I installed Anaconda a while ago but recently decided to uninstall it and just install basic python 2.7. I removed Anaconda and deleted all the directories and installed python 2.7. But when I go to install PyGTK for Windows it says it will install it to the c:/users/.../Anaconda directory - this doesn't even exist. I want to install it to the c:/python-2.7 directory. Why does it think Anaconda is still installed? And how can I change this?

In my computer there wasn't a uninstaller in the Start Menu as well. But it worked it the Control Panel > Programs > Uninstall a Program, and selecting Python(Anaconda64bits) in the menu. (Note that I'm using Win10)

In the folder where you installed Anaconda (Example: C:\Users\username\Anaconda3) there should be an executable called Uninstall-Anaconda.exe. Double click on this file to start uninstall Anaconda. That should do the trick as well.

Method1: To uninstall Anaconda3 go to the Anaconda3 folder, there u will be able to find an executable called Uninstall-Anaconda3.exe, double click on it. This should uninstall ur application. There are times when the shortcut of anaconda command prompt,jupyter notebook, spyder, etc exists, so delete those files too. Method2 (Windows8): Go to control panel->Programs->Uninstall a Program and then select Anaconda3(Python3.1. 64-bit)in the menu.

Pip is not in C:\Python27. It's in C:\Python27\Scripts. Check that folder to make sure there is a pip.exe, if there is then it should have installed fine, and make sure that C:\Python27\Scripts is in your PATH.

python

Assumptions: You're running on Windows and installed the basic python for windows (which includes idle) and probably stuck with the defaults (so you should have python in c:\python35) Related assumptions: Windows doesn't have an out of the box loopback interface and trying to enable one is going to be more painful than working around it. Recommendations: You might want to try to sneakernet (i.e. download on a friend's computer to a USB stick and then copy over) pycharm or another IDE, but I don't know if they won't have the same problem If that doesn't work, you should be able to (as an interim step while you wait for a new computer): Use Idle (with the -n flag) to edit your python program(s) [because trying to edit python programs in Wordpad is cruel], save your program as myprogram.py Open up cmd (dos prompt), cd to your save directory, do c:\python35\python.exe myprogram.py Repeat 1+2 as needed

I need some help. Im trying to run Python IDLE on my computer but I get the following error: IDLE can't bind to a TCP/IP port, which is necessary to communicate with its Python execution server. This might be because no networking is installed on this computer. Run IDLE with the -n command line switch to start without a subprocess and refer Help/IDLE Help 'Running without a subprocess' for further details. My networking card just fried a couple days ago so I think this might be the problem, I dont know. I also tried refer to IDLE Help but I couldn't understand a thing. Is there anyway I can get by this problem. I need this program operational for my programming class' a least until my new computer arrives.

By using -n flag, you can use it for one time only. It means closing python idle, I'll have to redo -n flag process whenever I want to open .

I want to write a simple program to manage the screen brightness on my laptop, running Python3 under Ubuntu Linux. To directly change the screen brightness levels, I can deal with a single file in the folder /sys/class/backlight/acpi_video0, called brightness. (the maximum brightness is another text file called max_brightness, so it's easy to find) The problem is, however, that I want to grant my program partial access to root permissions, just enough to modify the files in that folder (though, I'd like it to be flexible enough to choose any folder in /sys/class/backlight/, in case it's not named acpi_video0), but not actually run as root, as that may cause problems as it tries to access GTK for a graphical interface. How do I grant a Python3 program partial root permissions?

It is basically useless if you don't have executable permission in the remote machine. You need to contact your administrator to obtain an executable permission. In the case for the SCP files to the remote server, you may still be able to cp you files but you may not be able to execute it.

I have an issue that I can't seem to find a solution within python. From command line I can do this by: sed '1,/COMMANDS/d' /var/tmp/newFile This delete everything from line #1 till regex "COMMANDS". Simple But I can't do the same with Python that I can find. The re.sub and multiline doesn't seem to work. So I have a question how can I do this in a pythonic way? I really rather not run sed from within python unless I have to.

If all your program does is print something and you run it by double-clicking the executable, then it simply closes the console when it finishes running. If you want the window to stay open, run your program from the command line. You can also create a batch file that runs your program and then pauses the console, so that you at least get a "press any key" before the console closes.

This question doesn't really make sense. Presumably LINQ, like any .NET library, can be used in any language that runs in the CLR: C#, VB, IronPython, IronRuby, etc. The most common cross-language runtime that works on Linux is the Java VM, and you can use Java libraries - including ORMs like JDO - in any language that uses that VM: Java, Scala, Clojure, Jython, JRuby, etc.

The predominant ORMs that run in a linux-based environment seem to be written around a specific language. Microsoft LINQ, however, supports access from a number of languages. Can I do this in linux-land (i.e. non-LINQ-land, non-JVM-land), for example between native versions of Python and Ruby?

It seems that the only way to do this is to use languages which share a common VM, such as .NET CLR (and LINQ) or the Java JVM (Hibernate, Eclipse Link, etc). So for the various languages running in their native implementation, the answer is no.

I am about to go down a road I really don't want to go on.... That entire CPU row is rather nice, since it totals to 100 and it is easy to log and plot. Thanks in advance.

Which will give the best performance Hive or Pig or Python Mapreduce with text file and oracle table as source?

