We can run a try-except block without handling the exception the following ways:
try: 1/0 except: pass
try: 1/0 except Exception: pass
In the first case, using bare except: is like using except BaseException: which will also catch KeyboardInterrupt, SystemExit and errors like that, which are derived directly from exceptions.BaseException, not exceptions.Exception.
In second case, the things mentioned above won't be caught. The pass statement makes it possible to ignore the exceptions.
