Since functions can be passed into functions, that also means that functions can accept another function as an argument. Thefilterfunction assumes its first argument is a function. You can think of thefilterfunction as pretty much the same as this function: deffilter(predicate,iterable):return(it...
Remember that arguments arepassed by assignmentin Python. Since assignment just creates references to objects,there’s no aliasbetween an argument name in the caller and callee, and so no call-by-reference per se. 我们常说参数的传递分为按值传递与按引用传递,Python中的passed by assignment该如何理...

Python passed by assignment 说了这么多,Python中的passed by assignment该怎么理解?Python中类型没有像.NET那样分为值类型与引用类型。Python中所有类型的值都是对象,这些对象分为可变对象与不可变对象两种: 不可变类型 float、int、str、tuple、bool等
