Submitted by razormist on Wednesday, December 11, 2024 - 23:37.

In this tutorial, we’ll learn how to program "How to Find the Sum of Even Factor Numbers in Python." The objective is to find the sum of even factors of a number based on the given input. A sample program will be provided to demonstrate the process of identifying and summing the even factors. So, let’s get started!

This topic is simple to understand. Just follow the instructions I provide, and you’ll be able to complete it with ease. The program I’ll demonstrate will show you the proper way to find the sum of the even factors of a number. I’ll also include a straightforward and efficient method to achieve this effectively. So, let’s start coding!

Getting Started:

First you will have to download & install the Python IDLE's, here's the link for the Integrated Development And Learning Environment for Python https://www.python.org/downloads/.

Creating Main Function

This is the main function of the application. The following code will display a simple GUI in terminal console that will display program. To do this, simply copy and paste these blocks of code into the IDLE text editor.

def evenfactorssum(n):
        s = 0
        for i in range(1, n+1):
                
                if n % i == 0:
                        
                        if i % 2 == 0:
                                
                                s = s+i
                
        return s
 
 
while True:
        print("\n================= Find Sum of Even Factors Numbers =================\n\n")
 
 
        n = int(input("Enter a number: "))
        
        print("Result: ", evenfactorssum(n))
 
        opt = input("\nDo you want to try again?(yes/no): ")
 
        if opt.lower() == 'yes':
                ret=False
        elif opt.lower() == 'no':
                ret=True
                print("Exiting program....")
        else:
                print("Please enter yes/no:")
                break
 
        if ret == False:
                continue

This program calculates the sum of all even factors of a given number \( n \). It does this by iterating through all integers from \( 1 \) to \( n \), checking if they are factors of \( n \) (i.e., \( n \% i == 0 \)), and further verifying if the factor is even (\( i \% 2 == 0 \)). If both conditions are satisfied, the factor is added to a running total. The program repeatedly asks the user if they want to try again until the user responds with "no" to exit.

Output:

There you have it we successfully created How to Find Sum of Even Factors Numbers in Python. I hope that this simple tutorial help you to what you are looking for. For more updates and tutorials just kindly visit this site. Enjoy Coding!
