Fredrik> if you study real python code, you'll find that there is.
I mean that the language doesn't prefer a single way, as opposed to programmers' conventions.
it's more than just a convention -- built-in functions and operators always return 0 for false and 1 for true whenever they need to in- vent a boolean value. this is documented in the language reference.
(and if you look inside, there's something called Py_False that's an integer zero, and something called Py_True that is an integer one).
this is also true for the standard library, and lots of major extensions.
also note that the PEP says "The bool type would be a straightforward subtype (in C) of the int type, and the values False and True would behave like 0 and 1 in most respects". Guido didn't pick those values out of thin air...
