Factorial in Python

 # This is Iterative method

# def factorial(n):

#     f = 1

#     for i in range(n):

#         f = f * (i+1)

#     return f

# a = int(input("Enter the no: "))

# print(factorial(a))

# This s recursion method

def factorial(n):

    if n==1:

        return 1

    else:

        return n*factorial(n-1)

a = int(input("Enter the no: "))

print(factorial(a))
