Answer to Question #259636 in Python for Andy

Question

For those of you who may not now, a factorial is a product of multiplying from 1 until the number. Now, you must make a program that will accept an integer and then print out its factorial using loops.

Are you up for this task?

Instructions:

1. Input a positive integer.
2. Using a for() loop, generate the factorial value of the integer and print out the result.
3. Tip #1: Factorials work like this: Factorial of 5 = 1 * 2 * 3 * 4 * 5
4. Tip #2: There's a special case in factorials. The factorial of 0 is 1.

Input

A line containing an integer.

5

Output

A line containing an integer.

120

Answer 1

def factorial(n):
    if n == 0:
        return 1
    else:
        return n * factorial(n-1)
n=int(input("Input a number to compute the factiorial : "))
print(factorial(n))
