i stumbled upon sj brown tutorial making games past it great page one best i read however like i like calls isinstance fact listeners receive events first isinstance slower checking two strings equals i ended storing name events test name rather class but still notify function battery itching felt like waste time we two optimizations most listeners interested types events for performance reasons quitevent posted listeners interested notified the event manager keeps track listener wants listen event then avoid going tons statements single notify method one method per type event example class gameloopcontroller def onquiteventself event directly called event manager quitevent posted i call event handler selfrunning false because i want developer type little possible i made following thing when listener registered event manager event manager scans methods listener when one method starts prefix like looks rest quitevent binds name method later event manager pumps event list looks event class name quitevent it knows name therefore directly call corresponding event handlers directly the developer nothing adding onwhateverevent methods working it drawbacks if i make typo name handler onrunphysicsevent instead onphysicsranevent example handler never called i wonder but i know trick i wonder long i cannot add event handler listener registered i must unregister reregister indeed events handlers scanned registration then i never anyway i miss despite drawbacks i like much constructor listener explicitly explain event manager wants stay tuned event and execution speed anyway second point when designing event manager want careful very often listener respond event creatingregistering unregisteringdestroying listeners this happens time if think game may break runtimeerror dictionary changed size iteration the code propose iterates copy dictionary protected explosions consequences aware listeners registered event receive event listeners unregistered event still receive

no i believe possible analyse rrule see intersect another one without creating datetime objects essentially asking output algorithm without running algorithm i think noncomputable however certain types rrule possible eg rrule every thursday intersect rrule every tuesday the problematical ones days month days year intersecting days week frequencies never intersect the best bet would rules analytically checkable analytically others generate next year data compare manually the algorithm run fast since cache existing occupied times add rule,i working application looks like google calendar one main difference events intersections events this means two events may share common time even minutes granularity this specially useful calendar store meetings since impossible time two meetings just like google calendar events may created using recurrence rules every friday sunday am pm example so i would like detect overlapping events using rrules pythondateutil module without needing create n datetime objects checking intersection one is possible detect overlapping dates using rrules is anything similar already implemented another library,1

i think could let python keep track function calls parameters instead stack suppose yaml parse tree node represents function call child node parameter also function call could potentially parameters then define function evaluate evaluates node tree follows pseudocode def evaluatenode evaluate parameters call params child node paramsappendevaluatechild make call whatever function node represents passing parameters return nodefunctioncallparams finally call evaluate passing root yaml tree parameter get desired behaviour a slightly different evalapply structure def evaluatenode evaluate parameters call params evaluatechild child node apply whatever function node represents return nodefunctioncallparams,i python library builds special iterators behavior tree nested function calls while api fairly nice lightweight syntax due python could really use declarative dsl here rough sketch i envisioning the dsl using yaml tree sequence doaction doaction select doaction sequence doaction doaction doaction would result following nested function calls visit sequence doaction doaction select doaction sequence doaction doaction doaction i trouble visualizing exactly because dsl must represent tree simple depthfirst traversal seems appropriate but order build nested function calls i turn inside somehow it probably involves something clever intermediary stack somesuch i quite grasp what correct way perform transformation,2

it something regex engines tend able i know python perl using following local matches foofoobarfoobaz z push matches fail xs this specific problem probably solved using regex engine many languages using following technique matches foofoobarfoobaz zgsp push matches prematch prematch refers comes regex matched refers first matched but easily solve specific problem outside regex engine parts split foofoobarfoobaz matches parts push matches join parts join partsparts sorry using perl syntax able get idea translations python welcome,i regex match string multiple overlapping possible ways however seems capture one possible match string i get possible matches i tried finditer success maybe i using wrong the string i trying parse foofoobarfoobaz the regex i using foofoobarfoobaz matches refinditerr matchgroup match matches foofoobar i want match foo foobarfoobaz seems get foofoobar foobaz,1

why surprising retrieving lot records takes lot resources this on process really perrequest basis to answer questions order how much cpu time uses depends nature records result surprising note nearly cpu seconds wallclock seconds also note new billing model rolls charged datastore operations instance hours optimising the admin console shows authoritative figures billed based the appstats figures lower count time spent api calls time spent executing code if set records small fairly static cache instance memory rather fetching time storing memcache if larger dynamic use something like geomodel geographical queries fetch relevant records fetching records always takes amount api cpu time datastore access costs represented actually time taken the new model fixes breaking separate billable operations,when trying optimize query getting store records based location i dumped something strange i think getting large dataset takes alot cpu time basically i records need iterated find stores within users position i got quite high numbers admin console this lead datastore testing resulted interesting numbers getting records i tests methods i ran separately took cpu time admin console appstats resulted production r dbgqlqueryselect key from storerecordsfetch appstats realms cpums apims admin console ms cpums apicpums r dbgqlqueryselect key from storerecordsfetch appstats realms cpums apims admin console ms cpums apicpums r dbgqlqueryselect from storerecordsfetch appstats realms cpums apims admin console ms cpums apicpums r dbgqlqueryselect from storerecordsfetch appstats realms cpums apims admin console ms cpums apicpums r modelstorerecordsallfetch appstats realms cpums apims admin console ms cpums apicpums r modelstorerecordsallfetch appstats realms cpums apims admin console ms cpums apicpums here i take records need fetch my questions should fetch records really take almost cpums apicpums seconds why differences appstas admin console times what calculated quota one could easily get around pushing fetched records memcache protobuf but i curios high usage differences time appstas admin console bonus question how come fetching records always result apicpums,1

c java c etc really strange behaviour regarding instance variables whereby data members fields depending culture belong described within class block belongs instances functions well methods c programmers seem hate term say member functions instead described within block belong class strange confusing actually think a lot people think accept move but actually causes confusion lot beginners assume everything within block belongs instances this leads bizarre experienced programmers questions concerns perinstance overhead methods trouble wrapping heads around whole vtable implementation concept of course mostly teachers collective fault failing explain vtables one implementation failing make clear distinctions classes instances first place python confusion since python functions including methods objects would bizarrely inconsistent compiler make distinction like so happens python intuitively expect everything within class indented block belongs class and yes python classes objects well gives place put class attributes jump standard library hoops use reflectively the absence manifest typing quite liberating so i hear protest actually add data instances well default python restrict adding anything instance it even require make different instances class contain attributes and certainly preallocate single block memory contain object attributes it would able contain references anyway given python pure referencesemantics language c style value types java style primitives but obviously good idea things way usual convention add data time instance constructed add delete attributes when constructed python really constructors cjavac sense absence reserved space means real benefit considering initialization separate task ordinary assignment except course benefit initialization something automatically happens new object so python closest equivalent magic init method automatically called upon newlycreated instances class there another magic method called new behaves like constructor sense responsible actual creation object however nearly every case want delegate base object new calls builtin logic basically give us little pointerball serve object point class definition so real point worrying new almost every case it really analogous overloading operator new class c in body method cstyle initialization lists prereserved data initialize set initial values attributes possibly work based parameters given now want little bit neater things efficiency real concern another trick sleeves use magic slots attribute class specify class attribute names this list strings nothing fancy however still preinitialize anything instance attribute assign this prevents adding attributes names you even still delete attributes object whose class specified slots all happens instances given different internal structure optimize memory usage attribute lookup the slots usage requires derive builtin object type anyway although required python x intended backwardscompatibility purposes ok make code work but make right python first language constantly commenting explain alreadyselfexplanatory things bad idea it distracts user really help learner language either you supposed know class definition looks like need comment tell class definition class definition reading code comments kind help need with whole duck typing thing poor form include data type names variable attribute names you probably protesting i supposed keep track type otherwise without manifest type declaration don the code uses list windows care list windows list windows it cares iterate list windows thus obtain values used certain ways associated windows that duck typing works stop thinking object worry you notice code i put string conversion code house window constructors this serves primitive form typechecking also makes sure forget conversion if someone tries create house id even converted string raise exception easier ask forgiveness permission note actually go way bit python create as actual iteration python iterate actually iterating objects container java c concept well get c standard library although lot people bother we iterate indices useless distracting indirection we need number windowsperhouse values order use need look value turn how id numbers i hear ask simple python provides us function called enumerate gives us index element pairs given input sequence elements it clean lets us explicit need index solve problem purpose index builtin need interpreted like rest python code incur much overhead when memory concern possible use lazyevaluation version instead but even iterating create house manually appending one initiallyempty list lowlevel python knows construct list values need tell and bonus typically get better performance letting part since actual looping logic done internally native c we instead describe want list list comprehension we walk steps take windowcount turn make corresponding house add list say list houses corresponding windowcount windowcount input list directly that arguably clunkier english much cleaner programming language like python skip bunch little words expend effort describe initial list act appending finished houses list you describe process result madetoorder finally general programming concept makes sense whenever possible delay construction object everything

it confusing first code really need virtual environment directory actually better put code inside environment might want use different environments code example test code different versions python different versions library virtualenvwrapper put environments single place virtualenvwrapper convenient tool top virtualenv need put code environments different places maybe get bit comfortable virtualenv starting use virtualenvwrapper you let paster create directory project name this directory commit version control eg git mercurial you want commit directory containing virtual environment,i new pyramid paster reading docs i use virtualenv inside virtualenv dir i want start pyramid project the problem i would like paster create dir project name instead put scaffold files current dir venv root i thought using paster i still know point app developmentini use option i could also virtualenv entirely different place filesystem seems weird maybe virtualenvwrapper could make easier any way,2

pep extensive discussion might wanna take look,in python functions created using def lambda dict attribute dynamically add attributes having dict every function memory cost an empty dict uses bytes cpython adding attributes function particularly common thing use custom object call method cases need function nonstandard attributes since adding custom attributes function common use case dict memory cost python functions dict,3

