该接口在 collections.abc.Iterator 抽象基类中制定,该类定义了 __next__ 抽象方法,且继承自 Iterable 类;__iter__ 抽象方法则在 Iterable 类中定义,如下图所示 2.2 从可迭代对象生成迭代器(for 循环的本质) 给出...
迭代器是一个可以记住遍历位置的对象。 An iterator is an object that can remenber to traverse the location. 迭代器对象从集合的第一个元素开始访问,直到所有的元素被访问完结束。迭代器只能往前不会后退。 The Iterator onject starts from the first element of the collection until all the elements are ac...

An object can function as an iterator if it implements next(). Container-like objects usually support protocol 1. Iterators are currently required to support bothprotocols. The semantics of iteration come only from protocol 2; protocol 1 is present to makeiteratorsbehave like sequences; in particu...
