Python - Compute the factorial of N with recursion (among others)

# Calculating the factorial of a number 
# is a good way to practice recursion. Below 
# are examples of both recursive and iterative 
# approaches to calculating a factorial. Of course 
# python has its own builtin math module that 
# can also take care of factorials.

# factorial of N 
def recursiveFactorial(n):
    if n == 1:
        return n

# Iterative calculation of the factorial 
# of N 
def iterativeFactorial(n):
    result = 1
    while n > 1:
        result *= n
        n = n-1
    return result
