I am so far unable to find the information I want about the Exception
class. Information like the signature of __init__ seems to be
unavailable. Any suggestions where I might find such information?

Officially, anyway.
This simply isn't true.

As an alternative to Python, I'd suggest REALbasic. Its main
disadvantage is that it is not free. But you get a language, editor,

Unless, of course, you want to switch off such checking at runtime, as
you might when using a design-by-contract approach.
