def newfunc(*fargs, **fkeywords): newkeywords = keywords.copy() newkeywords.update(fkeywords) return func(*(args + fargs), **newkeywords)newfunc.func = funcnewfunc.args = argsnewfunc.keywords = keywordsreturn newfunc

python標(biāo)準(zhǔn)庫(kù)里面的代碼，請(qǐng)問(wèn)newfunc.func = funcnewfunc.args = argsnewfunc.keywords = keywords這三句話(huà)好像沒(méi)什么用處啊？

問(wèn)題解答

沒(méi)有用的話(huà)，你調(diào)用的時(shí)候，newfunc的參數(shù)從哪里來(lái)呢
