In C, ints are used for truth values. In python, any object can be used as a In C, ints are used for truth values. In python, any object can be used as a

:ctype:`bint` as well. This allows one to avoid having to wrap things in :c:type:`bint` as well. This reduces the need for wrapping things in
:func:`bool()`. For example, one can write:: :func:`bool()`. For example, one can write::
def is_equal(x): def is_equal(x):
return x == y return x == y
