if ntop installed look example files usrsharentoppython ubuntu package version least if epydoc installed run make within usrsharentoppythondocs directory generate documentation once about online documentation python ntop engine python api link work correctly seems like bug requires work part user fix link

can anyone point towards tutorials using python api ntop luca deris paper in web interfaces online documentation python engine i think link error does anyone access document repost online

yes exact way wrote your code fine

for example mymessage dear hello name jj print mymessage name does python feature accomplishing something like code

python really concept constant find c so fairly good approach i would actually argue one example consenting adults hold terribly well think language awesome constant every would nice

for example mymessage dear hello name jj print mymessage name does python feature accomplishing something like code

your code correct i believe preferred way mymessage dear hello mymessageformat jj dear jj hello preferred possible future replacement operator format method as mentioned mark lutz learning python fourth edition format method features found expression make substitution values explicit trades operator arguably mnemonic method name support different syntax single multiple substitution value cases later book risk python developers may deprecate expression favor format method future in fact note effect python manuals

for example mymessage dear hello name jj print mymessage name does python feature accomplishing something like code

yield sucks continuations better actually python yield continuation what continuation a continuation saving present point execution state one continue point later that precisely python yield also precisely implemented it understanding python continuations delimited however i know much i might wrong fact nor i know implications may scala continuation work runtime fact continuations library java work stuff bytecode runtime free constrains scala continuation scala continuation entirely done compile time require quite bit work it also requires code continued prepared compiler and forcomprehensions work a statement like x xs procx if translated xsforeachx procx where foreach method xs class unfortunately xs class long compiled cannot modified supporting continuation as side note also scala continue aside yes duplicate question yes find different way write code

i writing code phd research starting use scala i often text processing i used python whose yield statement extremely useful implementing complex iterators large often irregularly structured text files similar constructs exist languages eg c good reason yes i know previous threads but look like hackedup least badly explained solutions clearly work well often unclear limitations i would like write code something like import generator def yieldvaluesfilestring generate x sourcefromfilefilegetlines scala already using yield keyword givesomething field rsplitx field contains subfield rsplitfield givesubfield else scala continue imo considered bug scala preferred fieldstartswith continue actual need indent following code fieldstartswith val somecalculation stuff somecalculation ampamp fieldstartswithr giver givefieldslice else typically good deal code handle different cases givefield i like see code implements generate give btw give named yield scala taken keyword already i gather reasons i understand scala continuations may work inside statement if generate supply equivalent function works close possible statement iterator code yield almost inevitably sits inside loop please i would prefer get following answers yield sucks continuations better yes general continuations but hella hard understand time iterator want need if scala provides lots powerful tools hard use practice language succeed this duplicate please see comments you rewrite code using streams continuations recursion etc etc please see i also add technically need loops either for matter technically absolutely everything ever need using ski combinators your function long break smaller pieces need yield you production code anyway first need yield doubtful case second production code third text processing like often breaking function smaller pieces especially language forces lacks useful constructs makes code harder understand rewrite code function passed technically yes but result longer iterator chaining iterators much nicer chaining functions in general language force write unnatural style certainly scala creators believe general since provide shitloads syntactic sugar rewrite code way cool awesome way i thought sorry sarcasm previous list typical responses i seen similar scala questions stack overflow thanks help

if i understand correctly actually swapping instances class classes instance state kept two possible places slots dict if swap basically swapped instances retaining original name bindings one caveat class cannot immutable must define hash instances already members set keys dictionary would become irretrievable if i think i would swap method class method instead i think would read easier class somebigclass staticmethod def swapdictinstancea instanceb instanceadict instancebdict instancebdict instanceadict classmethod def swapslotcls instancea instanceb values attr clsslots valuesappend attr getattrinstancea attr getattrinstanceb attr attr val val values setattrinstancea attr val setattrinstanceb attr val later somebigclassswapdictthisinstance otherinstance somebigclassswapslotthisinstance otherinstance why if instances bound names consider frubbah somebigclassattrhi mom zikroid somebigclassattr hi dad somebigclassswapdictfrubbah zikroid after swap potentially everything thought knew zikroid changed

i big class lots members quite references instances class lying around unfortunately reasonable reasons references wrong way around instead recreating finding updating everywhere objects referenced adding extra level indirection time i access class individually swapping members i defined method def swapself assertisinstanceother selfclass selfdict otherdict otherdict selfdict i instanceaswapinstanceb references instancea everywhere instancea instanceb the question it seems work fine i use slots feels like might reason i here actual use case i type implements comparison operators necessarily expensive way i various sorted datastructures containing objects type when i something one objects i know comparison order changed order data structures restored swapping modified object next bigger one

