To have a general "catchall" clause, an empty except does the trick:
try: action() except NameError: ... # Handle NameError except IndexError: ... # Handle IndexError except: ... # Handle all other exceptions else: ... # Handle the no-exception case
The empty except clause is a sort of wildcard feature.
It catches everything.
The following catches everything without listing anything:
try: action() except: ... # Catch all possible exceptions
