如何正确忽略异常 [英] How to properly ignore exceptions

问题描述

当您只想执行try-except但不处理异常时，如何在Python中完成呢？

When you just want to do a try-except without handling the exception, how do you do it in Python?

以下是正确的处理方式吗？

Is the following the right way to do it?

try:
    shutil.rmtree(path)
except:
    pass

推荐答案

try:
    doSomething()
except: 
    pass

或

try:
    doSomething()
except Exception: 
    pass

不同之处在于第一个也将捕获 KeyboardInterrupt ， SystemExit 之类的东西，它们直接从 exceptions.BaseException 而不是 exceptions.Exception 。

The difference is that the first one will also catch KeyboardInterrupt, SystemExit and stuff like that, which are derived directly from exceptions.BaseException, not exceptions.Exception.