as delnan already said comment able use real binary numbers mean bitforbit equivalent memory usage integers longs course real binary numbers meaning address individual bits using bitwise operators easily hidden class also long objects become arbitrarily large ie use simulate arbitrarily large bitsets it going fast python difficult either good start using binary generation scheme following reduce lambda p b b p p randomrandint range of course random supports arbitrarily large upper boundaries r randomrandint this entirely since individual binary digits independent way independent create digit then knowing prngs work really independent case either if concern probably use random module hardware rng

so if know basic c language your problem print element array so go like array int foriii print print array wrong similarly case iterating entrieslist assigning element variable entries now play entries entries entrieslist ibnameib entriesname br img srcimages entriespicture height widthimgbr ibingredientsib entriesingredients br pi entriesdescription ip endfor and ofcourse carl given better solution getting latest recipes case models

you use producerconsumer threads the threads synchronized using queuequeue edit example producerconsumer system threading import thread queue import queue def producequeue nitems rangenitems queueputd print put queueformatd def consumequeue nitems nitems you need sort stop condition queueget print got queueformatd def startproducerandconsumerwait q queue consumerthread threadtarget consume args q producerthread threadtarget produce args q producerthreadstart consumerthreadstart wait producerthreadjoin consumerthreadjoin name main startproducerandconsumertrue as see execute everything consumed correct order

imagine text file mb i reading char char extracting useful information i actually main functions one reading file second extracting info something like def readerpath f openpath r source fread fclose true i read char char call function extractor def extractors i extract useful information now goal continue read extractor working so basicaly question appropriate way accomplish goal

groups empty since capturing groups httpdocspythonorglibraryrehtmlrematchobjectgroups group always returns whole text matched regardless captured group edited

when i run code print researchr groups i get result however group gives match shouldn groups give something containing match update thanks answers so means i research subgroups i use groups get match

creating closure self technically bind function alternative way solving similar underlying problem here trivial example selfmethod lambda self lambda args selfdoargsself

in python way bind unbound method without calling i writing wxpython program certain class i decided nice group data buttons together classlevel list tuples like class mywidgetwxwindow buttons ok onok cancel oncancel def setupself text handler mywidgetbuttons this following line problem line b wxbuttonparent labeltextbindwxevtbutton handler the problem since values handler unbound methods program explodes spectacular blaze i weep i looking around online solution seems like relatively straightforward solvable problem unfortunately i find anything right i using functoolspartial work around anyone know cleanfeeling healthy pythonic way bind unbound method instance continue passing around without calling

the reason capturing groups since use pattern httpdocspythonorglibraryrehtmlrematchobjectgroups and group returns entire search result even capturing groups httpdocspythonorglibraryrehtmlrematchobjectgroup

when i run code print researchr groups i get result however group gives match shouldn groups give something containing match update thanks answers so means i research subgroups i use groups get match

you groups regex therefore get empty list result try researchr groups with brackets creating capturing group result matches part pattern stored group then get result

when i run code print researchr groups i get result however group gives match shouldn groups give something containing match update thanks answers so means i research subgroups i use groups get match

to best knowledge groups returns tuple remembered groups ie groups regular expression enclosed parentheses so write print researchr groups would get response in general groups return tuple groups objects regular expression enclosed within parentheses

when i run code print researchr groups i get result however group gives match shouldn groups give something containing match update thanks answers so means i research subgroups i use groups get match

it sounds like mean line profiler something measures time spent ie instrumenting within line i hope mean time wallclock time real goodsize software look cpu time going missing lot another way stacksampling wallclock time zoom ltprof profilers since every line stack sample localized line code using map pdb file way debuggers need parse modify source the percent time taken line code simply percent stack samples containing since working line level need distinguish exclusive self time inclusive time this line percent time active matters whether call another function call blind system function call microcode the advantage looking percents instead absolute times need worry app slowed either sampling competition processes things affect percents much also worry recursion if line code recursive function appears sample ok it still counts one sample containing line the reason ok line code could somehow made take time removing sample would occurred therefore samples containing line would removed sample set program total time would decrease amount fraction samples removed that irrespective recursion you also need count many times line code executed number matters locating code optimize percent time active here explanation issues

i trying determine necessary write line profiler language like available python matlab a naive way interpret line profiler assume one insert time logging around every line definition line dependent parser handles whitespace first problem it seems one needs use parse tree insert timings around individual nodes is conclusion correct does line profiler require parse tree needed beyond time logging update offering bounty question still unresolved update here link well known python line profiler case helpful answering question i yet able make heads tails behavior relative parsing i afraid code matlab profiler accessible also note one could say manually decorating input code would eliminate need parse tree automatic profiler update although question language agnostic arose i thinking creating tool r unless exists i found update regarding use line profiler versus call stack profiler post relating using call stack profiler rprof case exemplifies painful work call stack rather directly analyze things via line profiler
