Or slightly better:

from operator import mul
def factorial(num):
return reduce(mul, range(2, num+1), 1)

[issue2138] Add a factorial function

2008-05-31 Thread Joshua Uziel 

Joshua Uziel <[EMAIL PROTECTED]> added the comment:

It's a simplified version, but why not something like this:

import operator
def factorial(num):
return reduce(operator.mul, range(1, num+1))

A product() function could also be done similarly.