in python functions created using def lambda dict attribute dynamically add attributes well yes objects having dict every function memory cost an empty dict uses bytes cpython it bytes not really matters sake discussion if really needed save every byte using python in program uses lot memory functions normally represent tiny fraction number objects overhead really important imo much worried fact costing bytes per floatingpoint value switch double float of course way worry use numpy adding attributes function particularly common thing if come javacc world i imagine must seem horribly messy but people come perljavascript world even rather different direction maybe something like scheme haskell pretty elegant so basically i would say answer,in python functions created using def lambda dict attribute dynamically add attributes having dict every function memory cost an empty dict uses bytes cpython adding attributes function particularly common thing use custom object call method cases need function nonstandard attributes since adding custom attributes function common use case dict memory cost python functions dict,2
keys must unique using keys means two values associated when creating dictionary setting key correspond value so first abc kfc but continually overriding keys give different values in end latest values keys kept type tag,thevalues u abc u kfc u listproperty u models u new u newer u note u order u tag u test u type thekeys dictzipthekeys thevalues u type u tag can give clue type tag taken i trying sort thevalues thekeys i noticed switching order thevalues thekeys works dictzipthevalues thekeys u abc u models u note u tag u kfc u newer u listproperty u test u new u type u order thanks,2

i see two separate problems keeping track python modules need project keeping track dynamic libraries need python modules project for first problem i found buildout good help althought takes litle grasp in case i would start creating directory new project i would go directory download bootstrappy wget httppythondistributeorgbootstrappy i would create buildoutcfg file buildout parts qrproject python eggs pyqrencode qrproject recipe zcrecipescripts eggs buildouteggs entrypoints qrprojectqrprojectmodulerun extrapaths buildoutdirectory this simple way creating interpreter access eggs modules project uses python recipe zcrecipescripts interpreter python eggs buildouteggs extrapaths buildoutdirectory in buildoutcfg i referencing module qrprojectmodule entrypoints qrproject this create binqrproject runs function run module qrprojectmodule so i also create file qrprojectmodulepy import qrencode def run print entry point qrproject happily imports qrencode module now time run bootstrappy python binary want use python bootstrappy then run generated binbuildout binbuildout this create two additional binaries bin directory binqrproject binpython the former project main binary it created automatically time run buildout modules eggs want loaded the second simply convenient way get python prompt modules eggs loaded easy debugging the fine thing binbuildout automatically install python eggs eggs case pyqrencode specified dependencies actually probably get compilation error step run binbuildout this need address problem all dynamic libraries available system on linux usually best get help packaging system i going assume using debian derivate ubuntu the pyqrencode web site specifies need libqrencode library pyqrencode work so i used package manager search aptcache search libqrencode libqrencodedev qr code encoding library development libqrencode qr code encoding library qrencode qr code encoder png image in case i want dev package installs linkable libraries header files required compile python cmodules also dependency system package manager make sure i install libqrencodedev i also get libqrencode required runtime ie compilation module so i install package sudo aptget install libqrencodedev once completed rerun binbuildout pyqrencode module hopefully compile install successfully now try run binqrproject binqrproject entry point qrproject happily imports qrencode module success so summary use buildout automatically download install python moduleseggs need project use system package manager install dynamic c libraries required python modules use be aware many cases already packaged versions python modules available package system for example pil available installing pythonimaging package ubuntu in case need install via buildout need worry

cpython classic prevalent implementation python one thread executing python bytecode time this means computebound programs use one core io operations computing happening inside c extensions numpy operate simultaneously other implementation python jython pypy may behave differently i less clear details the usual recommendation use many processes rather many threads,question because python use gil python capable running separate threads simultaneously info after reading i came away rather uncertain whether python capable taking advantage multicore processor as well done python feels really weird think would lack powerful ability so feeling uncertain i decided ask if i write program multi threaded capable executing simultaneously multiple cores,3
the answer yes but but cpython cannot using regular threads concurrency you either use something like multiprocessing celery mpipy split parallel work another process or use something like jython ironpython use alternative interpreter gil a softer solution use libraries run afoul gil heavy cpu tasks instance numpy heavy lifting retaining gil python threads proceed you also use ctypes library way if cpu bound work ignore gil issue entirely kind since python aquire gil waiting io,question because python use gil python capable running separate threads simultaneously info after reading i came away rather uncertain whether python capable taking advantage multicore processor as well done python feels really weird think would lack powerful ability so feeling uncertain i decided ask if i write program multi threaded capable executing simultaneously multiple cores,3
python threads cannot take advantage many cores this due internal implementation detail called gil global interpreter lock c implementation python cpython almost certainly use the workaround multiprocessing module httpwwwpythonorgdevpepspep developed purpose documentation httpdocspythonorglibrarymultiprocessinghtml or use parallel language,question because python use gil python capable running separate threads simultaneously info after reading i came away rather uncertain whether python capable taking advantage multicore processor as well done python feels really weird think would lack powerful ability so feeling uncertain i decided ask if i write program multi threaded capable executing simultaneously multiple cores,3

rule rest objects not methods the rest resources become fragmented false always false rest resources independent they fragmented instead device resource i resources device devicestatus driver

consider providing status device information together single composite document describes device just relational database normalized mean restful objects need precisely normalized database while

the reason pass python indentation dependent expects one indented statement colon class function when statements case stubbed function class still needs least one indented statement use special pass statement placeholder you could easily put something effect like class loaf true also fine less clear using pass opinion,can explain concept stubbing functions classes taken article class loaf pass this class define methods attributes syntactically needs something definition use pass this python reserved word means “move along nothing see here” it statement nothing good placeholder stubbing functions classes thank,1
stubbing technique software development after planned module class example drawing uml diagram begin implementing as may implement lot methods classes begin stubs this simply means write definition function leave actual code later the advantage forget methods continue think design seeing code,can explain concept stubbing functions classes taken article class loaf pass this class define methods attributes syntactically needs something definition use pass this python reserved word means “move along nothing see here” it statement nothing good placeholder stubbing functions classes thank,1
stubbing functions classes this refers writing classes functions yet implementing for example maybe i create class class fooobject def barself pass def tankself pass i stubbed functions i yet implemented however i think great plan instead class fooobject def barself raise notimplementederror def tankself raise notimplementederror that way accidentally call method implemented get error nothing happening,can explain concept stubbing functions classes taken article class loaf pass this class define methods attributes syntactically needs something definition use pass this python reserved word means “move along nothing see here” it statement nothing good placeholder stubbing functions classes thank,3
a stub placeholder class function anything yet needs class function question defined the idea already use certain aspects put collection pass callback even though written implementation yet stubbing useful technique number scenarios including team development often lead programmer provide class skeletons filled method stubs comment describing method leaving actual implementation team members iterative development stubbing allows starting partial implementations code complete yet still compiles details filled course later iterations demonstrational purposes if content method class interesting purpose demonstration often left leaving stubs,can explain concept stubbing functions classes taken article class loaf pass this class define methods attributes syntactically needs something definition use pass this python reserved word means “move along nothing see here” it statement nothing good placeholder stubbing functions classes thank,2

your question somewhat incomplete comparing two different operations if need add two things together testing xy going get anywhere so presumably want compare sum sum it lot complex interpreted languages like python hardware test nonzero introduces branch expensive but i want say would faster without timing throw equation different performance characteristics different architectures another confounding factor as always best write code natural maintainable way first time if feel need extract performance use profiler find hot spots optimise,which cpu intensive ifxnum check sum xy,1

yes function called map def yx return x mapy the map function applies function every item returns list results,is way i give python list values like obtain function relates values like x something like i want plot anything i want substitute values function see result would edit way python calculate data related like i give list containing thousands values returns function adjusted values,1
based comments david heffernan answer i want know relation values i thousands values stored list i want know python tell related seems like trying regression analysis probably linear regression fit values you use numpy linear regression analysis python here sample numpy cookbook,is way i give python list values like obtain function relates values like x something like i want plot anything i want substitute values function see result would edit way python calculate data related like i give list containing thousands values returns function adjusted values,2

based revised question i going go ahead add answer no function i imagine unlikely find function comes close programming language your definitions tight enough anything reasonable yet if take simple case two input integers sorts relationships possible relationships def xy return def xy return def xy return repeat admittedly arbitrary valid relationships first second values array passed the possibilities solutions become even absurd ask relationship numbers,is way i give python list values like obtain function relates values like x something like i want plot anything i want substitute values function see result would edit way python calculate data related like i give list containing thousands values returns function adjusted values,1

i would suggest keeping simple create database table store events insert table appropriate implement simple ajax polling technique hit server every x seconds client side i concerns solutions considering using pushnotification approach using nosql data store it whole lot complicated traditional pullnotification system using tools built django framework except rare exceptions overkill unless specifically require strict realtime solution keep simple use tools already exist framework people objections based database network performance i say premature optimization root evil build model contains recent activity data specific application whenever application something log new activity insert table your view would simply like view pulling top x rows recentactivity table optionally based query parameters whatever then client side simple ajax poller hitting view every x seconds there shortage complicated plugins technologies use writing complicated either function simplepoll getyoururl queryparameters functiondata stuff data replacing div updating json whatever settimeoutsimplepoll delay my opinion performance issues really issues site successful enough issue a traditional relational database scale fairly well start reaching level success like twitter google etc most us level,i need develop realtime recent activity feed django ajax longpolling i wondering best strategy serverside pseudocode def recentactivitypostsave notifyview view newactivity sleep return httpresponsenewactivity the first thing comes mind querying db every second not feasible other options using cache notification service using specialized tool like celery i rather seems like overkill what best way go,3

a regular expression able achieve i give examples variable could come strict expression to match something like following import match etc timex recompile dd pm nst match timexmatchtext remres variable matchgroups edit code actually work unlike first attempt import match etc timex recompile dd pm nst match timexsearchtext match variable matchgroups,i currently code goes url fetches source code i trying get return variable string so i created changetime refreshsourcefind variable pm nst but find area string word variable something else how would i retrieve constantly changing variable string,1
you setting cc cxx environment suitable wrapper around compiler example colorgcc,i currently using colorama package color messages generated build scripts i also used scolorizer replaces build commands custom colored messages using strfunction scons this sure makes build output less verbose warnings easier spot however i often prefer see full command lines building is mechanism scons capture compiler output giving opportunity inject terminal colors printing,1
if pattern really simple seems typical case regular expressions comes quite handy note new regular expressions may want use introduction like httpwwwregularexpressionsinfo on hand pattern complex may want use html parser like instance beautifulsoup,i currently code goes url fetches source code i trying get return variable string so i created changetime refreshsourcefind variable pm nst but find area string word variable something else how would i retrieve constantly changing variable string,1

