Factorial of a large number in python

Question

Here\'s my approach to factorials:

def factorial(n):
    \'\'\'Returns factorial of n\'\'\'
    r = 1
    for i in range(1, n + 1):
        r *= i
    return         


        

Answer 1

You do realize that factorial(100000) is aproximately 2.8242294080×10^456,573
That's why it's slow, it's huge.
