在Python 中,只要一个函数function中使用了 yield 这个关键字,就代表这个函数function每次调用时都是返回一个生成器对象 generator object,注意:包含 yield 语句的函数function本身并不是生成器generator,它仍然是一个函数function。生成器generator是一个类class,而不是函数function。而 yield 的作用就相当于让 Python 帮...
python 迭代器生成器 Generators are functions that can be paused and resumed on the fly, returning an object that can be iterated over. Unlike lists, they arelazyand thus produce items one at a time and only when asked. So they are much more memory efficient when dealing with large datasets...

那么是不是就说明 Python 语言的设计比 Go 更加符合 Occam's Razor 的原则了呢? 恐怕并不尽然。虽然 Python 代码简短,但是需要用户理解更多概念(generator,iterator,以及它们和 functions 以及 queues 的潜在关系)—— 这也是一种开销。 这里只是提醒大家关注保持设计的简洁。不在于挖坑比较 Python 和 Go 语言。
Iterable is a category of objects which can return its element every other time. In fact, any instance carries method__iter__()or__getitem__()will be considered as iterable. There are many iterable objects in python: list, str, tuple, dict, file, xrange... ...
if functions in Python are objects, couldn't I assign the length to a variable of this object that would be accessible to the new generator? Functions are objects, but you cannot assign new attributes to them. The reason is probably to keep such a basic object as efficient as possible. ...
