python - 如何正确忽略异常(How to properly ignore exceptions)

Question

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

(如果您只是想尝试 - 除非不处理异常，您如何在Python中执行此操作？)

Is the following the right way to do it?

(以下是正确的方法吗？)

try:
    shutil.rmtree(path)
except:
    pass

Answer 1

try:
  doSomething()
except: 
  pass

or

(要么)

try:
  doSomething()
except Exception: 
  pass

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 .

(不同的是，第一个也会捕获KeyboardInterrupt ， SystemExit和类似的东西，它们直接派生自exceptions.BaseException ，而不是exceptions.Exception 。)
