... (I've seen lots of code defining constants True and False or variations), what's missing is a standard way so everybody can do it the same way.
That's what drove C99 to standardize a bool type. Indeed, Python may be the only non-trivial C project I've worked on that didn't #define its own boolean gimmick for internal use. I'd like to note too that a Boolean concept is needed all over the place, despite that it's not an official type. It shows up in docstrings even now:
print hasattr.__doc__ hasattr(object, name) -> Boolean ...
import os print os.isatty.__doc__ isatty(fd) -> Boolean ...
That's not an exhaustive list, just a tease.
