Title: Python Tutorial: Checking Perfect Numbers Using a While Loop
Introduction:
In this tutorial, we will explore how to create a Python program to check whether a given number is a perfect number. A perfect number is a positive integer that is equal to the sum of its proper divisors, excluding itself. We'll use a while loop to efficiently iterate through the divisors.
Let's get started with the code:
Explanation:
The is_perfect_number function takes an integer number as input and returns True if it is a perfect number, and False otherwise.
We initialize the sum_of_divisors variable to 1 because every number is divisible by 1.
Using a while loop, we iterate through potential divisors starting from 2 up to number // 2. We check if number is divisible by the current divisor. If it is, we add the divisor to the sum_of_divisors.
Finally, we check if the sum of divisors is equal to the original number and return the result.
In the main program, we take user input for a positive integer and call the is_perfect_number function to determine if it's a perfect number. The result is then printed to the user.
Now you can run this Python program to check whether a given number is a perfect number or not using a while loop.
