Getting method from within method?

[David M. Cooke]

I want to do recursion, like this:

def factorial(n):
    if n <= 1: return 1
    else return n * factorial(n-1)

However, this depends on the name of the method staying the same. For
instance, if I did this:

fact = factorial
factorial = None

fact(5) would give me an error since factorial isn't a method anymore.
It would be nice if there was some way of referring to the method
inside of the method.

Is there any way of doing this easily?
