Lipotso Tse Botsoang Hangata

Mosebetsi o tlanngoeng ho Python ke ofe?

Kabelo ea ketane e u lumella ho fana ka boleng bo tšoanang ho mefuta e mengata ka polelo e le 'ngoe, joalo ka a = b = c = 10. Boemong ba bytecode, Python e lekola polelo e ka letsohong le letona hang, ebe e pheta sephetho ho stack e sebelisa DUP_TOP ebe e e boloka ho sepheo se seng le se seng ho tloha ho le letšehali ho ea ho le letona. Sena se etsa hore likabelo tse tlanngoeng e be tse khutšoane hape li sebetse hantle ha li bapisoa le ho ngola lipolelo tse arohaneng tsa mosebetsi.

Python bytecode e sebetsana joang le likabelo tse tlanngoeng ka liketane ka tsela e fapaneng le likabelo tse ngata?

Ka kabelo e tlanngoeng, polelo e hlahlojoa hang feela 'me boleng ba sephetho bo kopitsoa holim'a stack bakeng sa phetoho e 'ngoe le e 'ngoe e reriloeng. Ho fapana le hoo, ho ngola likabelo tse arohaneng joalo ka a = 10; b = 10e lekola taba ea sebele e ikemetseng bakeng sa mola o mong le o mong. O ka hlahloba boits'oaro bona o sebelisa Python's dis module, e arolang lits'ebetso ho latela litaelo tsa bona tsa bytecode, e senola DUP_TOP le STORE_NAME ts'ebetso e amehang.

Na ho na le maraba ka mosebetsi o tlanngoeng bakeng sa lintho tse feto-fetohang?

E - phoso e tloaelehileng ke ho ngola a = b = [], e kopanyang mefuta e 'meli ho e tšoanang lenane la ntho ho e-na le ho theha manane a mabeli a ikemetseng. Ho fetola e 'ngoe ho tla ama e mong. Sena se etsahala hobane bytecode e pheta referense, eseng ntho ka boeona. Ho utloisisa boitšoaro bona ba boemo ba bytecode ho thusa bahlahisi ho qoba liphoso tse poteletseng. Mewayz e akaretsa semantics e ka fetohang vs e ke keng ea fetoha ho pholletsa le li-module tsa eona tse 207 tsa Python, tse fumanehang ka $19/mo.

Nka ithuta ho eketsehileng kae ka Python bytecode le mak'henike a ka hare?

Litokomane tsa molao tsa dis ke sebaka se setle sa ho qala ho hlahloba litaelo tsa bytecode. Bakeng sa mokhoa o hlophisitsoeng, o sebetsanang le matsoho o koahelang basebetsi ba Python hammoho le tsebo e sebetsang ea lenaneo, Mewayz e fana ka li-module tse 207 tse entsoeng ka bokhabane ho $ 19 / mo. Li-module tsena li tsoela pele ho tloha ho menahano ea mantlha joalo ka mosebetsi o fapaneng ho ea ho lihlooho tse tsoetseng pele joalo ka tlhahlobo ea bytecode, taolo ea memori, le boits'oaro ba bafetoleli.
