41. code in python. please use the same template in the picture
and provide code. thnx
# factorial function
def factorial(n):

if __name__ == '__main__':
start_num = int (input())
print('factorial({}) is {}'.format(start_num,
factorial(start_num)))
The factorial of 1 is written 1! and equals 1. Additionally, the factorial of 5 is written 5! and equals 5*4*3*2*1 = 120. Write a program to complete the factorial() function, which returns the calculated value for a factorial. Output wording should match examples below. Any negative input values should return "is not valid, factorial defined only for non- negative integer numbers.". For example, if the input is 5 the output is factorial (5) is 120 For example, if the input is -3 the output is factorial(-3) is not valid, factorial defined only for non-negative integer numbers.
