Missing interfaces in Python...

I think I see what you mean, but that's an odd way to put it.
Typically, you aren't going to handle the exceptions produced by type
errors. Of course, you want some way to test that your code doesn't
have type errors. Static type checking is one way of doing the
requisite testing, unit tests are another, but it's the tests that are
useful, not the interfaces per se. Adding interfaces to python, which
doesn't support static type checking, would be useless IMO.