29,991,069

python,hadoop,mapreduce,hive,apache-pig

Python Map Reduce or anything using Hadoop Streaming interface will most likely be slower. That is due to the overhead of passing data through stdin and stdout and the implementation of the streaming API consumer (in your case python). Python UDF's in Hive and Pig do the same thing. You might not want to compress data flow into ORC on the Python side. You'll be subjected to using Python's ORC libraries, which I am not sure if they are available. It would be easier if you let Python return your serialized object and the Hadoop reduce steps to compress and store as ORC (Python as a UDF for computation) Yes. Pig and Python have some what of a nice programmatic interface where in you can write python scripts to dynamically generate Pig Logic and submit it in parallel. look up Embedding Pig Latin in Python. It's robust enough to define Python UDFS and let Pig do the overall abstraction and job optimization. Pig does a lazy evaluation so in cases of multiple joins or multiple transformations it can demonstrate pretty good performance in the optimizing the complete pipe line. You say HDP 2.1. Have you had a look at Spark ? If performance is important to you and looking at the datasets size which dont look huge you ll expect many time faster overall pipeline execution than Hadoop s native MR engine

I have the below requirements and confused about which one to choose for high performance. I am not java developer. I am comfort with Hive, Pig and Python. I am using HDP2.1 with tez engine. Data sources are text files(80 GB) and Oracle table(15GB). Both are structured data. I heard Hive will suite for structure data and Python map reduce streaming concept too will have high performance than hive & Pig. Please clarify. I am using Hive and the reasons are: need to join those two sources based on one column. using ORC format table to store the join results since the data size is huge text file name will be used to generate one output column and that has been performed with virtual column concept input__file__name field. After join need to do some arithmetic operations on each row and doing that via python UDF Now the complete execution time from data copy into HDFS to final result taken 2.30 hrs with 4 node cluster using Hive and Python UDF. My questions are: 1) I heard Java Mapreduce always faster. Will that be true with Python Map reduce streaming concept too? 2) Can I achieve all the above functions in Python like join, retrieval of text file name, compressed data flow like ORC since the volume is high? 3) Will Pig join would be better than Hive? If yes can we get input text file name in Pig to generate output column? Thanks in advance.

Can anyone tell me what is the problem and how to solve it? This is amazing!! Even in StackOverFlow no one could give me any solution!!

Is it possible to run java command line app from python in AWS EC2?

Since you're just making a command line call to the Java app, the path of least resistance would just be to make that call from another server using ssh. You can easily adapt the command you've been using with subprocess.call to use ssh -- more or less, subprocess.call(['ssh', '{user}@{server}', command]) (although have fun figuring out the quotation marks). As an aside on those lines, I usually find using '-o StrictHostKeyChecking=no -o UserKnownHostsFile=/dev/null' stabilizes scripted SSH calls in my environment. The more involved thing will be setting up the environments to properly run the components you need. You'll need to set up ssh configs so that your django app can ssh over and set up -- probably with private key verification. Then, you'll need to make sure that your EC2 security groups are set up to allow the ssh access to your java server on port 22, where sshd listens by default. None of this is that hairy, but all the same, it might be stabler to just wrap your Java service in a HTTP server that your Django app can hit. Anyway, hope this is helpful.

I'd like to know how to make an executable Python file on OS X, that is, how to go about making an .exe file that can launch a Python script with a double click (not from the shell). For that matter I'd assume the solution for this would be similar between different scripting languages, is this the case?

I have found that making the 'python' alias replace the default version of python that the system comes with is a bad idea. When you install a new version of python (3.4 for instance), these two new commands are installed, specifically for the version you installed: pip3.4 python3.4 If you're using an IDE that wants you to indicate which python version you are using the IDE will let you navigate to it in the Library folder pip will still be for python2.7 after you download some other python version, as I think that's the current version osx comes installed with

Try python3 or python3.4. It should print out the right version if correctly installed. Python 3.4 already has pip with it. You can use python3 -m pip to access pip. Or python3 -m ensurepip to make sure that it's correctly installed.

I understand that to communicate with RabbitMQ, you would require any lib that abides by AMQP specification. Kombu is one such lib which can bind to the RabbitMQ exchange, listen and process messages by spawning numerous consumers. Celery is nothing but an asynchronous task generator which has numerous add-ons like in-memory processing, capacity to write to DB/Redis cache, perform complex operations and so on. Said that now you can use kombu to read and write messages in/from RMQ and use celery workers to process the message.

how to execute shell script in the same process in python

python,shell

What if you make a 'master' shell script that would execute all the others in sequence? This way you'll only have to create a single sub-process yourself, and the individual scripts will share the same environment. If, however, you would like to interleave script executions with Python code, then you would probably have to make each of the scripts echo its environment to stdout before exiting, parse that, and then pass it into the next script (subprocess.Popen() accepts the env parameter, which is a map.)

No, you cannot run more than one program (bash, python) in the same process at the same time. But you can run them in sequence using exec in bash or one of the exec commands in python, like os.execve. Several things survive the "exec boundary", one of which is the environment block. So in each bash script you exec the next, and finally exec your python. You might also consider using an IPC mechanism like a named pipe to pass data between processes. I respectfully suggest that you look at your design again. Why are you mixing bash and python? Is it just to reuse code? Even if you managed this you will end with a real mess. It is generally easier to stick with one language.

With some editors you can define the 'execute' command, For example with Geany, for Python files, F5 is python2.7 %f. That could be modified to something like python2.7 %f dummy parameters. But I use an attached terminal window and its line history more than F5 like commands. I'm an Ipython user, so don't remember much about the IDLE configuration. In Ipython I usually use the %run magic, which is more like invoking the script from a shell than from an IDE. Ipython also has a better previous line history than the shell. For larger scripts I like to put the guts of the code (classes, functions) in one file, and test code in the if __name__ block. The user interface is in another file that imports this core module.

