如何循环通过发电机 [英] How to loop through a generator

问题描述

一个发电机如何循环?我是这样想的:

How can one loop through a generator? I thought about this way:

gen = function_that_returns_a_generator(param1, param2)
if gen: # in case the generator is null
    while True:
        try:
            print gen.next()
        except StopIteration:
            break

还有更Python化的方式吗?

Is there a more pythonic way?

推荐答案

简单

for x in gen:
    # whatever

可以解决问题.请注意，if gen始终返回True.

will do the trick. Note that if gen always returns True.