short answer not usually long answer it take time load module this may noticeable loading python network drive slow source but running directly hard drive never notice as wrar points importing module execute amount code you whatever code want executed module startup however modules avoid executing unreasonable amounts code startup so probably huge cause however importing large modules especially also result importing large number c modules take time so importing take time per module imported if import modules top modules opposed functions applies startup time anyways basically going get much optimisation mileage avoiding importing modules,i running website using django i import ipdb beginning almost scripts make debugging easier however time i never use functions module i debugging just wondering decrease performance it i want create breakpoint i prefer write ipdbsettrace opposed import ipdb ipdbsettrace but i seen second example done several places makes wonder efficient i know importing python modules relates efficiency assuming using module methods within script,1

len tell length list to quote docs lens nbspnbspnbspnbspreturn length number items object the argument may sequence nbspnbspnbspnbspstring tuple list mapping dictionary of course want get final element list tuple string since indexes based length item element count alena last item as aside generally proper way access last element object allows numeric indexing str list tuple etc using obviously involve len though,list say i want see null way without using exception assertion,3
you providing specific usecase generally list would use len see many elements list lena do something,list say i want see null way without using exception assertion,1
use len lena index note your question asks would find null anything get indexerror try check,list say i want see null way without using exception assertion,1
the general way check currently looking element end list language compare current index looking length list minus one since indexes start really anything exist languages may implement null undefined many simply throw exception try access instead,list say i want see null way without using exception assertion,1

don use string concatenation loop use strjoin instead cpython implementation detail if strings python implementations cpython usually perform inplace optimization assignments form when applicable optimization makes quadratic runtime much less likely this optimization version implementation dependent for performance sensitive code preferable use strjoin method assures consistent linear concatenation performance across versions implementations your code would look like buf joinstrrandomrandint j range and note since specified separator look like change want numbers example comma separated i also think need buffer writing file already buffered,i trying tests external sorting algorithms i thought i generate huge amount random numbers put file here i import tempfile random nf tempfilenamedtemporaryfiledeletefalse j buf j buf strrandomrandint j nfwritebuf i thought i speed generating process reducing file io operations i use buf store many numbers possible write buf file question i still got sense generating writing process slow am i getting something wrong edit in c simply write int float file without converting string so python i mean write integer file without converting str,2

i suspect following happens ab python looks value finds kind reference b says true ab python looks finds b looks since holds b b now sees b holds kind reference exactly b so python compare elements means compare b now infinite recursion starts note works python actually copy list assigning ab python rather creates reference b stored,it possible create infinite nested list python that clear although popular definitely useful known fact true my question happening b b b b b traceback recent call last file stdin line module runtimeerror maximum recursion depth exceeded cmp b true b traceback recent call last file stdin line module runtimeerror maximum recursion depth exceeded cmp b true which way deeper i trying understand i feel much like brain going explode i see contains b contains now questions one do really two lists one how thing like gets stored memory what could purpose enable programers implement something strange like please treat question superserious and forget programming fun sometimes,3

using threading going problem you also going achieve parallelism the global interpreter lock gil python allows single thread process time if want true parallel processing need look multiprocessing module it ability actually leverage multiple processors machine,i function myfunc eg takes start end date amp iterates accesses dictionaries process data time period i looking use threads parallelize code my main function reads data bunch files amp stores dictionaries every time i call myfunc i pass dictionaries start amp end date when i call myfunc using multiple threads pass along dictionaries would conflict these dictionaries used readonly purposes myfunc creates lot dictionaries writes another file this output file would differ every thread since across threads dictionaries named would conflict theoretically i understand concept threading means conflict long dictionaries global but since first attempt threading would like confirmation thanks,3

python sets implementation operator you use set union amp set intersection sets implement set difference you also use symmetric set difference ie return new set objects appear one set appear sets,i would like know valid setrange setrange valid setrange setrange is could mean intersection union,3
because means union amp means intersection there clearly reason add multiple operators function the reasons using amp probably goes back bitwise operations if represent set bits number operators use union intersect simple tied union set difference,i would like know valid setrange setrange valid setrange setrange is could mean intersection union,3
sure could used union would still need symbol intersection union symmetrical amp intersection thus makes better choice,i would like know valid setrange setrange valid setrange setrange is could mean intersection union,3
because set difference useful commonly known concept universally used concept „set addition“,i would like know valid setrange setrange valid setrange setrange is could mean intersection union,1

python chose use instead set union concept closely related boolean disjunction bit vectors python int long define operation across sequence boolean values call bitwise in fact operation similar set union binary integers sometimes also called bit sets elements set taken natural numbers because int already defines setlike operators amp natural newer set type use interface,i would like know valid setrange setrange valid setrange setrange is could mean intersection union,3

in set theory symbol normally indicates disjoint union two sets if a b sets disjoint union defined set a b a u b b b ie construct disjoint union mark elements a elements b different tags example i used numbers two different things would job take union two resulting sets in example i used u set union make similar usual mathematical notation i use python notation ie union amp intersection if a b disjoint a b correspondence a b if common elements x a amp b appear twice a b x x so since symbol quite wellestablished meaning set operation i find consistent python use symbol set union intersection probably python designers mind chose set operators,i would like know valid setrange setrange valid setrange setrange is could mean intersection union,3

nonnegativevalues linear diphantine equations a question i asked ago the accepted answer great way enumarte combos step,i learning programming python algo’s trying work project i find interesting i created basic python scripts i’m sure approach solution game i trying build here’s game work users given items value for example apple pears oranges they get chance choose combo like ie apples pears oranges the output computer gets total valuein example currently the computer try guess which obviously won’t able get correctly first turn value quantityday valueday apple pears orange total the next

done far here’s solution farnot much basically i take values figure possible combos themi done part then i take possible combos put database dictionaryso example could dictionary entry apple pears

two days data removes possibilities variance previous days data questions so question user changing total list probabilities i approach what i need learn is algorithms theories i use applicable or help understand mistake suggest rules i add make goal feasibleif current state i thinking adding fruits saying must pick least etc also i vague understanding genetic algorithms i thought i could use something i use i eager learn advice tips would greatly appreciatedjust please tell game impossible thanks advance update getting feedback hard solve so i thought i add another condition game interfere player doinggame stays everyday value fruits change pricerandomly would make easier solve because within movement certain fruit value changes combo probable time day anything possible getting close enough range almost impossible prices fruits change user choose change tover time range narrow narrow in example prices volatile enough i think i could brute force solution gave range

what want recursive type different languages different ways for example ocaml staticallytyped language optional compilerinterpreter flag rectypes enables support recursive types allowing define stuff like let rec printendline b b printendline b c c printendline c although ugly complained c example happens underneath still the compiler simply worries instead forcing write as others pointed haskell use newtype overhead but complain explicitly wrap unwrap recursive type ugly similarly c example overhead since machine level member struct identical member ugly another example i want mention go another staticallytyped language in go type construct defines new type it simple alias like typedef c type haskell creates fullfledged new type like newtype haskell type independent method set methods define because type definition recursive type fn func fn,i implemented simple state machine python import time def print return b def b print b return c def c print c return name main state true state state timesleep i wanted port c fast enough but c let make function returns function type i tried making function type typedef fnfn work i use structure instead now code ugly include stdioh include stdlibh include unistdh typedef struct fn struct fn fvoid fnt fnt avoid fnt bvoid fnt cvoid fnt avoid fnt f b voidprintfan return f fnt bvoid fnt f c voidprintfbn return f fnt cvoid fnt f voidprintfcn return f int mainvoid fnt state voidsleep state statef return exitsuccess so i figured problem c broken type system so i used language real type system haskell problem happens i something like type fn io fn fn print return b b fn b print b return c c fn c print c return i get error cycle type synonym declarations so i make wrapper way i c code like import controlmonad import systemposix data fn fn io fn io fn print return fn b b io fn b print b return fn c c io fn c print c return fn run foldm fn f sleep f fn repeat why hard make state machine statically typed language i make unnecessary overhead statically typed languages well dynamically typed languages problem is easier way statically typed language,2

the kademlia paper actually calls optimization dynamically splitting buckets routing table grows there logic difference two approaches optimization save space when implementing fixed full sized routing table find k nodes send requests if bucket target falls empty fewer k nodes pick neighboring buckets given closest bucket split first place makes search simpler faster point i think may misunderstood kademlia the routing table bucket boundaries always relative node id and id space buckets span double bucket away without property say bucket covered equal range id space would able searches properly would certainly logn the mainline dht implements kademlia,i middle implementing dht internal cluster since used filesharing program like bittorrent mainline dht first thing i look after i found entangled python dht using twisted matrix congress python dht using pyev libev course original kademlia they different approaches organizing kbuckets congress kademlia use fixed buckets range difference id us mainline dht entangled use dynamic buckets on start bucket covering whole space after filled alive nodes bucket splitted new but only id inside bucket if bucket never splitted so soon closest us buckets both variants good enough but i found huge difference logic detects belongs id bucket and question congress kademlia treat bucket bundaries minimum distance us maximum distance us so id always bucket maximum ids bucket covers x distances always closest us so brain breaks coz everything ok but look mainline dht entangled see bucket bundaries treated absolute node id bundaries xor distance so theoretically full table ids bucket so why implementations treat bucket boundaries maxmin distance us others maxmin bit integer value,3

