Write a python program to find the factorial of a number using recursion

In this source code example, we will write a python program to find the factorial of a number using recursion.

Write a python program to find the factorial of a number using recursion

ef recur_factorial(n):
 """Function to return the factorial
 of a number using recursion"""
 if n == 1:
    return n
 else:
     return n*recur_factorial(n-1)
# Change this value for a different result
num = 7
# uncomment to take input from the user
#num = int(input("Enter a number: "))
# check is the number is negative
if num < 0:
    print("Sorry, factorial does not exist for negative numbers")
elif num == 0:
    print("The factorial of 0 is 1")
else:
    print("The factorial of",num,"is",recur_factorial(num))

Output:

The factorial of 7 is 5040