So I'm writing Python with IDLE and my usual workflow is to have two windows (an editor and a console), and run my script with F5 to quickly test it. My script has some non-optional command line parameters, and I have two conflicting desires: If someone launches my script without passing any parameters, I'd like him to get an error telling him to do so (argparse does this well) When I hit F5 in IDLE, I'd like to have my script run with dummy parameters (and I don't want to have more keystrokes than F5 to have this work, and I don't want to have a piece of code I have to remember to remove when I'm not debugging any more) So far my solution has been that if I get no parameters, I look for a params.debug file (that's not under source control), and if so, take that as default params, but it's a bit ugly... so would there be a cleaner, more "standard" solution to this? Do other IDEs offer easier ways of doing this? Other solutions I can think of: environment variables, having a separate "launcher" script that's the one taking the "official" parameters. (I'm likely to try out another IDE anyway)

I am working on a Python/MySQL cloud app with a fairly complex architecture. Operating this system (currently) generates temporary files (plain text, YAML) and log files and I had intended to store them on the filesystem. However, our prospective cloud operator only provides a temporary, non-persistent filesystem to apps. This means that the initial approach with storing the temporary and log files won't work. There must be a standard approach to solving this problem which I am not aware of. I don't want to use object storage like S3 because it would extend the current stack and add complexity. But I have the possibility to install an additional, dedicated app (if there is anything made for this purpose) on a different server with the same provider. The only limitation is that it would have to be in PHP, Python, MySQL. The generic question: What is the standard approach to storing files when no persistent filesystem is available? And for my specific case: Is there any solution using Python and/or MySQL which is simple and quick to implement? Is this a usecase for Redis?

Questions on Twisted Protocols and loopingCall

29,664,919

python,twisted

Things get garbage collected when there are no more references to them, so I can't say when objects in your program will be collected. However, I can tell you about the references kept from Twisted. A Protocol connected to a Transport will have a reference that goes globals→reactor→transport→protocol. When the transport is closed, the reference from the reactor to the transport is broken. The reactor only references the transport to deliver events to it, and since a disconnected transport has no events to deliver, the reactor can drop it. The protocol therefore no longer is referenced by the reactor. At that point, if no other globals or active stack variables reference it, it will be collected. A LoopingCall is referenced by globals→reactor→DelayedCall (the object returned by callLater)→LoopingCall.__call__ bound method→LoopingCall. If the LoopingCall's f attribute (the callable it's calling) still references your Protocol, then yes, your Protocol object will continue to live in memory. But, since it no longer has a useful transport, there's not that much you can do with it.

Suppose I have a python twisted app with the standard Factory and Protocol subclasses. My Protocol subclass connectionMade() method launches a loopingCall that runs (say) every 5 minutes. I have two questions: Suppose the connection gets lost. Yes I know that this will result in the connectionLost() method being called. But what happens the protocol object itself? When does that stop existing? Does it get garbage collected right away? What happens to the loopingCall in that protocol? If I don't explicitly cancel it, does that mean it keeps running forever and prevents the protocol from getting garbage collected?

Ok, I figured this one out by myself. The problem the python process runs into is that the HDFS uses symlinks. Python on the other hand does not accept symlinks as valid files so will not import from them if in the same directory. Instead of adding each file to the Distributed Cache, you can add the directory to the cache, then any calls to the directory are via the symlink but calls to files are then in the actual directory, allowing the python process to import libraries

Ok, I am writing a java based Hadoop MR task. Part of the task is calling an outside python script as a new Process, passing it information and reading it back the resut. I have done this a few times before without problems when not working with hadoop. I can also call a single python script as a new process in hadoop when it does not import anything, or only things that are on the nodes' python install. the current python script calls an import on another script which is usually just sitting in the same directory and that works fine when not running on hadoop. In hadoop I have added both files to the distributed cache so I do not understand why the script could not import the other one.

You can have as many as you like and put them where it's convenient. A common arrangement is to have a dedicated environment for each project; then if each project is in ~/projects/<project> you could have a virtualenv directory in each project's respective root directory. So ~/projects/foo/.env for the virtualenv for project foo, ~/projects/bar/.env for the one for bar, etc. (The use of .env is just a convention; again, you can name them any way you like.)

You might be looking for the readlink command. You can use readlink -m "some/path" to convert a path to the canonical path format. It's not quite path.join but it does provide similar functionality. Edit: As someone pointed out to me readlink is actually more like os.path.realpath. It is also a GNU extension and not available on all *nix systems. I will leave my answer here in case it still helps in some way.

python,multithreading,tcpclient

Calling for a best way or code examples is rather off topic, but this is too long to be a comment. There are three general ways to build those terminal emulator like applications : multiple processes - the way the good old Unix cu worked with a fork multiple threads - a variant from the above using light way threads instad of processes using select system call with multiplexed io. Generally, the 2 first methods are considered more straightforward to code with one thread (or process) processing upward communication while the other processes the downward one. And the third while being trickier to code is generally considered as more efficient As Python supports multithreading, multiprocessing and select call, you can choose any method, with a slight preference for multithreading over multiprocessing because threads are lighter than processes and I cannot see a reason to use processes. Following in just my opinion Unless if you are writing a model for rewriting it later in a lower level language, I assume that performance is not the key issue, and my advice would be to use threads here.

I've done some work with WMI before (though not from Python) and I would not try to use it for a project like this. As you said WMI tends to be obscure and my experience says such things are hard to support long-term. I would either work at the Windows API level, or possibly design a service that performs the desired actions access this service as needed. Of course, you will need to install this service on each machine you need to control. Both approaches have merit. The WinAPI approach pretty much guarantees you don't invent any new security holes and is simpler initially. The service approach should make the application faster and required less network traffic. I am sure you can think of others easily. You still have to have the necessary permissions, network ports, etc. regardless of the approach. E.g., WMI is usually blocked by firewalls and you still run as some NT process. Sorry, not really an answer as such -- meant as a long comment. ADDED Re: API programming, though you have no Windows API experience, I expect you find it familiar for tasks such as you describe, i.e., reading and writing files, scanning directories are nothing unique to Windows. You only need to learn about the parts of the API that interest you. Once you create the appropriate security contexts and start your client process, there is nothing service-oriented in the, i.e., your can simply open and close files, etc., ignoring that fact that the files are remote, other than server name being included in the UNC name of the file/folder location.

