Write a Python program that takes a number and tells if it is a perfect number or not. The input number has to be an INTEGER]
Perfect Number: An integer number is said to be a perfect number if its factors, including 1 but not the number itself, sum to the number.
=====
========
Example01:
Input:
6
Output:
6 is a perfect number
Explanation:
6 have 4 divisors: 1, 2, 3, and 6.
If we add all factors except itself, 6 = 1+ 2 + 3.
============ =======
=====E===== ==
Example02:
Input:
28
Output:
28 is a perfect number
Explanation:
28 have 6 divisors: 1, 2, 4, 7, 14, and 28.
If we add all factors except itself, 28 = 1+ 2 + 4 + 7+ 14.
