Python中的Try / Except：如何正确忽略异常？ [英] Try/Except in Python: How do you properly ignore Exceptions?

问题描述

当您只想尝试 - 除了不处理异常，您如何在Python中执行此操作？

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

以下是正确的方法？

try:
    shutil.rmtree(path)
except:
    pass

推荐答案

try:
  doSomething()
except: 
  pass

或

try:
  doSomething()
except Exception: 
  pass

区别是，第一个也会抓住 KeyboardInterrupt ， SystemExit 和类似的东西，直接从 exception.BaseException 而不是 exceptions.Exception 。
请参阅文档了解详情：

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.
