Python:是否可以访问“finally"子句中的返回值? [英] Python: Is it possible to access the return value inside the `finally` clause?

问题描述

我在 try 子句中有一个 return 语句:

I have a return statement inside a try clause:

def f():
    try:
        return whatever()
    finally:
        pass # How do I get what `whatever()` returned in here?

是否可以在finally 子句中获取返回值?

Is it possible to get the return value inside the finally clause?

这更像是一个理论问题，所以我不是在寻找像将其保存到变量这样的解决方法.

This is more of a theoretical question, so I'm not looking for a workaround like saving it to a variable.

推荐答案

不，它不是 - finally 子句的内容独立于返回机制；如果您确实想查看返回的值，则必须按照您提到的方式进行操作，并将其显式保存在范围内的某个位置.

No, it isn't - the finally clause's content is independent from return mechanics; if you do want to see what value is returned you'd have to do as you mentioned and explicitly save it somewhere that's in-scope.
