[PATCH 9/9] python: raise a more specific error in Messages.print_messages

[Justus Winter]

Raising Exception is considered bad since the only way to catch
it is to do 'except Exception'. Raising a TypeError is more
appropriate.

Since the format parameter has already been validated, checking
it again is not necessary. Simplify this conditional.
