I don’t know whether I like any of this <wink> but I think a more natural spelling would be: val = name.strip()[4:].upper() except (AttributeError, KeyError) as -1 which could devolve into: val = name.strip()[4:].upper() except KeyError as -1 or: val = name.strip()[4:].upper() except KeyError # Implicit `as None` I would *not* add any spelling for an explicit bare-except equivalent. You would have to write: val = name.strip()[4:].upper() except Exception as -1 Cheers, -Barry