I'm about to start working on a project where a Python script is able to remote into a Windows Server and read a bunch of text files in a certain directory. I was planning on using a module called WMI as that is the only way I have been able to successfully remotely access a windows server using Python, But upon further research I'm not sure i am going to be using this module. The only problem is that, these text files are constantly updating about every 2 seconds and I'm afraid that the script will crash if it comes into an MutEx error where it tries to open the file while it is being rewritten. The only thing I can think of is creating a new directory, copying all the files (via script) into this directory in the state that they are in and reading them from there; and just constantly overwriting these ones with the new ones once it finishes checking all of the old ones. Unfortunately I don't know how to execute this correctly, or efficiently. How can I go about doing this? Which python module would be best for this execution?

It'll be either the default interpreter (the top one at the preferences > pydev > interpreter) or the one that's configured for the project (if you select the project > alt+enter > pydev-interpreter/grammar you can let 'default' or select a different one). After you've done a launch, you can go to run > run configurations and change it for the created launch.

When I press CTRL+F9 to run tests in Pydev, which interpreter does it use? For example, I have Python 2.7 and Python 3.3 installed. When I run scripts in the console by pressing CTRL+Shift+Enter, a window pops up that lets me choose interpreter. But this does not happen when running tests.

How to disable creation of $VIRTUAL_ENV/bin/python for python3 virtualenvs?

The purpose of the virtual env is to allow the use of required version as default. That's why you see the symbolic link created. If you want both (i.e no symbolic link python -> /usr/bin/python3) then do not create virtual env

I develop Python3 on GNU/Linux, but my system has two interpreters installed: python2 -> /usr/bin/python python3 -> /usr/bin/python3 (AFAIK: This is normal on a Linux box, other installed applications frequently depend upon different versions of Python: either 2 or 3.) When I create new virtual environments for Python3, I notice the $VIRTUAL_ENV/bin folder has (at least) two python binaries: $VIRTUAL_ENV/bin/python3 -> copied from /usr/bin/python3 $VIRTUAL_ENV/bin/python-> symlink to $VIRTUAL_ENV/bin/python3 I don't want the python symlink, as it hides my Python2 interpreter in /usr/bin/python. Is there a way to disable the creation of symlink python in the new Python3 virtual environment? (For the time being, I run virtualenv, then manually delete $VIRTUAL_ENV/bin/python myself.)

Version 2.x and 3.x happily live together - that is no problem. But the versions in /usr/bin and /usr/local/bin will give you problems: The 'home'compiled version always installs in /usr/local/bin unless you specify the prefix on compilation. System-installed version normally install in /usr/bin. If you call python3, you will only execute the first one found - probably /usr/local/bin/python3. Test this with which python3 The real problem in that you now have two python3.x/site-packages (one in /usr/lib or /usr/lib64, and the other in /usr/local/lib[64]), and installing new modules will update only one of them. (unless you install them twice). I'd suggest that you uninstall the self-compiled one (3.4.0), using make uninstall in the source directory. To be clear: I believe there is no problem in having a 2.7 in /usr and 3.x in /usr/local.

In Ubuntu, I used to have (two hours ago) three versions of python : 2.7 and 3.4.0 installed by default in 'usr/bin' 3.4.3 that I built manually from the official source-code, which I found was in 'usr/local/bin' (that means, at a certain point i was able to run the tree versions of python at the same time) But now, the 3.4.0 version has become a 3.4.3, now i have a 2.7 and two 3.4.3 (one in '/usr/bin' and the other in '/usr/local/bin') This happened while i was experimenting with PIP. So I'm not able to retrace what I actually did. My questions are : Why building the 3.4.3 didn't upgrade the existing 3.4.0, but instead it made a new installation in '/usr/local/bin' ? What do you think actually happened that upgraded the 3.4.0 to a 3.4.3 ? Is it 'okay' to have two installations of the same version (3.4.3) of python in my system ?

The version 2.7 and 3.4 are your distribution official pythons. To upgrade their versions, Ubuntu should release new packages for them. When you install a new python by yourself it goes to /usr/local/bin. I don't recommend having two similar pythons on your system, it will probably be difficult to know whether a package is installed into either or the site-packages. You would have to be careful with pip too. I suggest you remove the pythons installed with apt-get and keep yours in /usr/local/bin.

You need to recheck that the files on your laptop and make sure: The files actually exist / are the correct files. They are in the directory you are trying to access them from. The file names are spelled correctly. If the system could not find the file specified it means something is missing / misplaced, or the file you are trying to access is not spelled the same as the one you actually want. Its most likely a simple error that could be found by just looking over everything and making sure its all the same as your desktop.

Each process has its own environment. When a process starts another process, the new process gets a (eventually modified) copy of its parent environment. The rule is : a process can modify its own environment - this modifications will be inherited by child processes started later a process can modify (at start time) the environment of its child processes a process can never modify its parent's environment (*) So when you start a Python script from a cmd.exe : the script can change its own environment and those changes will be visible by all subsequent commands of the script and all its children the script cannot change the environment for its parent cmd.exe nor for subsequent commands of that cmd.exe If you need to execute other batch commands after changing the environment, you will have to start a new cmd.exe for the python script and have this new shell execute the other commands, or directly execute a .bat file (both via subprocessmodule). setx is a completely different thing : it updates the default environmnent that is given to processes started from windows explorer (including cmd.exe). That environment is stored permanently in Windows registry, and every change to it is broadcasted to all active processes ... that monitors it. Any windows GUI application can process it (and explorer does - that's how every explorer window know immediatly what is the current default environment), but console applications normaly do not. (*) well it used to be possible for .com executable in old MS/DOS system and was even documented. It should be possible on Windows recent system through WriteProcessMemory API call but is absolutely non documented (thanks to eryksun for noticing)

i have a Python script here and it is called from the Windows CMD. It is executing some commands and also changing the Windows environment variables. Now after i changed them with the command "setx". I have to restart another Shell so the new variables are loaded into it. Is it possible that the main shell from which i called my script can update the variables itself ? Or is it possible to start another shell with the new variables and the script will continue in the new opened shell ? Thanks

You can't change the value of a environment variable. Allow me to clarify: environment variables represent the variables set on the environment of a process when that process starts. From the point-of-view of the new process, its environment is unchanging. Changing a variable on the environment (the process' parent) will not change the value of the environment variable seen by the process. Changing a variable on the process will not make it's environment see the change. So, what can you change? Variables set on your process. This is achieved in python by changing os.environ, or using set on the shell. Any changes will be seen by your process and any children you make (os.system, subprocess, most commands on the shell). Variables set by the system (what SetX does). These changes will be seen by any new process launched directly by the system (Explorer, in Windows) after you change them.

