Umm yes, sort of. It depends on how you define some of those terms 
though. "mix them"???

I'm not sure what was wrong with equality?
Whether two types can be compared depends on whether the
comparison operators for those types work.
Its hard to tell in advance, that's why you should use
try/except to catch the errors (better to ask forgiveness
principle...)

That can play a part. But its not the only factor.

Not that I'm aware. Not even for the standard library.

As far as I can recall Pythonwin IDE under Windows has
a class browser that will show the heirarchy for any
given object. But I haven't used it in a long time,
I may be mistaken. Your IDE (Wing?) may have a similar
feature...