i think third example best solution it shortest version it avoids duplication it clear read easy follow much unlike second version you might want use newer except fooerror err syntax though python higher also example first version quite correct since urlerror handler already catches httperror except httperror part never reached you switch two except around another reason use,what good pattern avoid code duplication dealing different exception types python eg i want treat urlerror httperror simlar quite try page urlopenrequest except urlerror err loggererroran error ocurred err except httperror err loggererroran error occured err loggererrorerror message errread in example i would like avoid duplication first loggererror call given urlerror parent httperror one could something like except urlerror err loggererroran error occurred err try raise err except httperror err specialization http errors loggererrorerror message errread except pass another approach would use isinstance eg urlerror httperror would chain inheritance except urlerror httperror err loggererroran error occured err isinstanceerr httperror loggererrorerror message errread which one i prefer another better approach,3

two approaches ex commands formatting my first thought textwidth se tw gnorm gqq ampg this sets text width chars reformats nonempty line inserts space start lines start use macro alternatively make macro gg qqfacrescjq q rationale go begin buffer record macro q qq starts recording q ends recording f forward second comma acresc append newline j next line move caret first character rinse repeat number times repeat processing stop macro fails eg end file,so i several large datasets i need make readable currently i go move rd value insert newline i tried several things vim get work none seem return value i looking here data what i need make look like instead i used selection try get move rd value duplicated entire thing moved entire line ssrampg i also tried removing make work work either so way i capture rd value insert carriage return newline make work thanks edit i apologize miscommunicating part problem the data top one line several lines it looks like e,3

disclaimer i changed answer dramatically temporarily deleting answer rereading question carefully i misread critical parts question while still referencing similar topics algorithms answer greatly improved i attempted solve problem c hollywood version the problem dynamic constraint satisfaction problem dcsp variation constraint satisfaction problems csp use monte carlo find potential solutions given day values quantity ranges tiny otherwise use brute force find every potential solutions use constraint recording related dcsp applied cascade previous days restrict potential solution set cross fingers aim shoot guess based probability optional bruce willis wins original version first i would like state i see two main problems the sheer number possible solutions knowing number items total value lets say example yield lot possible solutions plus easy algorithm picking valid solution without inevitably trying invalid solutions total equal when possible solutions found given day d one must find way eliminate potential solutions added information given d d let lay bases upcoming examples lets keep item values whole game it either random chosen user the possible item values bound limited range two items value no item quantity greater that means in order solve easily i took liberty change one constraint makes algorithm converge faster the total quantity rule overridden rule you add remove number items within range total one day however cannot add remove number items total twice this also gives game maximum lifecycle days this rule enables us rule solutions easily and nontiny ranges renders backtracking algorithms still useless like original problem rules in humble opinion rule essence game facilitator enabling computer solve problem problem finding potential solutions for starters problem solved using monte carlo algorithm find set potential solutions the technique simple generate random numbers item values quantities within respective accepted range repeat process required number items verify whether solution acceptable that means verifying items distinct values total equal target total say while technique advantage easy implement drawbacks the user solution guaranteed appear results there lot misses for instance takes less tries find potential solutions given constraints it takes lot time around seconds lazy laptop how get around drawback well limit range smaller values find adequate number potential solutions good chance user solution appears solution set use heuristics find solutions easily later note restrict ranges less useful monte carlo algorithm since enough valid solutions iterate reasonable time for constraints around valid solutions constrained target total value monte carlo usable for around no need use monte carlo brute force loops fine i believe problem would call constraint satisfaction problem csp problem restrict set potential solutions given fact problem csp i would go ahead call problem problem general dynamic csp dcsp dcsps useful original formulation problem altered way typically set constraints consider evolves environment dcsps viewed sequence static csps one transformation previous one variables constraints added restriction removed relaxation one technique used csps might useful problem called constraint recording with change environment user entered values d find information new constraint what possibly used quantities addremove constraint apply constraint every preceding day cascade rippling effects might significantly reduce possible solutions for work need get new set possible solutions every day use either brute force monte carlo then compare solutions d d keep solutions succeed previous days solutions without violating constraints you probably keep history solutions lead solutions probably directed graph constraint recording enables remember possible addremove quantities rejects solutions based there lot steps could taken improve solution here ideas record constraints itemvalue combinations found previous days solutions reject solutions immediately item values must change you could even find smaller solution sets existing solution using solutionspecific constraints reject invalid solutions earlier generate mutant fullhistory solutions day order repair case d solution set contain user solution you could use genetic algorithm find mutant population based existing solution set use heuristics order find solutions easily eg valid solution found try find variations solution substituting quantities around use behavioral heuristics order predict user actions eg quantity every item extreme patterns etc keep making computations user entering new quantities given try figure ranking system based occurrence solutions heuristics determine candidate solution,i learning programming python algo’s trying work project i find interesting i created basic python scripts i’m sure approach solution game i trying build here’s game work users given items value for example apple pears oranges they get chance choose combo like ie apples pears oranges the output computer gets total valuein example currently the computer try guess which obviously won’t able get correctly first turn value quantityday valueday apple pears orange total the next turn user modify numbers total quantity percent may chose i’ll use example the prices fruit changeat random total value may change based alsofor simplicity i changing fruit prices example using example day game user returns value day here example quantityday changeday valueday quantityday changeday valueday i hope tables show right i manually space hopefully screen work let know i try upload screenshot i trying see i figure quantities timeassuming user patience keep entering numbers i know right restriction total value cannot i cannot within accuracy right user entering forever what i done far here’s solution farnot much basically i take values figure possible combos themi done part then i take possible combos put database dictionaryso example could dictionary entry apple pears oranges way apple pears oranges i time i get new number i list possibilities here’s i’m stuck is using rules i figure best possible solution i think i’ll need fitness function automatically compares two days data removes possibilities variance previous days data questions so question user changing total list probabilities i approach what i need learn is algorithms theories i use applicable or help understand mistake suggest rules i add make goal feasibleif current state i thinking adding fruits saying must pick least etc also i vague understanding genetic algorithms i thought i could use something i use i eager learn advice tips would greatly appreciatedjust please tell game impossible thanks advance update getting feedback hard solve so i thought i add another condition game interfere player doinggame stays everyday value fruits change pricerandomly would make easier solve because within movement certain fruit value changes combo probable time day anything possible getting close enough range almost impossible prices fruits change user choose change tover time range narrow narrow in example prices volatile enough i think i could brute force solution gave range guess i trying figure elegant solution solutions keep narrowing range time update after reading asking around i believe hidden markovviterbi problem tracks changes fruit prices well total sumweighting last data point heaviest i sure apply relationship though i think case could wrong least i starting suspect type

since taking user input safest way define exactly valid input dispatcher add add w add try functiondispatcherw except keyerror raise valueerror invalid input if want evaluate strings like add could use safe eval eval add builtins nonedispatcher eval general could dangerous applied user input the safer since builtins disabled locals restricted dispatcher someone cleverer i might able still cause trouble i tell warning even eval builtins none dispatcher unsafe applied user input a malicious user could run arbitrary functions machine given opportunity string evaluated eval,for example i function called add like def addxy return xy i want ability convert string input direct function like wrawinput please input function want use w add is way use w refer function add,3
the builtin function eval want all usual warnings executing arbitrary usersupplied code apply if finite number predefined functions avoid eval use lookup table instead ie dict never trust users,for example i function called add like def addxy return xy i want ability convert string input direct function like wrawinput please input function want use w add is way use w refer function add,3
one safe way map names functions it safer using eval functionmappings add add def selectfunction true try return functionmappingsrawinput please input function want use except keyerror print invalid function try,for example i function called add like def addxy return xy i want ability convert string input direct function like wrawinput please input function want use w add is way use w refer function add,3
unutbu solution i would normally use completeness sake if specifying exact name function use eval although highly discouraged people malicious things evaladdxy,for example i function called add like def addxy return xy i want ability convert string input direct function like wrawinput please input function want use w add is way use w refer function add,3

the best solution depends releasing license releasing if concerned revealing code apps distributing service like github bitbucket way go the best way contribute code community releasing open source version control allows people contribute learn but depending audience might need something userfriendly in case cxfreeze pyinstaller perfectly acceptable solutions if distributing package may want look setuptools,quick question once i build py app wx gui etc i compile pyinstaller cxfreeze send binaries servers correct is good way distribute script i fairly new app development cycle i python script i would like make public make life easier if share code rest community provide people py code wanted distribute binaries well would compile py pyinstaller cxfreeze would use method dev environment currently mac osx debian domu thanks,2

we working updating neojdjango integration work neojrestclient fruits labor github quick comments blog there pros cons integration the obviously impacting use rest client get use remote database losing quite bit performancewise otoh integration works alongside relational database still use djangocontrib stuff relies original orm handles indexing query sets pretty nicely to want using neodjango simply get neojrestclient based node model instance modelinstancenode newproperty something we still cranking making integration dynamic supporting traversalsetc pythonic way currently important improving performance if interested i love feedback,so i looking django neoj integration much what i want know i model like one if i want add new property model would simple nodesetproperty newproperty something moreover queries django would work how traversing made i would appreciate response d thanks,3
we updated old django integration use neojrestclient called neodjango we made major improvements old integration using successfully build scholrly it quite production something the library allows model definition query sets automated indexing works alongside relational database still use contrib modules based standard orm i posted bit elsewhere stackoverflow interested,i planning implement recommendation engine details given python preferred choice along neoj database can anyone please point integration neoj web framework like django done is possible integrate like php integrates mysql thanks advance,2

able get correctly first turn value quantityday valueday apple pears orange total the next turn user modify numbers total quantity percent may chose i’ll use example the prices fruit changeat random total value may change based alsofor simplicity i changing fruit prices example using example day game user returns value day here example quantityday changeday valueday quantityday changeday valueday i hope tables show right i manually space hopefully screen work let know i try upload screenshot i trying see i figure quantities timeassuming user patience keep entering numbers i know right

