dimanche Olivier

Rebonjour
Juste pour rajouter un site qui permet aussi d'avoir les prévisions météorologiques ( les prédictions météorologiques étant un terme réservées à meteo france AMHA) . Il s'agit de www.windguru.cz
Il est très utilisé pour les sports nautiques ( voile, kitesurf...). Un utilisateur a déjà tenté de faire qq chose : voir ici

@ olitask,
bonjour pour commencer le conky météo france est une impasse car le nombre d'infos change au fur et à mesure que la journée avance, mais voici certainement les raisons de tes soucis :
Il doit manquer le chemin "/home/olivier/.conky/conky/" qui sert à charger les icônes météo France
le chemin indiqué dans ton DirShell est "$HOME/.conky/" supprime le dernier "/" sa ira mieux
Oui 621930 correspond bien à ta ville

Re : [Conky] Alternative à weather.com ( icones conkyforecast )
@ Olitask
Il est normal que tu trouves ce topic un peu 'brouillon'. En effet, nous cherchons une alternative à conkyForecast, étant donné que les données utilisées par conkyForecast proviennent du site Weather.com, et que l'accès à ces données sera fermé dans très peu de temps.
Du coup, nous tâtonnons afin de trouver une solution qui nous convienne.
Nous sommes partis sur les possibilités offertes par Weather Underground (alias Wunderground).
De là Didier-T a essayé de récupérer les données provenant du site de Météo France, à l'instar de ce qui était fait par le script téléchargeant les données sur Wunderground.
De mon côté, tout en continuant à tester les différents scripts, j'ai trouvé une possibilité avec un autre site météo : Celui d'Accuweather.
Ce topic est un donc en quelque sorte un 'laboratoire' où tout le monde apporte ses idées et fait part de ce qu'il a pu trouver.
Il s'avère qu'actuellement, le conky le plus abouti est celui utilisant le script récupérant les données d'Accuweather. Tu trouveras le lien sur mon post #38.
Didier-T a modifié le script afin d'avoir la totalité des données en français (post #40) au lieu de la version originale en langue anglaise.
Donc, si tu veux un conky météo fonctionnel et en français, tu peux partir sur ces bases.
De mon côté, je tourne avec celui là, sur lequel je rajoute une couche du script réalisé par Didier-T et Levi59 afin d'obtenir en complément le pourcentage de probabilité de pluie (script avec les données de wunderground), étant donné que Accuweather ne fournit pas ces pourcentages dans les fichiers générés par le script.
Bon conky

Merci de votre réponse. En fait, il a suffit de créer le répertoire conky a coté de /vent et /metéo.
Petit problème , le résultat me donne cela : les icônes sont décalées

quel est le paramètre qu'il faut modifier ?
Je vais me pencher sur accuweather, mais il faut s'enregistrer sur le forum ubuntu anglais ...

Re : [Conky] Alternative à weather.com ( icones conkyforecast )
@ Didier-T et Levi59
Je suis satisfait du résultat obtenu avec les script d'Accuweather. Merci Teo pour son script d'origine et merci Didier-T pour la modification avec la traduction
J'ai réussi à intégrer les données extraites dans mon autre conky qui donne des infos simplifiées pour la météo. (Je lance mes différents conkys par des scripts Nautilus pour afficher ce que je veux quand je le désire, avec un simple clic droit de souris).
Sur ce dernier, j'ai ajouté la couche du script wunderground (merci Didier-T et Levi59 pour leur travail ) pour avoir les pourcentages de probabilité de précipitations.
Maintenant, pour être pleinement satisfait du résultat obtenu, il ne me manque plus qu'à régler le problème du bug graphique que j'ai déjà présenté (le petit carré qui se rajoute après le chiffre).
Ce bug ne touche que les lignes paires du fichier 'precipitation' généré par le script wunderground.
J'ai essayé en changeant la police, en changeant l'ordre d'affichage, rien à faire. Dès que je demande d'afficher un pourcentage pour la nuit, j'ai ce petit carré.
L'un d'entre vous pourrait il trouver la raison de ce bug ?
Si j'arrive à le supprimer, je serais satisfait à 100% du résultat final !
A titre info, si l'un d'entre vous est intéressé, voici ce que cela donne (avec juste l'affichage des pourcentages de probabilités de pluie dans la journée pour la raison évoquée ci dessus). Je pourrais vous poster les différents fichiers nécessaires.
@ Olitask
Essaye en mettant {voffset -X} en début de la ligne qui te fait afficher les icônes du vent.
Par essais multiples en changeant la valeur du X de ton voffset, tu devrais réussir à trouver le bon positionnement
voffset (pixels) Change vertical offset by N pixels. Negative values will cause text to overlap. See also $offset.

