Python Program to Find Factorial of Number using Recursion

The below code finds the factorial of a Number using Recursion. Initially, the input is taken from the user and the calls the recursive function which returns the factorial value of the given number.

# Python program to find the factorial of a number using recursion

# recursive function
def recur_factorial(n):  
   if n == 1:
       return n
   else:
       return n*recur_factorial(n-1)

# input
num = int(input("Enter number: "))

# check number is positive, negative, or zero
if num < 0:
   print('Factorial does not exist for negative numbers')
elif num == 0:
   print('The factorial of 0 is 1')
else:
    # function call
    print('The factorial of',num,'is', recur_factorial(num))

Output:

Enter number: 5
The factorial of 5 is 120
