understanding recursion 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: recursion in python

def yourFunction(arg):
    #you can't just recurse over and over, 
    #you have to have an ending condition
    if arg == 0:
        yourFunction(arg - 1)
        
    return arg

Example 3: Recursion Python

students = {    'Alice': 98,    'Bob': 67,    'Chris': 85,    'David': 75,    'Ella': 54,    'Fiona': 35,    'Grace': 69}