en générale ta ligne d'affichage se présente ainsi

donc x représente l'axe gauche droite (le plus à gauche étant 0)

I have a simple question in python. If I have a Facebook page ID let say '6127898346' for example, how can I retrieve this page information such as (Likes count) , and store the result on a file?
Use some sort of Facebook API package, like https://github.com/pythonforfacebook/facebook-sdk available with
import facebook
graph = facebook.GraphAPI()
page = graph.get_object('6127898346')
print '{} has {} likes.'.format(page['name'], page['likes'])
Easy way to save everything:
import json
with open('outf.json', 'w') as f:
json.dump(page, f)

You are provided with a function Rand5(). This function returns perfectly random (equal distribution) integers between 1 and 5.
Provide the function Rand7(), which uses Rand5() to produce perfectly random integers between 1 and 7.
Java - 61 chars
int rand7(){int s=0,c=7;while(c-->0)s+=rand5();return s%7+1;}
Test driver for validation:
class Rand {
public static void main(String[] args) {
int[] nums = new int[7];
// get a lot of numbers
for(int i = 0; i < 10000000; i++) nums[rand7()-1]++;
// print the results
for(int i = 0; i < 7; i++) System.out.println((i+1) + ": " + nums[i]);
}
// just for rand5()
static java.util.Random r = new java.util.Random();
static int rand5() {
return r.nextInt(5)+1; // Random.nextInt(n) returns 0..n-1, so add 1
}
static int rand7(){int s=0,c=7;while(c-->0)s+=rand5();return s%7+1;}
}

JavaScript,
Perl - 47 (was 52) chars
sub rand7{($x=5*&rand5+&rand5-3)<24?int($x/3):&rand7}
Plus I get to use the ternary operator AND recursion. Best... day... ever!
OK, 47 chars if you use mod instead of div:
sub rand7{($x=5*&rand5+&rand5)<30?$x%7+1:&rand7}
Ruby - 54 chars (based on Dan McGrath solution, using loop)
def rand7;x=8;while x>7 do x=rand5+5*rand5-5 end;x;end
Ruby - 45 chars (same solution, using recursion)
def rand7;x=rand5+5*rand5-5;x>7 ?rand7: x;end
In Python:
def Rand7():
while True:
x = (Rand5() - 1) * 5 + (Rand5() - 1)
if x < 21: return x/3 + 1
In Common Lisp 70 characters:
(defun rand7()(let((n(-(+(rand5)(* 5(rand5)))5)))(if(> n 7)(rand7)n)))
The parenthesis take up more space than I would like.
In c/c++ using rejection sampling
int rand7(){int x=8;while(x>7)x=rand5()+5*rand5()-5;return x;}
62 characters.
Translation to PHP, from the answer posted ny Dan McGrath.
function Rand7(){$x=8;while($x>7)$x=rand5()+5*rand5()-5;return $x;}

int Rand7(){int n=0;for(int i=0;i<3;++i){int r=Rand5();while(r==5) r=Rand5();--r;r&=1;n|=r<<i;} return n;}
(Going for speed.)
R, 34 characters
In R (a language built for statistical computation), a deliberately cheaterish solution:
# Construct a Rand5 function
Rand5 <- function() sample(seq(5),1)
# And the golf
Rand7=function(r=Rand5())sample(1:(r/r+6),1)
# Or (same character count)
Rand7=function(r=Rand5())sample.int(r/r+6,1)
# Or even shorter(thanks to @Spacedman)
Rand7=function()sample(7)[Rand5()]
Thanks to lazy evaluation of arguments, I eliminated the semicolon and braces.

I know there's shorter answer, but I wanted to show the test of this puzzle. It turns out that only Clyde Lobo's answer using Dan McGrath's rejection sampling is correct (between JS answers).
С++
int Rand7()
{
int r = Rand5();
int n = 5;
do {
r = (r - 1) * 5 + Rand5();
int m = n * 5 / 7 * 7;
if (r <= m) {
return r % 7 + 1;
}
r -= m;
n = n * 5 - m;
} while (1);
}
Numbers distribution (1000000 integers):
Average number of calls to Rand5() per every generated integer is about 2.2 (2 to 10+).
Python, 70 chars
def rand7():
while True:
n=5*(rand5()-1)+(rand5()-1)
if n<21:return n%7+1
but completely correct based on the reasoning here.
Java, 65 chars:
int rand7(){int r;do{r=rand5()+5*rand5()-5;}while(r>7);return r;}
int result = 0;
for (int i = 0; i++; i<7)
if (((rand(5) + rand(5)) % 2) //check if odd
result += 1;
return result + 1;
R (30 characters)
Define rand7:
rand7=function(n)sample(7,n,T)
Because R was written with statistical analysis in mind, this task is trivial, and I use the built-in function
Sample output:
> rand7(20)
[1] 4 3 6 1 2 4 3 2 3 2 5 1 4 6 4 2 4 6 6 1
> rand7(20)