Im trying to find a module that will allow me to run a script locally that will: 1. Open a text file on a remote Windows Machine 2. Read the lines of the text file 3. Store the lines in a variable and be able to process the data. This is absolutely no problem on a Linux machine via SSH, but I have no clue what module to use for a remote Windows machine. I can connect no problem and run commands on a remote Windows machine via WMI,but WMI does not have a way to read/write to files. Are there any modules out there that I can install to achieve this process?

(Spyder dev here) There is no simple way to do what you ask for, at least for the Python version that comes with Spyder. I imagine you downloaded and installed our DMG package. That package comes with its own Python version as part of the application (along with several important scientific packages), so it can't be removed because that would imply to remove Spyder itself :-) I don't know how you installed IDL(E?), so I can't advise you on how to remove it.

I have installed the Python IDE Spyder. For me it's a great development environment. Some how in this process I have managed to install three versions of Python on my system.These can be located as following: Version 2.7.6 from the OS X Terminal; Version 2.7.8 from the Spyder Console; and Version 2.7.9rc1 from an IDL window. The problem I have is (I think) that the multiple versions are preventing Spyder from working correctly. So how do I confirm that 2.7.6 is the latest version supported by Apple and is there a simple way ('silver bullet') to remove other versions from my system. I hope this is the correct forum for this question. If not I would appreciate suggestions where I could go for help. I want to keep my life simple and to develop python software in the Spyder IDE. I am not an OS X guru and I really don't want to get into a heavy duty command line action. To that end I just want to delete/uninstall the 'unofficial versions' of Python. Surely there must be an easy way to do this - perhaps 'pip uninstall Python-2.7.9rc1' or some such. The problem is that I am hesitant to try this due to the fear that it will crash my system. Help on this would be greatly appreciated.

You can attach the debugger to a python process launched from terminal: Use Menu Tools --> Attach to process then select python process to debug. If you want to debug a file installed in site-packages you may need to open the file from its original location. You can to pause the program manually from debugger and inspect the suspended Thread to find your source file.

I know how to set-up run configurations to pass parameters to a specific python script. There are several entry points, I don't want a run configuration for each one do I? What I want to do instead is launch a python script from a command line shell script and be able to attach the PyCharm debugger to the python script that is executed and have it stop at break points. I've tried to use a pre-launch condition of a utility python script that will sleep for 10 seconds so I can attempt to "attach to process" of the python script. That didn't work. I tried to import pdb and settrace to see if that would stop it for attaching to the process, but that looks to be command line debugging specific only. Any clues would be appreciated. Thanks!

Esky uses a bootstrapping mechanism that keeps the app safe in the face of failed or partial updates. The top level executable is the one you should be running, it does all the business of managing what version to run. Once it has decided what to run it will open up the exe for the correct version.

Will using memcache reduce my instance memory?

python-2.7,google-app-engine,memcached

Moving objects to and from Memcache will have no impact on your memory unless you destroy these objects in your Java code or empty collections. A bigger problem is that memcache entities are limited to 1MB, and memcache is not guaranteed. The first of these limitations means that you cannot push very large objects into Memcache. The second limitations means that you cannot easily replace, for example, a HashMap with memcache - it's impossible to tell if getValue() returns null because an object is not present or because it was bumped out of memcache. So you will have to make an extra call each time to a datastore to see if an object is really not present.

I'm currently running into soft memory errors on my Google App Engine app because of high memory usage. A number of large objects are driving memory usage sky high. I thought perhaps if I set and recalled them from memcache maybe that might reduce overall memory usage. Reading through the docs this doesn't seem to be the case, and that the benefit of memcache is to reduce HRD queries. Does memcache impact overall memory positively or negatively? Edit: I know I can upgrade the instance class to F2 but I'm trying to see if I can remain on the least expensive while reducing memory.

I figured out the answer in case anybody else runs into a similar issue; You actually dont even need WMI and can be run directly from command prompt: if you are in the same network you can issue a command via command prompt with the following format: taskkill /s [Computer name or IP] /u [USER or DOMAIN\USER] /p Password /pid [The process to kill i.e. notepad.exe] This will take a few moments but will eventuall kill the process that is running.

I am setting up a production server for the first time and would like to make sure I only have what I need for security prepress. By "interactions" since I'm also new to programming, I think I mean "API calls". Do I need mysql-client on a Linux (Debian) server to be able to 'talk' to mysql with any programming language? As I think there isn't any point installing the client on the production server if I can remotely send commands from mysql-client on my Mac.

What you are looking for is a GUI tool-kit with bindings to python. Tkinter is the de facto standard for python GUI and is cross platform. Qt is also a popular choice but the license is more restrictive then Tkinter but will allow you to transition into C++ programming with Qt easier if that is something you may want to do down the road. The choice up to you.

I am pretty familiar with building web based apps using python django on my linux machine. But when I decided to try my hand at building desktop applications that can run on windows/linux I didn't know where to begin. I know I can surely build windows desktop application on windows machine. But I am pretty comfortable with linux and don't want to get out of that comfort zone. Can anyone guide me as to what tools can I begin with to develop a simple windows desktop application. I would target windows 7 for starters. Any guidance is hugely appreciated.

