This program iterating through each number one by one in the list, and check whether a given number is a perfect number or not. If a perfect number is found then print it else skip it. Here, thecheckPerfectNum()function is used to find its all positive divisors excluding that number...
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.