take possible combos put database dictionaryso example could dictionary entry apple pears oranges way apple pears oranges i time i get new number i list possibilities here’s i’m stuck is using rules i figure best possible solution i think i’ll need fitness function automatically compares two days data removes possibilities variance previous days data questions so question user changing total list probabilities i approach what i need learn is algorithms theories i use applicable or help understand mistake suggest rules i add make goal feasibleif current state i thinking adding fruits saying

that syntax stringstartendstep produces start last character this provide position slice would executed so go back characters last one reaches first one produces told python start nd character index string told python go back steps position which case python would obviously return this python tried go back steps already hit first character string one step you able figure one but i explain anyway so told python start third character index go back steps reaches first character so start go back steps accidentally first character happens reached so python give,so i really get deal stride parameter slicing for example produces produce produce,1

you writing file finally block exceptions raised caught except block the except bock executes exception raised try block the finally block always executes whatever happens also need initialising file variable none the use return except block skip finally block by nature cannot skipped want put cleanup code ie closing files so want use tryexceptfinally something like try f openfile w try fwrite hello world finally fclose except ioerror print oops a much cleaner way using statement try openoutput w outfile outfilewrite hello world except ioerror print oops,open new file write file none try file openfilepath w except ioerror msg unable create file disk fileclose return finally filewritehello world fileclose the code ripped function one user system reporting error line filewritehello world error attributeerror nonetype object attribute write question if python failed open given file except block executes return control getting transferred line throwing given error the value file variable none any pointers,3

if file opened line file openfilepath w fails nothing gets assigned file then except clause runs nothing file fileclose fails the finally clause always runs even exception and since file still none get another exception you want else clause instead finally things happen exception try file openfilepath w except ioerror msg unable create file disk return else filewritehello world fileclose why else the python docs say the use else clause better adding additional code try clause avoids accidentally catching exception wasn’t raised code protected try except statement in words catch ioerror write close calls which good reason woudn “unable create file disk” – would different error one code prepared it good idea try handle errors,open new file write file none try file openfilepath w except ioerror msg unable create file disk fileclose return finally filewritehello world fileclose the code ripped function one user system reporting error line filewritehello world error attributeerror nonetype object attribute write question if python failed open given file except block executes return control getting transferred line throwing given error the value file variable none any pointers,3

yes int instance takes bytes system integers like object attributes ie pointers objects take additional memory space beyond used object value so bytes integer value bytes pointer class otherwise python know type object belonged start resolving attribute names inherited int class parents another object reference count used garbage collector the type int occupies bytes system pointers various methods attributes int class whatever housekeeping information python requires class the int class written c standard python implementation could go look source code see,sysgetsizeofint mean int occupies bytes sysgetsizeof bytes int object memory requirement i thought int python represented bytes reporting bytes please someone explain reporting bytes int uses bytes,3
from documentation sysgetsizeof getsizeof calls object’s sizeof method adds additional garbage collector overhead object managed garbage collector that might sysgetsizeof giving bytes as first line keep mind int object int type int int integer type integer an integer python actually takes many bytes needs need worry overflow type functionality handled i believe distinction valid builtin types userdefined objects type probably similar size instance type,sysgetsizeofint mean int occupies bytes sysgetsizeof bytes int object memory requirement i thought int python represented bytes reporting bytes please someone explain reporting bytes int uses bytes,1

i know exactly floatinf gives float infinity greater number,in python want give set elements associated value use value comparisons i would want value infinite no matter number enter program number greater representation infinity,3
in python test floatinf in python import math test mathinf and test test test x will always true unless course pointed x also infinity nan number additionally python x only comparison ellipsis floatinf lesser eg float inf ellipsis would return true,in python want give set elements associated value use value comparisons i would want value infinite no matter number enter program number greater representation infinity,3

to explain actually happens you try resize image negative width pil tries allocate negatively sized image fit resized image pil calls malloc negative amount memory hold negatively sized image malloc takes sizet unsigned as result negative memory request gets interpreted large number rather negative number malloc cannot allocate something large produces error to pil looks exactly like memory error reports so invalid inputs causing leaks bad behavior they result bad malloc request give pil could check negative sizes thus produce better error message perhaps figure worth already produces error message as happens actually running memory hard os try pretty hard keep process going using virtual memory your system bog gets point running memory so i found outofmemory errors caused requests negative amounts memory as far i recall real outofmemory errors i gotten java probably due use virtual machine,i using pil python image library image manipulation specifically i stitching images together my code seems work fine images small quantities sometime i getting memoryerror the part particularly strange i manipulations bit images work images kb i making lot calls imageresize i surprised significant issues here stack track traceback recent call last file testpy line module pprintscalematrixdown inpt file usersjeremykarmeldesktoppythonmergerpy line scalematrixdown return shrinkrowrow rowwidthoverflowrow row matrix file usersjeremykarmeldesktoppythonmergerpy line shrinkrow rest shrinkimim pixelsperim im rowremainingpixels file usersjeremykarmeldesktoppythonmergerpy line shrinkim return imresizeimsize numpix imsize numpix file librarypythonsitepackagespilimagepy line resize im selfimresizesize resample memoryerror keep mind images less x pixels i much dead end really sure proceed what i release memory should i calling del operator something simpler i thanks advance help,3

yeah basic idea autoloaded tables cannot declared without valid engine need separate initialization code model code ensure models imported setup engine connected metadata the link describes better looks like already taken correct approach sqlalchemy declarative syntax autoload reflection pylons,i pretty new pyramid i figure use autoloadtrue option pyramid i used pyramidroutesalchemy create project using paster the problem initpy file uses initializesql function defines basemetadatabind engine in one model classes i would like use autoloadtrue option using declarative base i always get following error sqlalchemyexcunboundexecutionerror no engine bound table metadata pass engine table via autoloadwithsomeengine associate metadata engine via metadatabindsomeengine actually basemetadatabind engine defined inside initializesql function i realy know order file loaded i almost sure initpy loaded model thus metadata already binded engine thus question use autoload within classes without changing whole init model structure if anyone hint thanks advance,1

the reason else dx syntax error python assignment statement but conditional operator expects expressions every expression statement every statement expression,i new python i trying write x dx q dx compact way using ternary operator q dx x else dx gives syntax error what i missing,2
the conditional operator python used expressions assignments statements you use q dsetdefaultx get desired effect case see also documentation dictsetdefualt,i new python i trying write x dx q dx compact way using ternary operator q dx x else dx gives syntax error what i missing,3
in python assignments cannot occur expressions therefore write code like b c you looking setdefault q dsetdefaultx alternative use defaultdict,i new python i trying write x dx q dx compact way using ternary operator q dx x else dx gives syntax error what i missing,2

one big disadvantage java tracing gc time time stop world freeze application relatively long time full gc if heap big object tree complex freeze seconds also full gc visits whole object tree something probably quite inefficient another drawback way java gc tell jvm heap size want default good enough jvm derives value several thresholds trigger gc process much garbage stacking heap i presume actually main cause jerky feeling android based java even expensive cellphones comparison smoothness ios based objectivec using rc i love see jvm option enable rc memory management maybe keeping gc run last resort memory left,python uses reference count method handle object life time so object use immediately destroyed but java gcgarbage collector destroys objects longer used specific time why java choose strategy benefit is better python approach,1

you problem solved several ways i think consider using regular expression perl example directly python regular expressions module an example would import filecontent open somefiletxt read print refindall dd filecontent i would prefer using instead n line endings line endings different operational systems file encodings if want call bash commands inside python could use import os ossystemmycommand where command bash command i use time operations better perform bash python finally want extract numbers grep use option prints matched part,i need pick numbers text files i pick lines i need grep know extract numbers lines a colleague showed bash perl cat resultstxt perl pe sddn however i usually code python perl so question could i used python way ie could i piped something bash python gotten result straight stdout makes sense or perl convenient case,1

both ways equivalent although homework task seems require create d array first reshape d afterwards v nprandomrandint num numpy allocates single memory block num integers fills random values drawn uniformly interval returns array interprets d array ccontiguous d array num rows columns v nprandomrandint num z npreshapev num this thing explicitly v still d array z view v interpreting data d array this means changing value v also change z since arrays point memory z npreshapev num the make sense array dimensions cannot negative numpy support one dimension take special value means infer dimension automatically size array it seems also accepts negative numbers purpose undocumented feature that means might well bug removed future versions either reshape explicitly num use num let numpy autodiscover please also note assignment says four rows n columns whereas arrays num rows columns for example d array reshaped,the homework task sounds something like generate random vector n uniform integer numbers ranging reshape vector array four rows n columns representing outcome n throws four dice i come following solution import numpy np num v nprandomrandintnum so far good i noticed generated array x n shape point creation reshaped i considered following well v nprandomrandintnum z npreshapevnum is difference two terms v built from couple print statements seem terms shape i could make sense documentation,1

instance return pass better worse pass would continue execution method a return would terminate execution method regarding following lines want put return else return pass better worse make difference even removing whole two lines change anything but anyway imagine would elaborate method it better choose right flow beginning,i seen code pinax django apps instead pass empty return statement used what difference would effect example django code i running the code signal method automatically saves hashtags taggit tag objects tweet object i saw question whether return statement php makes difference interpreted bytecode i sure relevant python import tagregex recompiler ptagw def gettaggedsender instance kwargs automatically add tags tweet object instance return pass better worse post instance tagslist smartunicodetlower listsettagregexfindallpostcontent tagslist posttagsaddtagslist postsave else return pass better worse postsaveconnectgettagged sendertweet,1

