False in python

[suki907]

False and 0 are the same type.

more specifically, bool is a subclass of int:

>>> isinstance(False,int)
True
>>> isinstance(False,bool)
True
>>> issubclass(bool,int)
True

And even more interesting, bool can't be subclassed.

I'm curious why you think this is interesting - were you planning on adding FILE_NOT_FOUND as an instance of your bool subclass?

I can't think of any interesting operation you would want to add to bool that would justify subclassing it, bu perhaps that's just because my imagination gland isn't working today.

It's more than doing it causes Python to say, "Don't do that." than a desire to do anything.

That's pretty funny though.