The problem is that this file is only written for Python 2 but you are using Python 3. You should use Anaconda (vs. Anaconda3), or create a Python 2 environment with conda with conda create -n py2 anaconda python=2 and activate it with activate py2.

I have a sample python script: sample.py. The script takes the argument as the user name and password to connect to some remote server. When I run the script sample.py --username --password , the password is being logged in linux messages files. I understand this is a linux behavior, but wondering if we can do anything within my script to avoid this logging. One way I can think is to provide password in an interactive way. Any other suggestions?

App engine Datastore cache or memcache

The 'Datastore caching' you refer to is implemented using memcache under the hood anyway, so you won't gain from additional explicit caching of these entities. Python's ndb API and Java's Objectify both provide memcache-based automated caching for exactly this scenario. Of course, you can still use memcache independently for additional application caching.

I have read that the datastore read request in the App engine get cached and subsequent reads performed on the same entity are fast. So if i read an entity from datastore, are there any tangible benefits of storing the entity in the memcache explicitly for later fetches? Or would the datastore caching serve with sufficient efficiency?

python,google-app-engine

I'm not entirely clear on what you're looking for, but you can retrieve that type of information from the WSGI environmental variables. The method of retrieving them varies with WSGI servers, and the number of variables made available to your application depends on the web server configuration. That being said, getting client IP address is a common task and there is likely a method on the request object of the web framework you are using. What framework are you using?

All http requests go to my 3-level domain, and IP of this domain isn't fixed, it changes rather frequently and can be different on different computers at the same moment. Can I somehow find out, what IP address client is requesting now? Thank you!

I'm running a flask application using nginx and uwsgi and I noticed when I tail the logs for uwsgi it looks like its just constantly polling my app when I'm doing nothing. It also seems like it's cycling through the cores on my machine with each request so I see this in the logs. [pid: 27182|app: 0|req: 557/784] {26 vars in 254 bytes} [09:33:38 2015] GET / => generated 1337 bytes in 11 msecs ( 200) 3 headers in 238 bytes (1 switches on core 0) [pid: 27182|app: 0|req: 558/785]{26 vars in 254 bytes} [09:33:42 2015] GET / => generated 1337 bytes in 11 msecs ( 200) 3 headers in 238 bytes (1 switches on core 1) [pid: 27182|app: 0|req: 559/786] {26 vars in 254 bytes} [09:33:43 2015] GET / => generated 1337 bytes in 11 msecs ( 200) 3 headers in 238 bytes (1 switches on core 2) [pid: 27182|app: 0|req: 560/787] {26 vars in 254 bytes} [09:33:47 2015] GET / => generated 1337 bytes in 11 msecs ( 200) 3 headers in 238 bytes (1 switches on core 3) Nginx shows something similar. It's just constantly issuing a request to my app. It's only doing this when nginx is on. If I stop nginx the polling stops. My app is up and working but I don't know why this is happening. Is this normal behavior for nginx/uwsgi when using the uwsgi protocol? EDIT Im also using uwsgi in emperor mode

Passing dictionary values in python as command line inputs to c++ code

You can't do that unless you relax one of the restrictions. Relax the python dict requirement: The command line has a well defined text arguments interface, which can easily handle all the info. You can pass the json filename, the str representation of the dict, or pass name-value pairs as command line arguments. Relax the system call requirement: Rather than building an executable from the c++ code, you can build a python c++ extension. The c++ code can export functions that take a python dict. Relax the c++ requirement: Obviously you could code it in python.

I'm using Eclipse Luna and the latest pydev with it. I have wxpython 3.0 installed. First, I could import wx and I tried in the console to print version, perfect, but then I do import wx.lib.pubsub -- it says unresolved. I try other variations, no dice, so I have to go into the properties of my project and add wx manually, then it worked. Second, now all my CallAfter calls are underlined red, undefined variable from import. I know callAfter used to be it, so I tried that too, it tries to autocomplete to it -- but then underlines it. I know in 3.0, CallAfter is capitalized. Even if it wasn't, Eclipse tries to autocomplete to an old version and then says it's still bad. I've never seen that before, I'm confused. Does anyone know what I'm doign incorrectly? EDIT: Even weirder -- I use the console inside pydev eclipse, it autocompletes to normal CallAfter and doesn't throw any errors.

I would recommend RabbitMQ or Redis (RabbitMQ preferred because it is a very mature technology and insanely reliable). ZMQ is an option if you want a single hop messaging system instead of a brokered messaging system such as RabbitMQ but ZMQ is harder to use than RabbitMQ. Depending on how you want to utilize the message passing (is it a task dispatch in which case you can use Celery or if you need a slightly more low-level access in which case use Kombu with librabbitmq transport )

I am implementing a small distributed system (in Python) with nodes behind firewalls. What is the easiest way to pass messages between the nodes under the following restrictions: I don't want to open any ports or punch holes in the firewall Also, I don't want to export/forward any internal ports outside my network Time delay less than, say 5 minutes, is acceptable, but closer to real time would be nice, if possible. 1+2 → I need to use a third party, accessible by all my nodes. From this follows, that I probably also want to use encryption Solutions considered: Email - by setting up separate or a shared free email accounts (e.g. Gmail) which each client connects to using IMAP/SMTP Google docs - using a shared online spreadsheet (e.g. Google docs) and some python library for accessing/changing cells using a polling mechanism XMPP using connections to a third party server IRC Renting a cheap 5$ VPS and setting up a Zero-MQ publish-subscribe node (or any other protocol) forwarded over SSH and having all nodes connect to it Are there any other public (free) accessible message queues available (or platforms that can be misused as a message queue)? I am aware of the solution of setting up my own message broker (RabbitMQ, Mosquito) etc and make it accessible to my nodes somehow (ssh-forwardning to a third host etc). But my questions is primarily about any solution that doesn't require me to do that, i.e. any solutions that utilizes already available/accessible third party infrastructure. (i.e. are there any public message brokers I can use?)