in one line someboolvalue num but don’t this style normally expected people prefer longer form clarity consistency someboolvalue num equally camel caps avoided so rather use someboolvalue note inline expression somevalue predicate without else part exist would return value predicate false however expressions must clearly defined return value cases this different usage say ruby perl,i following code num someboolvalue true i need set value num someboolvalue true nothing otherwise so code num someboolvalue else num is someway i could avoid else num part make look cleaner an equivalent someboolvalue num i tried replacing else pass like num someboolvalue else pass all i got syntax error nor i could omit else num part thanks,3
no i guess hoping something like num someboolvalue would work i think best way statement written someboolvalue num,i following code num someboolvalue true i need set value num someboolvalue true nothing otherwise so code num someboolvalue else num is someway i could avoid else num part make look cleaner an equivalent someboolvalue num i tried replacing else pass like num someboolvalue else pass all i got syntax error nor i could omit else num part thanks,2
this comment answer fit comment instance return pass better worse as explained accepted answer pass would incorrect else return pass better worse here since end function pass would thing nothing even better would leave else clause entirely since nothing it true explicit better implicit zen rarely applies explicitly nothing clear happens else case anyone actually even wonders first place it also clear rename instance post within function could change parameter name sender argument supposed oh actually need convert set list iterate list comprehension,i seen code pinax django apps instead pass empty return statement used what difference would effect example django code i running the code signal method automatically saves hashtags taggit tag objects tweet object i saw question whether return statement php makes difference interpreted bytecode i sure relevant python import tagregex recompiler ptagw def gettaggedsender instance kwargs automatically add tags tweet object instance return pass better worse post instance tagslist smartunicodetlower listsettagregexfindallpostcontent tagslist posttagsaddtagslist postsave else return pass better worse postsaveconnectgettagged sendertweet,1

i think possible python since actually trying probably gets expanded something like num someboolvalue else num if exclude else num receive syntax error since i quite sure assignment must actually return something as others already mentioned could bad probably end confusing reading piece code next time someboolvalue num i big fan num someboolvalue num exact reason i actually think twice line the best way actually achieve want original version someboolvalue num the reason best verison obvious want confuse whoever else going come contact code later also side note num someboolvalue valid ruby code ruby works bit differently,i following code num someboolvalue true i need set value num someboolvalue true nothing otherwise so code num someboolvalue else num is someway i could avoid else num part make look cleaner an equivalent someboolvalue num i tried replacing else pass like num someboolvalue else pass all i got syntax error nor i could omit else num part thanks,3

yes use filter know position tuple desired column resides if case id first element tuple filter list like filterlambda mylist this return list corresponding tuples if want age pick element want instead filter could also use list comprehension pick element first go you could even unpack right away one result age mylist but i would strongly recommend use dictionaries named tuples purpose,i list tuples every tuple elements corresponding database columns i like make query select attribute mylist attribute something eg personage select age mylist personid is possible query list tuples way thank,2

this pythonspecific issue appears every language uses binary floating point pretty much every mainstream language from floatingpoint guide because internally computers use format binary floatingpoint cannot accurately represent number like when code compiled interpreted “” already rounded nearest number format results small rounding error even calculation happens some values exactly represented binary fraction output formatting routines often display shortest number closer actual value floatingpoint number masks rounding errors,i came across strange behavior python dictionaries the code i newitem val print newitem val print newitem and result val why it happens numbers others for example becomes becomes becomes becomes,3
this problem related floating point representations binary others pointed but i thought might want something would help solve implied problem python it unrelated dictionaries i i would remove tag if use fixedprecision decimal number purposes i would recommend check python decimal module from page emphaisis mine decimal “is based floatingpoint model designed people mind necessarily paramount guiding principle – computers must provide arithmetic works way arithmetic people learn school ” – excerpt decimal arithmetic specification decimal numbers represented exactly in contrast numbers like exact representations binary floating point end users typically would expect display binary floating point the exactness carries arithmetic in decimal floating point exactly equal zero in binary floating point result e while near zero differences prevent reliable equality testing differences accumulate for reason decimal preferred accounting applications strict equality invariants,i came across strange behavior python dictionaries the code i newitem val print newitem val print newitem and result val why it happens numbers others for example becomes becomes becomes becomes,1

my approach problem i wrap fortran code fpy explicitly declare relevant numpy arrays fortran order numpy happily work transparently even works well combining fortran c order arrays unfortunately seems numpy operations preserve fortran order therefore preallocate destination arrays passed mex fortran order example a npempty b npempty fill a b data want c npempty order f c npdota b note index essential c passed mex routine i sure much efficient solution a since assignment implicit copy however need reorder fortran arrays coming mex routine numpy deal quite transparently long knows order,i porting matlab code numpy this task includes stripping mex c code replacing equivalent calls numpy capi one problem mex code treats incoming data fortranordered matlab orders arrays numpy hand uses c ordering default short completely rewriting mex code c ordering i a reorder arrays go c code copy f reorder come copy c b figure get numpy emulate matlab everything fortran order getgo option a currently implemented works fine terribly inefficient anybody know make option b work,2

no difference i interested know documentation got impression the difference whether validation performed initial data trigger validation this allows example prefill certain fields leave others empty even though required if used bound data would get errors empty required fields even first viewing form would annoying user bound data course triggers validation also using modelform related instance updated bound data initial data,given example like class myformformsform name formscharfield i trying grasp difference following two snippets bound data style myform myform name requestuserfirstname initial data style myform myforminitial name requestuserfirstname the documentation seems suggest initial dynamic initial values yet able pass bound data constructor accomplishes exactly thing i used initial data past dynamic values i tempted use straightforward bound data style would like insights real difference two styles,3

if want add two classes i look add function allows normal addition call add b as question i exactly sure asking i wrote vector class like class vector def initself x z selfx x selfy selfz z def addself return vectorselfx otherx selfy othery selfz otherz,i guess would easy explain question examply suppose i want write vector class and class let say want define method add vectors something like class vector def addselfother code basically vector vec vecaddothervec addition like inherting classdatatype thanks,2
in python use duck typing ie worry type class vectorobject def initself x selfx x selfy def addself othervec return vectorselfx othervecx selfy othervecy if want make add modify vector object instead returning new one however makes class mutable therefore harder deal def addmutableself othervec selfx othervecx selfy othervecy,i guess would easy explain question examply suppose i want write vector class and class let say want define method add vectors something like class vector def addselfother code basically vector vec vecaddothervec addition like inherting classdatatype thanks,1

we want platform independent startup script invoking jvm system properties dynamically generated classpath you could use platform independent script generate platform specific startup script either installation time invocation in latter case additionally need simple static platform specific script invokes platform independent startupscriptgenerating script generated script in cases start application calling static platform specific script can invoke subprocess way stdout file written even parent process terminates you could open fileredirect child process eg using shell popen joinargs logfile amp shell specific cmdline shelltrue windows see cmdlinelist understand going,let start i really trying we want platform independent startup script invoking jvm system properties dynamically generated classpath we picked jython particular need depend standalone jythonjar startup script we decided could write jython script uses subprocesspopen launch application jvm terminates one thing our application uses lot legacy debug code prints standard so startup script typically redirecting stdoutstderr log file i attempted reproduce jython script like subprocesspopenargsstdoutlogfilestderrlogfile after line launcher script hosting jvm jython terminates the problem nothing shows logfile if i instead subprocesspopenargsstdoutlogfilestderrlogfilewait get logs so parent process needs run parallel application process launched via subprocess i want avoid two running jvms can invoke subprocess way stdout file written even parent process terminates is better way launch application jvm jython is jython bad solution anyway,1

i believe right wrong doubt reinventing wheel maybe different levels thinking gives hint how eat elephant level a software design at level would want stick best practice long operations done ui ui thread you need ui layer focuses gathering input including cancellation drawing including inprogressvisualization like progressbar hourglass this layer separated anything else dusk dawn any call outside layer must fast want intuitiveness responsiveness in tasks complex calls outside ui layer typically schecule work command queued smart layer pick whenever gets read results results queued smart layer could popped rendered cancelstopexit raise flag smart layer check flag don worry much user operations getting reaction slowly solid design core adjust priorities user input later or add shortterm hourglass similar or even cancel long operations get obsolete specific user input level b heavylifting smart layer there best framework kind hard work so i suggest design feeding ui layer simple possible frameworks involved internally implement using frameworks ability future redesign hardworking elements needed for example future could give math gpu share tasks serverfarms involve cloud computing for complex tasks picking framework top level design might prove obstacle future specifically may limit freedom applying technologies it hard tell sure seems silver bullet framework task so find strong tools eg threads queues implement good design practiceseg decoupling edit response edit your latest edit stresses perfectly hard challenges software designer meets for case

next level thinking might help here comes level d i stuck suggestion leave building walk cafe next corner order best coffee sit ask question what i need note different question what i want ping eliminated wrong answers start observing correct ones wrong answers i need framework would x y z i need screwdriver could run mph harvest forest farm nearby i need amazing internal structure user actually never see right answers forgive i understood problem wrong i need user able give input software i need user see calculations progress i need user visually see result calculations,im working piece software design im stuck idea im feeling like im reinventing wheel my situation following i designing scientific utility interactive ui user input trigger visual feedback duh directly ie editing domain geometry soon possible without blocking user interaction say solving pde said domain if i draw diagram operations i need perform i get rather awesomely dense graph exposing kinds opportunities paralellism cachingreuse partial results so i want primarily exploit paralellism transparant way selected subtasks executing seperate processes results outmatically joined downstream tasks waiting inputs ready plus needing recompute input branches actually input changed pyutilibworkflow seems come closest im looking except course isnt doesnt seem subprocessing begin that seems rather disappointing im software engineer id say im asking anything crazy another complicating factor tight userinterface integration i desire scientificworkflowsolutions seem designed handle for instance i would like pass draganddrop event transformation node processing the transformation node two inputs affine transform state input port pointset class knows if affine transform input port dirty waiting dependencies update event held becomes available but event passed node eventinput port marked handled refire affine transform changes due user input thats example one many issues come i dont see adressed anywhere or longrunning forkingjoining branch recieves new input middle crunching previous input so question do happen know good booksarticles workflow design patterns i read or i trying fit square peg round hole know completely different design pattern i know or python package i want regardless buzzwords comes dressed ive rolled solution top enthoughttraits im perfectly happy either feels like rough shoddy reinvention wheel except i cant seem find wheels anywhere internet note im looking webframeworks graphical workflow designers specialpurpose tools just something conceptually like pyutilibworkflow including documentation featureset i work edit im reading reflection issue the requirements one tack onto workflow architecture diverse single shoe fits do want tight integration disk storage tight integration web frameworks asynchronicity mix custom finite state machine logic task dispatch they valid requirements largely incompatible make senseless mixes however lost looking generic workflow system solve arbitrary problem like looking generic iterator solve custom iteration problem iterators primarily reusability cant reuse redblacktree iterator iterate tensor their strength lies clean seperation concerns definition uniform interface what im looking started writing going pretty cool look like base general implementationagnostic workflowdeclaration minilanguage

