Imibuzo Evame Ukubuzwa

Siyini isabelo esiboshwe ngamaketanga kuPython?

Isabelo esiboshwe ngamaketanga sikuvumela ukuthi unikeze inani elifanayo kokuguquguqukayo okuningi esitatimendeni esisodwa, njengokuthi a = b = c = 10. Ezingeni le-bytecode, i-Python ihlola inkulumo engakwesokudla kanye, bese iphinda umphumela kusitaki isebenzisa DUP_TOP bese iwugcina kuthagethi ngayinye ukusuka kwesokunxele kuye kwesokudla. Lokhu kwenza isabelo esiboshiwe sibe mfushane futhi siphumelele uma kuqhathaniswa nokubhala izitatimende zezabelo ezihlukene.

Ingabe i-Python bytecode iyisingatha kanjani izabelo eziboshwe ngokuhlukile kunezabelo eziningi?

Ngomsebenzi ozokwenziwa oboshelwe, isisho sihlolwa kanye kuphela futhi inani eliwumphumela liphindeke kabili esitakini ngokuhlukahluka ngakunye okuqondiwe. Ngokuphambene, ukubhala imisebenzi ehlukene efana ne-a = 10; b = 10 ihlola ngokwezwi nezwi ngokuzimela emgqeni ngamunye. Ungahlola lokhu kuziphatha usebenzisa imojuli ye-Python's dis, ehlukanisa imisebenzi ibe yimiyalelo ye-bytecode, eveza DUP_TOP kanye STORE_NAME nemisebenzi ehilelekile.

Ingabe zikhona izingibe ngomsebenzi ozokwenziwa ngezinto eziguqulekayo?

Yebo — iphutha elivamile ukubhala a = b = [], okuhlanganisa kokubili okuguquguqukayo ento efanayo yohlu kunokudala izinhlu ezimbili ezizimele. Ukuguqula eyodwa kuzothinta enye. Lokhu kwenzeka ngoba i-bytecode iphinda ireferensi, hhayi into ngokwayo. Ukuqonda lokhu kuziphatha kweleveli ye-bytecode kusiza onjiniyela bagweme iziphazamisi ezicashile. I-Mewayz ihlanganisa i-semantics eguquguqukayo uma iqhathaniswa nengaguquleki kuwo wonke amamojula ayo angu-207 Python, atholakala ngo-$19/mo.

Ngingakufunda kuphi okwengeziwe mayelana ne-Python bytecode kanye nobunjiniyela bangaphakathi?

Amadokhumenti emojula ye-dis esemthethweni ayisiqalo esihle sokuhlola imiyalelo ye-bytecode. Ngomzila wokufunda ohlelekile, osebenza ngezandla ohlanganisa abangaphakathi bePython eceleni kwamakhono asebenzayo wokuhlela, i-Mewayz inikeza amamojula aklanywe ngobuchule angu-207 ngo-$19/mo. Lawa mamojuli aqhubekela phambili esuka emicabangweni eyisisekelo efana nokwabiwa okuguquguqukayo aye ezihlokweni ezithuthukile njengokuhlaziywa kwe-bytecode, ukuphathwa kwenkumbulo, nokuziphatha komtoliki.