I'm going to answer my own question, since I have found a solution to my problem. I had previously run apt-get upgrade on my system after setting my debian release to jessie. This did not replace python 3.2 though. What did replace it was running apt-get dist-upgrade; after that apt-get autoremove removed python 3.2. I doubt that this could be a problem, since I hadn't installed any external libraries.

I am currently experiencing an issue in my GAE app with sending requests to non-default modules. Every request throws an error in the logs saying: Request attempted to contact a stopped backend. When I try to access the module directly through the browser, I get: The requested URL / was not found on this server. I attempted to stop and start the "backend" modules a few times to no avail. I also tried changing the default version for the module to a previous working version, but the requests from my front-end are still hitting the "new", non-default version. When I try to access a previous version of the module through the browser, it does work however. One final symptom: I am able to upload my non-default modules fine, but cannot upload my default front-end module. The process continually says "Checking if deployment succeeded...Will check again in 60 seconds.", even after rolling back the update. I Googled the error from the logs and found almost literally nothing. Anyone have any idea what's going on here, or how to fix it?

If you use github with a private repo you will have to create a SSH deploy key and add the private key to your app folder for builds. pip install git+git://github.com/myuser/foo.git@v123 Alternatively, you can mount a pip-cache folder from host into container and do pip install from that folder. You'd have to keep the python packages in the cache dir with your app. pip install --no-index --find-links=/my/pip-cache/ you can install python packages to this pip-cache with the following command: pre pip 9.0.1: pip install --download pip-cache/ package1 package2 pip 9.0.1+ (thx for comment @James Hiew): pip install download pip-cache/ package1 package2

I have a fairly large private python package I just finished creating. I'd like to install it as part of my build process for an app in a Docker container (though this isn't so important). The package source is quite large, so ideally I'd avoid downloading/keeping the whole source. Right now, I've been just passing around the package source along with my app, but this is unwieldy and hopefully temporary. What's a better way? git submodule/subtree? I'm pretty new to this.

What is the relationship between virtualenv and pyenv?

58,878

0

python,virtualenv,virtualenvwrapper,pyenv

Short version: virtualenv allows you to create local (per-directory), independent python installations by cloning from existing ones pyenv allows you to install (build from source) different versions of Python alongside each other; you can then clone them with virtualenv or use pyenv to select which one to run at any given time Longer version: Virtualenv allows you to create a custom Python installation e.g. in a subdirectory of your project. This is done by cloning from an existing Python installation somewhere on your system (some files are copied, some are reused/shared to save space). Each of your projects can thus have their own python (or even several) under their respective virtualenv. It is perfectly fine for some/all virtualenvs to even have the same version of python (e.g. 3.8.5) without conflict - they live separately and don't know about each other. If you want to use any of those pythons from shell, you have to activate it (by running a script which will temporarily modify your PATH to ensure that that virtualenv's bin/ directory comes first). From that point, calling python (or pip etc.) will invoke that virtualenv's version until you deactivate it (which restores the PATH). It is also possible to call into a virtualenv Python using its absolute path - this can be useful e.g. when invoking Python from a script. Pyenv operates on a wider scale than virtualenv. It is used to install (build from source) arbitrary versions of Python (it holds a register of available versions). By default, they're all installed alongside each other under ~/.pyenv, so they're "more global" than virtualenv. Then, it allows you to configure which version of Python to run when you use the python command (without virtualenv). This can be done at a global level or, separately, per directory (by placing a .python-version file in a directory). It's done by prepending pyenv's shim python script to your PATH (permanently, unlike in virtualenv) which then decides which "real" python to invoke. You can even configure pyenv to call into one of your virtualenv pythons (by using the pyenv-virtualenv plugin). You can also duplicate Python versions (by giving them different names) and let them diverge. Using pyenv can be a convenient way of installing Python for subsequent virtualenv use.

install numpy for python 3.4 in ubuntu

You're close, to update a package for python3.4 you have to sudo pip3 install -U numpy (note the pip3). It might be the case that you still have to install pip3 first (not sure if it is bundled). Probably for that you have to sudo apt-get install python-pip3 or something. If you have a recent Ubuntu (I believe starting from 14.10), then you already have python 3.4 when you first boot up Ubuntu, as well as pip3 pre-installed. You can also install through ubuntu's package manager, but if you want an OS independent way, you can just use pip3.

I have python 2.7, and I installed beside it python 3.4, but python 3.4 has not numpy package. When I use sudo pip install -U numpy, it install it in python2.7 location. How can I install numpy for python 3.4 in a machine that has already python 2.7?

Python script fallback to second server

Could you shutdown the script on your VPS, copy the cache files over the the Pi and run the script there? Then do the reverse when you want to move it back to the VPS. You could possibly run the script on both systems, but then you'd need to synchronize between them which sounds like a lot of unnecessary work. For instance you could run a third server that you can check with to see if you've sent something yet, but you would need to be able to lock items on there so you don't have a race condition between your two scripts.

I have a Python script that manages Pushbullet channels for Nexus Android device factory images. It runs on my VPS (cron job that runs every 10 minutes), but my provider has warned that there may be intermittent downtime over the next several days. The VPS is running Ubuntu Server 15.04. I have a Raspberry Pi that's always on, and I can easily modify the script so that it works independently on both the VPS and the Pi. I would like the primary functionality to exist on the VPS, but I want to fall back to the Pi if the VPS goes down. What would be the best way to facilitate this handoff between the two systems (in both directions)? The Pi is running Raspbian Wheezy. Additionally, the script uses urlwatch to actually watch the requisite page for updates. It keeps a cache file on the local system for each URL. If the Pi takes over and determines a change is made, it will notify the Pushbullet channel(s) as it should. When the VPS comes back up and takes over, it will have the old cache files and will notify the channel(s) again, which I want to avoid. So: How can I properly run the script on whichever system happens to be up at the moment (preferring the VPS), and how can I manage the urlwatch caches between the two systems?