mytaskx return outputs x taskinputsxint yfloat outputszfloat def mytaskx return outputs z xy mytasky mytasky redundant illustration inputsoutputs matching name metadata autoconnect what decorators return taskcompositetaskworkflow declaration class instead type constraints metadata required workflowtype hand easily added syntax now concise pythonic declaration fed workflow instance factory returns actual workflow instance this declaration language fairly general probably need change much different design requirements workflow instantiation factory entirely design requirementsimagination aside common interface deliveringretrieving inputoutput in simplest incarnation wed something like wf workflowfactorymycompositetask wfz lambda result print result register callback zoutput socket wfx feed data x inputsocket wf trivial workflow instance nothing chain contained function bodies together thread inputs bound a quite verbose way chain two functions illustrates idea already achieves goal separating concern keeping definition flow information central place rather spread throughout classes would rather nothing thats less functionality ive got implemented far means i go working project due time ill add support fancier workflow instance factories for instance im thinking analyzing graph dependencies identify forks joins tracking activity generated input supplied workflowinstance level elegant load balancing cancellation effects specific inputs lost relevance still hogging resources either way i think project separating workflow declaration interface definition implementation instantiation worthwhile effort once i nontrivial types workflow instances working well i need least two project im working ive realized i hope find time publish public project despite diversity design requirements workflow systems groundwork covered makes implementing specific requirements lot simpler and instead single bloated workflow framework swiss army knife easily switchedout custom solutions could grow around core realizing i need split code two different workflow instance types rather trying bash design requirements one solution turned square peg round hole i mind two perfectly complementary holes pegs,3

put qwidget inside another qwidget background set colour you use layout parent qwidget adjust width margin side done within qt designer edit here steps take qt designer achieve select frame widget containing text widget break layout add new qwidget frame widget could name borderwidget set background colour border widget using stylesheet property property editor eg backgroundcolor white nb might help temporarily set contrasting colour easily see going drag drop text widget onto border widget select border widget set layout eg lay out grid select frame widget set layout eg lay out grid select border widget go layout section property editor there see properties like layouttopmargin layoutleftmargin etc used adjust size border,i making changes existing pyqt project the ui created qt designer the relevant part qwidget displays text i trying put margins around text i think simplest way would put border around qwidget whose background color qwidget background white the qwidget qframe i like put white border inside qframe around edge qwidget the closest i come put short vertical horizontal spacers around qwidget displays underlying grey qframe i figure make white i prefer leaving frame

the reason handled differently docs adding translations javascript poses problems javascript code access gettext implementation javascript code access po mo files need delivered server the translation catalogs javascript kept small possible so essentially internal python translation done server but js another file served server contains required translations user language and translation done user side so see completely different strategy django helps adding similar interface js files even though handled completely different way i guess works like rendering template django checks requested locale loads appropriate localisation file serves template js hand served static media get parsed django is you right first part handling templates handling js works i explained note django js translation mechanism treat js translations static files it uses django view generate js file everytime javascriptcatalog mentioned docs linked first line that one problems i encountered such files need generated every request there projects actually let pack js translations static files enable cache properly like djangomediagenerator,when localising django application makemessages command simply parses txt html py files generates po files localising js files need run djangojs command i delved django source figure done differently could someone explain i read production environments apache used serve application files simple proxy like nginx used serve static files greatly reduces load application server with scenario i guess works like rendering template django checks requested locale loads appropriate localisation file serves template js hand served static media get parsed django is its first foray world localisation django i packed full question many answers i seem find therefore post thanks,1

using lists arrays problematic need insertions deletions on operations devastatingly slow large datasets consider using blist listlike api affords olg n insertion deletion,i large array numerical data i need sort insert move values backwards forwards sorted order i previously using simple array now value linked id unique int along ride can i extend array class i need use list tuples what best option,1
the simplest solution would avoid using pipe tail stick using stdin user input instead write tool open follow file want read natively without using tail tail terribly complex tool want reimplement part alternately could create named pipe allow pipe tail program read like file still access stdin if neither options i think going separate library directly polls keyboard might best bet for record pygame actually main loop event pump function call often possible main loop going die it buffer lots lots events pumps set filters discard events care keep ones keypresses the main problem pygame would pretty heavyweight library requiring simple tool i understand hesitation go route oh final option least desirable opinion could abuse keyboard interrupt mechanic create emacslike key chords like press ctrlc ctrlwhatever the ctrlc invokes keyboardinterrupt handler read next character stdin something once done return loop but ugly hacky i even sure would work reliably,setup i playing script pipe tail f highlight certain keywords not big project something i find useful right main loop basically line true line line sysstdinreadline sysstdoutwritehighlightline i like listen certain keypresses loop print marker line log the method i found looks like would work getting keypress described httpcodeactivestatecomrecipes reads single character time stdin work main loop reading entire lines question is way python listen keypresses also reading piped input i wrapped main function try block excepts keyboardinterrupt prints nice little goodbye message instead error stack trace is way piggyback behavior another key i rather use beefy compared small script module like pygame tkinter forced use main loop get access keypresses also i familiar either would behave receiving piped input,1

trailing comma required oneelement tuples having trailing comma larger tuples matter style required its greatest advantage clean diff files multiline large tuples often modified eg configuration tuples,in case single element tuple trailing comma required foo what tuple multiple elements it seems whether trailing comma exists valid is correct having trailing comma easier editing opinion is bad coding style foo foo b foo foo,2
it required singleitem tuples disambiguate defining tuple expression surrounded parentheses for one item longer necessary since perfectly clear tuple however trailing comma allowed make defining using multiple lines easier you could add end rearrange items without breaking syntax left comma accident eg somebigtuple note applies collections eg lists dictionaries tuples,in case single element tuple trailing comma required foo what tuple multiple elements it seems whether trailing comma exists valid is correct having trailing comma easier editing opinion is bad coding style foo foo b foo foo,3
in cases except empty tuple comma important thing parentheses required required syntactic reasons distinguish tuple set function arguments operator precedence allow line breaks the trailing comma tuples lists function arguments good style especially long initialisation split multiple lines if always include trailing comma add another line end expecting add another element instead creating valid expression b c assuming started element list later extended gone wrong perhaps immediately obvious way always include trailing comma avoid trap,in case single element tuple trailing comma required foo what tuple multiple elements it seems whether trailing comma exists valid is correct having trailing comma easier editing opinion is bad coding style foo foo b foo foo,3

you would really prefer stay away polling synchronous operations scale better easier debug if control external protocol make sync i say mostly i think lot people make things async thinking somehow improves performance really makes things difficult you make sync operations appear async local event loop using multiple threads control threads processes select based fsms whatever if control external protocol really async choice poll depending think distribution response times i use sort exponential backoff cap poll period for programs i external main event loop report back via event mechanism event loop,i need implement function involves long async operation send request external server periodically check done needs behave like synchronous operation i following way startlongoperation true operationfinished return sleep i wonder acceptable better solution,1

in opinion i see i think regardless language good idea provides quick overview found file know single class i would make small exception helper classes though python allows nested classes also done quite nicely for possible well in example though simple load module thereby making classes functions available full namespace so say import servicemodel access class using servicemodeldbmodel to import things current namespace servicemodel import servicemodel import dbmodel need class then currently dbmodel,i trying structure app python coming back cjava background i like approach one class per file i like project tree look like service database dbclasspy dbclasspy model dbmodelpy dbmodelpy theservicepy servicetests database dbclasstestspy dbclasstestspy model dbmodeltestspy dbmodeltestspy theservicetestspy is one class per file approach ok python is possible create packagesmodules way packages work like java packages net namespaces ie dbmodeltestspy import servicemodel def test dbmodel,2
q you use class per file style python unusual q use servicemodel import stuff servicemodelinitpy generally frowned upon avoid import python my personal advice python cjava trying bend make look like otherlanguage cause frustration poor user experience keep mind stuff classes python modules functions instance import class module unless need instantiate class especially code uses instances dbmodel passed arguments functions methods need import part code servicemodeldbmodel import dbmodel looks bad prefer servicemodel import dbmodel avoid uppercase letters file names directory names group classes functions logically files rather grouping directories would class per file system,i trying structure app python coming back cjava background i like approach one class per file i like project tree look like service database dbclasspy dbclasspy model dbmodelpy dbmodelpy theservicepy servicetests database dbclasstestspy dbclasstestspy model dbmodeltestspy dbmodeltestspy theservicetestspy is one class per file approach ok python is possible create packagesmodules way packages work like java packages net namespaces ie dbmodeltestspy import servicemodel def test dbmodel,3

