simpliest way to create a recursive function in python code example

Example 1: recursive function in python

def factorial(x):
    """This is a recursive function
    to find the factorial of an integer"""

    if x == 1:
        return 1
    else:
      	result = x * factorial(x-1)
        return ()


num = 3
print("The factorial of", num, "is", factorial(num))

Example 2: recursion python examples

# Recursive function factorial_recursion()

def factorial_recursion(n):  
   if n == 1:  
       return n  
   else:  
       return n*factorial_recursion(n-1)
