The number $n$ factorial is the product of the first $n$ positive integers. This number is denoted $n!$. For example,\[5! = 1 \cdot 2 \cdot 3 \cdot 4 \cdot 5 = 120.\] Write a Python program to compute $n!$, where the user enters any positive integer $n.$ Use your program to compute $16!$, and enter the value of $16!$ that it gives you in the box below.

From the program,

16! = 20922789888000

The python program is as follows:

n = int(input("Number: "))

if n < 0:

     print("Positive integers only")

else:

     result = 1

     for i in range(1,n+1):

           result = result * i

     print(n,"! = ",result)

Step-by-step explanation:

This line prompts user for input

n = int(input("Number: "))

This line checks if n is negative

if n < 0:

If yes, the following print statement is executed

     print("Positive integers only")

If otherwise, the factorial of the input number is calculated

else:

This line initial the result to 1

     result = 1

This line iterates from 1 to user input

     for i in range(1,n+1):

This line multiply the value of each iteration to get the factorial of the input number

           result = result * i

This line prints the factorial of the input number

     print(n,"! = ",result)

for the first question it would be the second answer for the second question it would be the third answer and for the third question it would be the first answer
