Python返回语句错误"“返回"外部函数" [英] Python return statement error " 'return' outside function"

问题描述

运行以下代码时(在 Mac OS X 10.7 的 Mac 上使用 Python 2.7.1)

When running the following code (in Python 2.7.1 on a mac with Mac OS X 10.7)

while True:
    return False

我收到以下错误

SyntaxError: 'return' outside function

我已经仔细检查了错误的制表符和/或空格.当我使用推荐的 4 个缩进空格时，我可以确认代码失败并出现上述错误.当 return 放在其他控制语句(例如 if、for 等)中时，也会发生这种行为.

I've carefully checked for errant tabs and/or spaces. I can confirm that the code fails with the above error when I use the recommended 4 spaces of indentation. This behavior also happens when the return is placed inside of other control statements (e.g. if, for, etc.).

任何帮助将不胜感激.谢谢！

Any help would be appreciated. Thanks!

推荐答案

return 语句只在函数内部有意义:

The return statement only makes sense inside functions:

def foo():
    while True:
        return False