> rand7(20)
[1] 6 7 1 3 3 1 5 4 3 4 2 1 5 4 4 4 7 7 1 5
Perl, 43 chars, iterative rejection sampling
sub rand7{1while($_=5*&rand5-rand5)>6;$_+1}
This gives a warning about
Ps. The following 46-char version is about three times faster:
sub rand7{1while($_=5*&rand5-rand5)>20;$_%7+1}
Groovy
rand7={if(b==null)b=rand5();(b=(rand5()+b)%7+1)}
example distribution over 35,000 iterations:
Is it bad that it's stateful?

Rand7=Rand5[]~Sum~{7}~Mod~7+1&
Java - 66 chars
int rand7(){int s;while((s=rand5()*5+rand5())<10);return(s%7+1);}
Longer than previous routine, but I think this one returns uniformly distributed numbers in less time.
This uses binary token encoding, therefore, here is a hexdump:

To try it out, you can also download it.
Here is the ungolfed and commented code, together with testing code.
% This is the actual rand7 procedure.
/rand7{
8{ % potentialResult
% only if the random number is less than or equal to 7, we're done
dup 7 le{ % result
exit % result
}if % potentialResult
pop % -/-
2{rand5}repeat % randomNumber1 randomNumber2
5 mul add 5 sub % randomNumber1 + 5*randomNumber2 - 5 = potentialResult
}loop
}def
%Now, some testing code.
% For testing, we use the built-in rand operator;
% Doesn't really give a 100% even distribution as it returns numbers
% from 0 to 2^31-1, which is of course not divisible by 5.
/rand5 {
rand 5 mod 1 add
}def
% For testing, we initialize a dict that counts the number of times any number
% has been returned. Of course, we start the count at 0 for every number.
<<1 1 7{0}for>>begin
% Now we're calling the function quite a number of times
% and increment the counters accordingly.
1000000 {
rand7 dup load 1 add def
}repeat
% Print the results

Distribution test:
Algorithm:
> The numbers are not mutually uncorrelated anymore, but individually perfectly random.
How about this?
int Rand7()
{
return Rand5()+ Rand5()/2;
}
static unsigned int gi = 0;
int rand7()
{
return (((rand() % 5 + 1) + (gi++ % 7)) % 7) + 1;
}
//call this seed before rand7
//maybe it's not best seed, if yo have any good idea tell me please
//and thanks JiminP again, he remind me to do this
void srand7()
{
int i, n = time(0);
for (i = 0; i < n % 7; i++)
rand7();
}
The srand7() is the seed of rand7, must call this function before rand7, just like call srand before rand in C.
This is a very good one, because it call rand() only one time, and no loop thing, no expends extra memories.
Let me explain it: consider a integer array with size of 5:
So we got the TABLE, each one of 1-7 appears 5 times in it, and has all 35 numbers, so the probability of each number is 5/35=1/7. And next time,
After enough times, we can get the uniform distribution of 1-7.
So, we can allocate a array to restore the five elements of 1-7 by loop-left-shift, and get one number from array each time by rand5. Instead, we can generate the all seven arrays before, and using them circularly. The code is simple also, has many short codes can do this.
But, we can using the properties of % operation, so the table 1-7 rows is equivalent with (rand5 + i) % 7, that is : a = rand() % 5 + 1 is rand5 in C language, b = gi++ % 7 generates all permutations in table above, and 0 - 6 replace 1 - 7 c = (a + b) % 7 + 1, generates 1 - 7 uniformly. Finally, we got this code:
(((rand() % 5 + 1) + (gi++ % 7)) % 7) + 1
But, we can not get 6 and 7 at first call, so we need a seed, some like srand for rand in C/C++, to disarrange the permutation for first formal call.
Here is the full code to testing:
#include <stdio.h>
#include <stdlib.h>
#include <time.h>
static unsigned int gi = 0;
//a = rand() % 5 + 1 is rand5 in C language,
//b = gi++ % 7 generates all permutations,
//c = (a + b) % 7 + 1, generates 1 - 7 uniformly.
//Dont forget call srand7 before rand7

This took about 20 hours of CPU time to find, and about 2 minutes per prime to prove. In contrast, the 84 digit solution can be found in around 3 minutes.

