itertoolsgroupby collects together contiguous items key if want items key sort selfdata first mid group itertoolsgroupby sortedselfdatakeyoperatoritemgetter keyoperatoritemgetter

i data selfdata list when i run code mid group itertoolsgroupbyselfdata keyoperatoritemgetter listgroup i get list i want but i use instead mid group itertoolsgroupbyselfdata keyoperatoritemgetter group second number tuples i get list even though tuples nd position

some great answers i haven’t seen one puts together have… since form one input need access value particular one there ways straightforward might use form’s elements property forms documentgetelementbyidchoiceformelementschoicevalue

don use class factory silly you need consistent interface across implementations class jobaobject def dojobself arg print job arg class jobbobject def dojobself arg print job b arg jobtypes job joba job jobb jobtype job univar job jobtypesjobtype jobdojobunivar hell jobs keep state classes either functions instead def jobaarg def jobbarg job jobtypesjobtype jobunivar

what want probably possible using com python tutorial it messy hard code hard debug and way work mac instead i i would try take problem excel for instance python i would first directly access mysql i would parse second xls file using xlrd with results mysql query parsed xls file python data structures replicating behaviour vlookup easy i would write results output xls file using xlwt

i looking way automate entire process uses excel amp odbc queries i know excel use odbc driver run queries mysql database but i need query triggered programmatically the individual steps program script able open excel file run mysql query query change values query hits database come excel file save results query excel file sheet use results vlookups another sheet excel file save results vlookups close file flexible language addons necessary anything would help i looking run windows mac

you actually using inheritance original code code contains severe bug masks appearing you create instance superclass stores jobtype univar instantiates either option option stores reference the subclasses initialised data jobtype univar attributes override init donothing methods avoid error when call jobselectjob superclass explicitly delegates jobchoice attribute so useful inheritance going overridden everything superclass subclasses instead jobselect instance different subclasses depending jobtype using method resolution call right code jobselect always superclass contains option option explicitly delegates the serious bug i mentioned neither option option actually contains information job job methods anything interesting you call print univar work would normally print selfunivar get univar job seems work global called univar as soon start anything complicated scheme fall badly srgerg answer good example could actually use inheritance factory functions solve problem catplusplus answer good example use appropriate tools simple code example may need real requirements complex got written moment

raise raise exceptions first place a lone raise exception handler propagates exception external handlers

that code kind ridiculous bizarre way things pretty clear going the list b c d list exceptions since exception raise try block immediately handled appropriate except handler succession except b except c except d handlers thus code equivalent print b print c print d except throw uncaught exception b c d exception

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

i took look python data model documentation if skip ahead class instances section see crucial explanation attribute assignments deletions update instance’s dictionary never class’s dictionary so example aname introduce new key name dict after access name attribute standard attribute lookup mechanism looks dict first

i defined simple class class myclassobject name google and i creating instance call name attribute myclass aname google also calling directly class myclassname google so far i background c java i call myclassname static invocation calling static members instances fine but i observing till i set aname another value changing myclassname also affecting aname once i set aname changing myclassname affect aname begin different values you see whole experiment class myclassobject name google myclassname google myclass aname google myclassname yahoo aname yahoo myclassname hello world aname hello world myclassname hello world myclassname another trick myclassname another trick aname another trick aname i changed value aname i changed value myclassname another trick myclassname changed aname i changed value i would like someone explain reason behind behavior thanks
