recurssion python code example

Example 1: recuursion python

# Reccursion in python 
def recursive_method(n):
    if n == 1:
        return 1 
    else:
        return n * recursive_method(n-1)
    # 5 * factorial_recursive(4)
    # 5 * 4 * factorial_recursive(3)
    # 5 * 4 * 3 * factorial_recursive(2)
    # 5 * 4 * 3 * 2 * factorial_recursive(1)
    # 5 * 4 * 3 * 2 * 1 = 120
num = int(input('enter num '))
print(recursive_method(num))

Example 2: 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 3: python recursion example

# Recursive Factorial Example
# input: 5 
# output: 120 (5*4*3*2*1)
def factorial(x):
    if x == 1:
        return 1
    else:
        return (x * factorial(x-1))
