no-or-in-except

Collection: fixit-extra Autofix: No Python: Any

Require tuples instead of or-expressions when catching multiple exception types.

Message

Avoid using ‘or’ in an except block. For example:’except ValueError or TypeError’ only catches ‘ValueError’. Instead, use parentheses, ‘except (ValueError, TypeError)’
