我可以从python中的finally块获取异常吗？

问题描述

我的脚本中有一个 try / finally 子句。可以从 finally 子句中获取确切的错误消息。

I have a try/finally clause in my script. Is it possible to get the exact error message from within the finally clause?

推荐答案

不，在终于时间 sys.exc_info 是全无，是否有异常
或不。使用：

No, at finally time sys.exc_info is all-None, whether there has been an exceptionor not. Use:

try:
  whatever
except:
  here sys.exc_info is valid
  to re-raise the exception, use a bare `raise`
else:
  here you know there was no exception
finally:
  and here you can do exception-independent finalization
