Write a Python program to compute the factorial of a non-negative integern, denoted by n!, that is defined as the product of all positive integers less than or equal to n. For example, 3! - 6 5! - 120 In mathematics, the factorial of a non-negative integer n, denoted by n!, is the product of all positive integers less than or equal to n. For example, 5!= 5*4*3*2*1 The value of el is 1, according to the convention for an empty product. print('The program computes the factorial of a non-negative integer n,') print("denoted by n!, is the product of all positive integers less than or equal to n.') Inititalize number to zero. number = 0 # Get a valid number from the user. fill in the missing codes to compute factorial n! # Initialize the accumulator variable. fill in the missing codes to compute factorial n! # Calculate the factorial of the number fill in the missing codes to compute factorial ! # Display the factorial of the number fill in the missing codes to compute factorial ni
