+1 as well.

I have a couple of suggestions for improving that implementation:

1. You're currently using os.urandom, which can raise a NotImplementedError. 
You should be prepared to fall back on a different PRNG... which leads to the
2nd suggestion:

2. random.randrange is a method on a default random.Random instance that,
although seeded by urandom (if available), may not be the user's preferred
PRNG.  I recommend making it possible for the user to supply their own
random.Random instance for use by the module.

That's all. :)
