1. Python Program for factorial of a number

Factorial of a number is products of all natural number to till that number.

for eg:

5!=5*4*3*2*1=120

100!=1*2*3*...........................................99*100

Logic: Suppose we have to find the the factorial of a number n then we required to multiply all number starting from 1 to n

n!=1*2*3*4*.........................(n-1)*n!

So we need to multiply all these numbers in this range 1 to n+1

why did I not  take range 1 to n because range function gives values less than 1 

OUTPUT:

Implementation using Loop