you use print message directly enough print tuple extra arguments little addition previous answers python x print function statement printarg arg valid using print statement tuple arg arg this bit different print arg arg one see print aaa bbb aaa bbb print aaa bbb aaa bbb now addition themel answer case using expand argument tuple def pargs aargs args tuple def aargs print args args tuple nothing else used p bb bb result tuple tuple case expanding arguments p def pargs aargs arguments expanding p bb bb result tuple arguments given p so args correct use allowed statement,instead simple debuglog print print error errornumber i would like use log function i expand required looking something like def logcondition message ifdo something printmessage perhaps something call like logcondition error errornumber but i get following syntax error print message syntaxerror invalid syntax is limitation print function way make work if equivalent print i could use i using python way,1
it actually possible assign selfclass python really know the two classes compatible ways userdefined classes either oldstyle newstyle i sure use slots also pawnclass queen pawn object constructed queen constructor expected instance attributes might etc an alternative would sort copy constructor like class chesspieceobject classmethod def fromotherpiececls otherpiece return clsotherpiecex otherpiecey edit see also assigning instances class attribute python,i class describe chess pieces i make type piece board class example pawn queen keen etc i trouble pawn class i want convert queen object class pawn goto th row convert something another i class pawn def initself x selfx x selfy def moveself unit selfy selfy rawinputqueenrookknightbishopqrkb there changed may convert queen knight bishop rook selfy unit print accesible elif selfy unit selfy elif unit selfy else printcant move,3
an object python always instance class there way change without resorting dirty hacks in case probably consider refactoring logic instead letting piece move define kind controller moves pieces if pawn reaches last row controller easily replace piece another,i class describe chess pieces i make type piece board class example pawn queen keen etc i trouble pawn class i want convert queen object class pawn goto th row convert something another i class pawn def initself x selfx x selfy def moveself unit selfy selfy rawinputqueenrookknightbishopqrkb there changed may convert queen knight bishop rook selfy unit print accesible elif selfy unit selfy elif unit selfy else printcant move,1

like said problem described hmm you essentially interested maintaining distribution latent hidden states would true quantities time point however seems confusing problem learning parameters hmm opposed simply inference known hmm you latter problem propose employing solution baumwelch designed former that model already use interestingly go coding discrete hmm problem get algorithm similar describe graphtheory solution the big difference solution tracking possible whereas correct inference algorithm like virterbi algorithm track likely the difference clear overlap range domain multiple possible states could potentially transition state your algorithm might add edges point i doubt compute next day effect count twice essentially anyway could use viterbi algortihm interested best guess recent day i give brief idea modify graphtheory solution instead maintaining edges states maintain fraction representing probability state correct one distribution sometimes called belief state at new day propagate forward belief state incrementing bucket probability parent instead adding edge adding floating point number you also make sure belief state properly normalized sums divide sum update after weight state observation since noisy observation go set impossible states zero probability renormalize you distribution underlying quantities conditioned observations i skipping lot statistical details give idea edit questions the answer question really depends want want distribution recent day get away onepass algorithm like i described if however want correct distribution quantities every single day going backward pass well hence aptly named forwardbackward algorithm i get sense since looking go back step delete edges probably want distribution days unlike i originally assumed of course noticed information used future inform past speak exactly reason need backward pass well really complicated run exact algorithm starting end chain for good overview check christopher bishop piece tutorial videolecturesnet because mentioned addingdeleting edges let clarify algorithm i described previously keep mind single forward pass let total n possible permutations quantities belief state sparse vector n elements long called v the first step receive observation sum populate vector setting possible values probability renormalize the next step create new sparse vector v iterate nonzero entries v increment probability v entries v within then zero entries v possible according new observation renormalize v throw away v repeat forever v always correct distribution possibilities by way things get way complex noisy observations large states continuous states for reason pretty hard read literature statistical inference quite general,i problem game i making i think i know solutionor solution apply sure ‘pieces’ fit together how game works how approach number guessing gamewith twist algorithm users given items valuevalues change every day program aware change price for example apple pears oranges they get chance choose combo like ie apples pears oranges the output computer gets total valuein example currently the computer try guess which obviously won’t able get correctly first turn value quantityday valueday apple pears orange total the next turn user modify numbers total quantity percent may chose i’ll use example the prices fruit changeat random total value may change based alsofor simplicity i changing fruit prices example using example day game user returns value day here example quantityday changeday valueday quantityday changeday valueday i hope tables show right i manually space hopefully screen work let know i try upload screenshot i trying see i figure quantities timeassuming user patience keep entering numbers i know right restriction total value cannot i cannot within accuracy right user entering forever what i done far i taken values fruit total value fruit basket that’s given created large table possibilities once i list possibilities i used graph theory created nodes possible solution i create edgeslinks nodes dayfor example day day within change i delete nodes edgeslinks nodes user keeps playing i also delete entire paths path becomes dead end this great narrows choices i’m stuck i want narrow choices even i’ve told hidden markov problem trickier version states changingas see new nodes added every turn oldnonprobable ones removed helps i got amazing answerwith sample code python implementation baumwelch modelits used train data example implementation baumwelch what i think needs donethis could wrong now i narrowed results i basically trying allow program try predict correct based narrowed result base i thought possible several people suggesting solved hidden markov model i think i run several iterations datausing baumwelch model probabilities stabilizeand get better turns user the way hidden markov models able check spelling handwriting improve make errorserrors case pick basket deleted upon next turn improbable two questions how i figure transition emission matrix states first equal for example states equally likely something must used dedicate probability states changing i thinking using graph i made weight nodes highest number edges part calculation transitionemission states does make sense better approach how i keep track changes states as new baskets added old ones removed becomes issue tracking baskets i though hierarchical dirichlet process hidden markov modelhdphmm would i needed exactly sure apply sorry i sound bit frustratedits bit hard knowing problem solvable able conceptually grasp needs done as always thanks time advicesuggestions would greatly appreciated,3

i compared performance c extension vs ctypes wrapper in particular test difference x there multiple calls c library ctypes wrapper also executing python code the running time c library short made extra overhead python code even significant so ratio likely different significant case,i functions written c game project these functions get called quite lot times per second the functions written c raw speed now easiest way include functions python use ctypes the alternative write c extension python around functions takes quite bit extra effort so i wondered including initial loading dll big overhead ctypes i using python standard cpython release i want use external library like cython i know question asked i seen much information performance comparison two options,3

instead letting excelmicrosoft dictate store datetime would less trouble work rely standardobvious way things process objects according standards domain python way datetime objects inside

the reason observation aes block cipher encrypt data blocks bits bytes to normally used mode operation allow encrypting larger pieces data padding mode it looks like python decrypting function decrypting undo padding giving result you using pkcs padding appends number bytes least one value number final length multiple block length for bytes string one needs append bytes value ascii backspace character terminal moves cursor one left times resulting xxx overprinting abc for bytes string one needs append bytes value this horizontal tabulator making xxx appear quite right either find supply right padding mode decryption function option remove padding check last byte decryptstring convert number using ascii value take many bytes end decryptstring you also check value you first interpreting output string ie applying encoding like utf ascii,i input string i encrypting mysql aesencrypt decrypting python mysql aesdecrypt i printed tests decrypted string print decryptstring print sxxx decryptstring print lendecryptstring print selftohexdecryptstring when input string length ie abcdefgh tests output abcdefgh xxxdefgh xxxxxxxxxxxxxxxx if input string length ie abcdefg abcdefg abcdefg xxx xxxxxxxxxxxxxxxx i found ending char progressively decreases length input string increases why difference if i use php aes encrypt instead mysql aesencrypt ending char x i using use third party python aes lib,1

why would exit you iterating elements range exit condition run elements rebinding name change anything inside iterable if want break prematurely use break range break,python noob please explain loop exit range print hello world print next regards,1
because done range created array elements like going one in programming languages called foreach loop otherwise another way,python noob please explain loop exit range print hello world print next regards,3
because whatever means element whatever loop body executed setting element there rule says end iteration must still element whatever reassigning loop body effect whatsoever often loop body executes value hold next iteration,python noob please explain loop exit range print hello world print next regards,1
because python loop count iterates range produces iterable list python x iterable iterated each time loop body executed next item pulled changes make loop body iteration variable affect memory next value supposed that saved elsewhere generally affect simply use break,python noob please explain loop exit range print hello world print next regards,3
you iterating range object collection values ranging there logic behind collection numbers the item set syntax essentially loops every element set breaking every item looped your code equivalent c loop would produce desired result int if want break loop break loop range print hello world break print,python noob please explain loop exit range print hello world print next regards,2
in python loop loop like c java instead iteration iterable in case assuming python x range way range function returns list a python list iterable therefore used loop language assigning variable first second third element time execute body part it matter alter variable body python pick next element list elements processed consider loop really different print hello world print turn also quite similar print hello world print assignment break loop,python noob please explain loop exit range print hello world print next regards,1

generally i use classes implement logical set capabilities thing rest program i reason thing worry little concerns make implementation anything part core abstraction thing usually method this

changing interface i small core set methods rewrite external functions written terms methods just work i find insisting operations class x methods class x leads overcomplicated classes it depends code i writing though for programs i model collection objects whose interactions give rise behavior program important functionality closely coupled single object implemented methods scattering utility

python eliminate overhead structures like sorry its dynamic nature makes compiler optimizations difficult but i know language would eliminate overhead introduced keeping things dictionaries dict owner probably includes dictionaries creating inside object they marked noowner dictionaries object instances what use slots add slots names fields class attribute python use efficient implementation class it get rid dictionary used hold attributes if dictionaries rewritten use lists would improve situation lists memory efficient dictionaries for best efficiency rework system use numpy arrays each attribute class would become sized array each element stored efficiently spacewise case alternatively could checkout pypy it provides alternate implementation python jit well various timespace optimizations might help sysgetsizeof reporting think reporting sysgetsizeofmyobjcontainer reports size class object size actual container objects you want sysgetsizeofmyobjcontainer similar even accurate include anything besides base object it take account dictionary holding attributes it report size third row report,i got results heapy unclear exactly mean index count size cumulative kind class dict class dict owner dict myobjcontainer myobjcontainer myobj class truefalse values number values could stored bytes i array i really see consume mb memory i like bring mb possible much data inside object organized dictionaries ease access the dictionaries change rather pointless would cause much overhead would beneficial pack data number bitwise operators i able store entire data object bytes i hoping compiler would sort thing automatically like languages seems opposite the class inherits builtin type object reason use decorators would cause much overhead also curious dict owner means consuming half memory edit sysgetsizeofmyobjcontainer indeed reporting bytes this insane i used dictionaries i need access data based index as far i concerned compiler get rid structures access values directly is better way i imagine lists answer,3
