Great!

 >>>
def my_function(min, max=None):
     if max is None:
         max, min = min, 0
     return max - min
 >>> my_function(3, 7)
4

I meant that the order "min, max" is more intuitive than "max, min". 
Don't you agree? And it's the order used in random.randint(), 
random.randrange(), and random.uniform(), for examples.

Anyway, thanks, Michael.
