Imibuzo Ebuzwa Rhoqo

Siyintoni isabelo esibotshelelweyo kwiPython?

Isabelo esikhonkxiweyo sikuvumela ukuba unikeze ixabiso elifanayo kwiinguqu ezininzi kwinkcazo enye, njenge a = b = c = 10. Kwinqanaba le-bytecode, iPython ivavanya intetho yesandla sasekunene kanye, emva koko iphinda isiphumo kwisitaki isebenzisa DUP_TOP kwaye iyigcine kwithagethi nganye ukusuka ekhohlo ukuya ekunene. Oku kwenza isabelo esibotshelelweyo sibe mfutshane kwaye sisebenze kakuhle xa sithelekisa nokubhala iinkcazo zesabelo ezahlukeneyo.

Ngaba iPython bytecode iyisingatha njani izabelo ezibotshelelweyo ngokwahlukileyo kwizabelo ezininzi?

Ngesabelo esibotshelelweyo, intetho ivavanywa kube kanye kuphela kwaye ixabiso lesiphumo liphindwaphindwa kwisitaki soguqulo lwethagethi nganye. Ngokwahlukileyo, ukubhala izabelo ezahlukeneyo ezifana a = 10; b = 10 ivavanya ingokoqobo ngokuzimeleyo kumgca ngamnye. Ungahlola lo kuziphatha usebenzisa i-Python's dis imodyuli, echitha imisebenzi kwi-bytecode imiyalelo yabo, ityhila DUP_TOP kunye STORE_NAME imisebenzi ebandakanyekayo.

Ingaba kukho imigibe enesabelo esibotshelelweyo sezinto eziguquguqukayo?

Ewe - impazamo eqhelekileyo ibhala < ikhowudi> a = b = [] , edibanisa zombini izinto eziguquguqukayo efanayo into yoluhlu kunokuba wenze uluhlu oluzimeleyo olubini. Ukuguqula enye kuya kuchaphazela enye. Oku kwenzeka ngenxa yokuba i-bytecode iphinda ireferensi, hayi into ngokwayo. Ukuqonda le nqanaba lokuziphatha kwe-bytecode kunceda abaphuhlisi baphephe iibugs ezifihlakeleyo. I-Mewayz igubungela i-semantics eguquguqukayo xa ithelekiswa ne-semantics engaguqukiyo kuzo zonke iimodyuli zayo ezingama-207 zePython, ezifumaneka nge-19 yeedola / ngenyanga.

Ndingafunda phi ngakumbi malunga nePython bytecode kunye nobuchwephesha bangaphakathi?

I dis esemthethweni yamaxwebhu sisiqalo esihle sokuhlola imiyalelo ye-bytecode. Kwindlela ecwangcisiweyo, yezandla-kwindlela yokufunda egubungela abangaphakathi bePython ecaleni kwezakhono zeprogram esebenzayo, iMewayz ibonelela ngeemodyuli eziyi-207 ezenziwe ngobuchule kwi-19 yeedola / mo. Ezi modyuli ziqhubela phambili ukusuka kwimiba yesiseko efana nokwahluka kwezabelo ukuya kwizihloko eziphambili ezinjengohlalutyo lwe-bytecode, ulawulo lwenkumbulo, kunye nokuziphatha kwetoliki.