Probably the links are not working To solve this, backup your current python link: cp /usr/bin/python ~/Desktop Remove the old soft link and create a new soft link pointing to Python 3.4.3 installation: rm -f /usr/bin/python ln -s /System/Library/Frameworks/Python.framework/Versions/3.4/bin/python3.4 /usr/bin/python

I installed Python 3.4.3 and then installed Python 2.7.9 on Mac Air. If I run Python on a command line, it shows Python 2.7.9. I removed Python 2.7.9, it still shows Python 2.7.9. What is the problem? Thanks.

Celery worker: periodic local background task

One possible method I thought of, though not ideal, is to patch the celery.worker.heartbeat Heart() class. Since we already use heartbeats, the class allows for a simple modification to its start() method (add another self.timer.call_repeatedly() entry), or an additional self.eventer.on_enabled.add() __init__ entry which references a new method that also uses self.timer.call_repeatedly() to perform a periodic task.

Is there any Celery functionality or preferred way of executing periodic background tasks locally when using a single worker? Sort of like a background thread, but scheduled and handled by Celery? celery.beat doesn't seem suitable as it appears to be simply tied to a consumer (so could run on any server) - that's the type of scheduling I was after, but just a task that is always run locally on each server running this worker (the task does some cleanup and stats relating to the main task the worker handles). I may be going about this the wrong way, but I'm confined to implementing this within a celery worker daemon.

Install the "idle" package. Many distros break the core python installation into several pieces, and idle is usually one that is packaged separately.

IIS access to a remote server in same domain

Since you provide no example code or describe what you are doing... There are a few things to consider. Anything running in the context of a webpage in IIS is running in a different context than a logged in user. The first part of that is simply what file system level permissions might be different for the IIS user account. The proper way you want to handle that is by assigning the necessary changes at the filesystem level for the IIS user. Do not change the IIS user if you do not understand the ramifications of doing that. The next part is that certain operations cannot be done in the context of the IIS user account (regardless of account permissions), because there are certain things that only a logged in user with access to the console/desktop can do. Certain operations called from IIS are purposely blocked (shell.execute) regardless of permissions, account used, etc. This occurs in versions of IIS in Windows Server 2008 and later and is done for security.

I have a server A where some logs are saved, and another server B with a web server (IIS) on it. I can access serverA from Windows Explorer with zero problems, but when I want to access it from serverB with some PHP code, it doesn't work. I made a python script that accesses the file from serverA on serverB. It works if I run that script from CMD, but when I run that script from PHP code it doesn't work anymore. I run IIS server as a domain account that has access on serverA I try to run that as LocalService, NetworkService, System, LocalUser but no success. That script is a simple open command, so problem it's not from python.

I have an hourly cron job which has been running in Openshift free gear for almost a year and has been no problem. But the past 2 days, cron job stops running automatically. I have been googling around and still cannot find what went wrong. Here are what I have checked/done to date the service I use to keep the site alive is still up and running as normal. So it is not a case of being idle. force restart the app. Cron job still not started automatically as it used to. fake changes to cron script file and push to Openshift. Still not fixed this. log files looks ok Mon May 4 13:01:07 EDT 2015: START hourly cron run Mon May 4 13:01:29 EDT 2015: END hourly cron run - status=0 Any advice or pointer as to why it just stop working when there is no change to the app. Thank you.

You can define the start command in a file called Procfile. Create the Procfile in the root of your app code that you push to Bluemix. The contents of the Procfile should look like this: web: python3 appname.py where appname.py is the nameof your python script to run

You don't need to create a py2exe executable for this, you can simply run the Python executable itself (assuming it's installed of course), passing the name of your script as an argument. And one way to do that is to use the task scheduler, which can create tasks to be run at boot time, under any user account you have access to.

There are two good reasons. If your program crashes or is unexpectedly terminated, then output files may be corrupted. It's good practice to close what you open.

I know it is a good habit of using close to close a file if not used any more in Python. I have tried to open a large number of open files, and not close them (in the same Python process), but not see any exceptions or errors. I have tried both Mac and Linux. So, just wondering if Python is smart enough to manage file handle to close/reuse them automatically, so that we do not need to care about file close? thanks in advance, Lin

Creating an alias in your ~/bashrc is a good approach. It sounds like you have not run source ~/.bashrc after you have edited it. Make sure to run this command. Also keep it mind that when you run sudo python your_script.py it will not use your alias (because you are running as the root, not at the ec2-user). Make sure to not change your default python, it could break several programs in your linux distributions (again, using an alias in your ~/bashrc is good).

Upon running python in any dir in my amazon EC2 instance, I get the following printout on first line: Python 2.6.9 (unknown, todays_date). Upon going to /usr/bin and running python27, I get this printout on first line: Python 2.7.9 (default, todays_date). This is a problem because the code that I have only works with Python 2.6.9, and it seems as though my default is Python 2.7.9. I have tried the following things to set default to 2.6: 1) Editing ~/.bashrc and creating an alias for python to point to 2.6 2) Editing ~/.bashrc and exporting the python path 3) Hopelessly scrolling through the /etc folder looking for any kind of file that can reset the default python What the hell is going on?!?! This might be EC2 specific, but I think my main problem is that upon running /usr/bin/python27 I see that it is default on that first line. Even upon running python -V, I get Python 2.6. And upon running which python I get /usr/bin/python, but that is not the default that the EC2 instance runs when it attempts to execute my code. I know this because the EC2 prints out Python/2.7.9 in the error log before showing my errors.
