Kukhishwe ukukhishwa okusha okuzinzile kolimi lokuhlela oludumile lwePython.
I-Python iwulimi lohlelo olusezingeni eliphezulu, oluhloselwe ukuthuthukisa ukukhiqiza konjiniyela kanye nokufundeka kwekhodi. Izici eziyinhloko ukuthayipha okuguquguqukayo, ukuphathwa kwenkumbulo okuzenzakalelayo, ukuhlola okugcwele, indlela yokubamba okuhlukile, ukusekelwa kwekhompyutha enezintambo eziningi, izakhiwo zedatha ezisezingeni eliphezulu.
I-Python ulimi oluzinzile futhi olusabalele. Isetshenziswa kumaphrojekthi amaningi nasemandleni ahlukahlukene: njengolimi oluyisisekelo lokuhlela noma ukudala izandiso nokuhlanganisa izinhlelo zokusebenza. Izindawo eziyinhloko zohlelo lokusebenza: ukuthuthukiswa kwewebhu, ukufunda ngomshini nokuhlaziywa kwedatha, i-automation kanye nokuphathwa kwesistimu. Njengamanje iPython ikleliswe endaweni yesithathu ezilinganisweni I-TIOBE.
Izinguquko eziyinhloko:
Umhlahleli omusha osebenza kahle kakhulu osuselwe kuhlelo lolimi lwe-PEG.
Enguqulweni entsha, umhlaseli wamanje we-Python osuselwe ku-LL(1) wolimi (i-KS-grammar) uthathelwa indawo umhlaziyi osebenza kahle kakhulu futhi ozinzile osuselwe ku-PEG (PB-grammar). Abahlaluli bezilimi ezimelelwe uhlelo lolimi lwe-KS, njengabahlaluli be-LR, badinga isinyathelo esikhethekile sokuhlaziya isichazamazwi esihlukanisa okokufaka ngokuya ngesikhala esimhlophe, izimpawu zokubhala, nokunye. Lokhu kuyadingeka ngoba laba bahlaziyi basebenzisa ukulungiselela ukucubungula ezinye izinhlelo zolimi ze-KS ngesikhathi somugqa. I-RV grammars ayidingi isinyathelo esihlukile sokuhlaziya isichazamazwi, futhi imithetho yayo ingabekwa kanye neminye imithetho yohlelo.
Ama-opharetha amasha nemisebenzi
Ama-opharetha amabili amasha angeziwe ekilasini le-dict eyakhelwe ngaphakathi, | yokuhlanganisa izichazamazwi kanye |= ukuze kuthuthukiswe.
Imisebenzi emibili emisha yengezwe ku-str class: str.removeprefix(isiqalo) kanye ne-str.removesuffix(isandiso).
Thayipha ukusikisela kwezinhlobo zeqoqo ezakhelwe ngaphakathi
Lokhu kukhishwa kufaka usekelo lwe-syntax yokukhiqiza kuwo wonke amaqoqo ajwayelekile atholakalayo njengamanje.
