这里介绍Python的迭代器、生成器、Iteration Protocol迭代协议 迭代器 迭代器是一个会记住遍历位置的对象。一方面,当迭代器中的元素被访问过后,就无法再次访问之前的元素。因为其是单向遍历的;另一方面,迭代器从第一个元素开始访问,当所有的元素都被访问完,就不能再次使用。具体地,可使用iter()函数通过 可迭代对象 ...
it's valuable to note that Python works over the notion of iterator for iterations. What decides which value will come and its order/sequentiality it's the iterator. some objects outputs values in a different order they are added to the object (e.g. set class). more important in this ...