I recommend this tool if you want to confirm primality: D. Alpern's ECM Applet
Also using a repdigit approach, which seems to be the approach most likely to find large values. The following script algorithmically skips over most numbers or truncations which will result in multiples of 2, 3, 5 and now 11 c/o PeterTaylor (his contribution increased the efficiency by approximately 50%).

Alternatively, you could also use the gmpy.is_prime function: GMPY Project
Some small speed improvements as a result of profiling. The primality check for the longest of the four candidates has been moved to the end, xrange replaces range, and long replaces int type casts. int seems to have unnecessary overhead if the evaluated expression results in a long.
Divisibility Rules
Let N be a postitive integer of the form a...ab...bc...c, where a, b and c are repeated digits.
By 2 and 5
- To avoid divisibility by 2 and 5, c may not be in the set [0, 2, 4, 5, 6, 8]. Additionally, if b is a member of this set, the length of c may be no less than 2.
By 3
- If N = 1 (mod 3), then N may not contain any of [1, 4, 7], as removing any of these would trivially result in a multiple of 3. Likewise for N = 2 (mod 3) and [2, 5, 8]. This implementation uses a slightly weakened form of this: if N contains one of [1, 4, 7], it may not contain any of [2, 5, 8], and vice versa. Additionally, N may not consist solely of [0, 3, 6, 9]. This is largely an equivalent statement, but it does allow for some trivial cases, for example a, b, and c each being repeated a multiple of 3 times.
By 11
- As PeterTaylor notes, if N is of the form aabbcc...xxyyzz, that is it consists only of digits repeated an even number of times, it is trivially divisible by 11: a0b0c...x0y0z. This observation eliminates half of the search space. If N is of odd length, then the length of a, b and c must all be odd as well (75% search space reduction), and if N is of even length, then only one of a, b or c may be even in length (25% search space reduction).
- Conjecture: if abc is a multiple of 11, for example 407, then all odd repetitions of a, b and c will also be multiples of 11. This falls out of the scope of the above divisibility by 11 rule; in fact, only odd repetitions are among those which are explicitly allowed. I don't have a proof for this, but systematic testing was unable to find a counter-example. Compare: 444077777, 44444000777, 44444440000077777777777, etc. Anyone may feel free to prove or disprove this conjecture. aditsu has since demonstrated this to be correct.
Other Forms
2 sets of repeated digits
Numbers of the form that randomra was pursuing, a...ab...b, seem to be much more rare. There are only 7 solutions less than 101700, the largest of which is 12 digits in length.
4 sets of repeated digits
Numbers of this form, a...ab...bc...cd...d, appear to be more densely distributed than those I was searching for. There are 69 solutions less than 10100, compared to the 32 using 3 sets of repeated digits. Those between 1011 and 10100 are as follows:

There's a simple heuristic argument as to why this should be the case. For each digital length, there is a number of repeated sets (i.e. 3 repeated sets, or 4 repeated sets, etc.) for which the expected number of solutions will be the highest. The transition occurs when the number of additional possible solutions, taken as a ratio, outweighs the probability that the additional number to be checked is prime. Given the exponential nature of the possibilities to check, and the logarithmic nature of prime number distribution, this happens relatively quickly.
If, for example, we wanted to find a 300 digit solution, checking 4 sets of repeated digits would be far more likely to produce a solution than 3 sets, and 5 sets would be more likely still. However, with the computing power that I have at my disposal, finding a solution much larger than 100 digits with 4 sets would be outside of my capacity, let alone 5 or 6. |
I am using a set operation in python to perform a symmetric difference between two numpy arrays. The result, however, is a set and I need to convert it back to a numpy array to move forward. Is there a way to do this? Here's what I tried:
a = numpy.array([1,2,3,4,5,6])
b = numpy.array([2,3,5])
c = set(a) ^ set(b)
The results is a set:
In [27]: c
Out[27]: set([1, 4, 6])
If I convert to a numpy array, it places the entire set in the first array element.
In [28]: numpy.array(c)
Out[28]: array(set([1, 4, 6]), dtype=object)
What I need, however, would be this:
array([1,4,6],dtype=int)
I could loop over the elements to convert one by one, but I will have 100,000 elements and hoped for a built-in function to save the loop. Thanks! |
