Python Exercise: Calculate the factorial of a number

Python Functions: Exercise-5 with Solution

Write a Python function to calculate the factorial of a number (a non-negative integer). The function accepts the number as an argument.

Sample Solution:-

Python Code:

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))

Sample Output:

Input a number to compute the factiorial : 4
