It depends on the __eq__ and __ne__ methods defined by the types. int
and str have their own implementations of "rich comparisons". But
that's a subject for another thread and another time, when you've
gotten deeper into implementing your own classes.

As I already said, you can't return an int from __bool__ in 3.x. In
2.x, __nonzero__ can return 0 for False and a "non-zero" int for True
-- but only an int (not long, float, etc).
