在Python中，我应该在if块中返回后使用else吗？ [英] In Python, should I use else after a return in an if block?

问题描述

首先，我在 PEP 8 中找不到答案。这并不意味着它不在那里。

First, I couldn't find an answer to this in PEP 8. That doesn't mean it isn't in there. Feel free to point me at it.

您最喜欢哪种风格？

：

if spam:
    # Do stuff.
    return eggs
else:
    # Maybe do other stuff.
    return parrots

或第二个：

if spam:
    # Do stuff.
    return eggs
# Maybe do other stuff.
return parrots

推荐答案

会返回鹦鹉，当你不返回鸡蛋，那么第一个更清楚。
但是如果你想捕获一个错误或类似的东西，第二个更好。

It depends, if you would return parrots, when you do not return eggs, then the first one is more clear. But if you are trying to catch an error or something like that, the second one is better.
