Question

Using python
Problem 7 (10 points). Given a number n calculate n! using a while loop. n!, called n factorial, is defined as the product of numbers 1 through n. For example 4! = 1 X 2 X 3 X 4 = 24 For example 2! = 1 X 2 = 2 For example 5! = 1 X 2 X 3 X 4 X 5 = 120 Sample program output: Please enter n: 3 3 factorial is 6

Explanation / Answer

Answer:

def factorial():
n = input ('Please enter n:')
input=1
i=1
while (i<=n):
input=input*i
i=i+1
print(' %d factorial is %d' %(n,input))

Output:

Please enter n: 5

5 factorial is 120
