Write a Python function to check whether a number is "Perfect" or not.According to Wikipedia : In number theory, a perfect number is a positive integer that is equal to the sum of its proper positive divisors, that is, the sum of its positive divisors excluding the number itself (also k...
In this tutorial we will see how can we check in Python if a given number is a perfect square or not without using the sqrt function in Python.
