tus kheej . _ chav kawm _ yog ib qho kev siv rau hom kev piv txwv tam sim no. Piv txwv li ntawm abstract1, qhov ntawd yuav yog abstract1 chav kawm nws tus kheej, uas yog qhov koj tsis xav nrog kev paub daws teeb meem chav kawm.
Ib yam li ntawd, nws tau nug, _ chav kawm _ hauv Python yog dab tsi?
"_ ib _ "yog ib txoj kev rov kho dua hauv cov chav kawm python . Nws yog lub npe hu ua constructor nyob rau hauv object oriented tswvyim. Txoj kev no hu ua thaum ib yam khoom raug tsim los ntawm cov chav kawm thiab nws tso cai rau chav kawm los pib cov yam ntxwv ntawm a chav kawm.
Tsis tas li ntawd, kev siv _ hu _ hauv Python yog dab tsi? Cov _ hu rau_ txoj kev enables Python programmers los sau cov chav kawm uas cov piv txwv coj zoo li cov haujlwm. Ob qhov haujlwm thiab qhov piv txwv ntawm cov chav kawm zoo li no hu ua callables. Nws tseem tuaj yeem ua rau overload tus neeg teb xov tooj "+" nrog rau tag nrho lwm tus neeg ua haujlwm rau lub hom phiaj ntawm koj tus kheej chav kawm.
Ntxiv mus, tus kheej _ dict _ Python yog dab tsi?
Yeej nws muaj tag nrho cov cwj pwm uas piav txog cov khoom hauv nqe lus nug. Nws tuaj yeem siv los hloov lossis nyeem cov cwj pwm. Daim ntawv thov los ntawm cov ntaub ntawv _ hais_ Ib phau ntawv txhais lus lossis lwm yam khoom siv los khaws cov khoom (sau tau) yam ntxwv. Nco ntsoov, txhua yam yog ib yam khoom hauv Python.
def _ init _ yog dab tsi?
_ib_ yog tus tsim qauv rau chav kawm. Cov tus kheej parameter hais txog qhov piv txwv ntawm cov khoom (zoo li qhov no hauv C ++). Chav Kawm Point: def _init_ ( tus kheej , x, y): tus kheej.

Dab tsi yog qhov txawv ntawm chav kawm sab hauv thiab cov chav nested?
Cov chav kawm uas tau tshaj tawm yam tsis siv qhov zoo li qub yog hu ua chav kawm sab hauv lossis chav kawm tsis zoo li qub. Cov chav kawm Staticnested yog chav kawm zoo li lwm cov tswv cuab zoo li qub ntawm cov chav kawm sab nrauv. Txawm li cas los xij, cov chav kawm sab hauv yog khi toinstance thiab nws tuaj yeem nkag mus rau cov tswv cuab ntawm pawg enclosingclass

Peb puas tuaj yeem muaj ntau chav kawm pej xeem hauv chav kawm hauv Java?
Yog, nws ua tau. Txawm li cas los xij, muaj peev xwm tsuas yog ib pawg pej xeem ib. java cov ntaub ntawv, raws li publicclasses yuav tsum muaj tib lub npe raws li cov ntaub ntawv qhov chaw. OneJava cov ntaub ntawv tuaj yeem muaj ntau chav kawm nrog kev txwv uas tsuas yog ib qho ntawm lawv tuaj yeem ua pej xeem
Chav kawm piav qhia txog tus qauv ntawm chav kawm yog dab tsi?
Nyob rau hauv object-oriented programming, ib chav kawm yog ib tug template txhais ntawm txoj kev s thiab txawv txawv s nyob rau hauv ib tug tej yam khoom. Yog li, ib yam khoom yog ib qho piv txwv tshwj xeeb ntawm chav kawm; nws muaj cov txiaj ntsig tiag tiag tsis yog hloov pauv. Cov qauv ntawm ib chav kawm thiab nws cov subclasses yog hu ua chav kawm hierarchy
