Submitted by razormist on Thursday, November 27, 2025 - 21:32.

In this tutorial, we will learn how to program "How to Append, Delete, and Display Elements of a List Using Classes in Python". The objective is to manage the elements of a list by appending, deleting, and displaying them using Python classes. By the end of this tutorial, you will have a solid understanding of how to manipulate elements in a list effectively, helping you strengthen your problem-solving abilities and improve your coding skills.

This topic is straightforward and easy to understand. Simply follow the instructions provided, and you will complete it with ease. The program will guide you step by step through the process of manipulating elements in a list. So, let’s dive into the coding process!

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.

class check():
    def __init__(self):
        self.n = []
 
    def add(self, a):
        self.n.append(a)
 
    def remove(self, b):
        if b in self.n:
            self.n.remove(b)
        else:
            print("Value not found in list!")
 
    def dis(self):
        return self.n
 
 
while True:
    print("\n========= Append, Delete, and Display Elements of a List Using Classes =========\n")
 
    obj = check()
 
    choice = 1
    while choice != 0:
        print("0. Exit")
        print("1. Add")
        print("2. Delete")
        print("3. Display")
 
        choice = int(input("Enter choice: "))
 
        if choice == 1:
            n = int(input("Enter number to append: "))
            obj.add(n)
            print("List:", obj.dis())
 
        elif choice == 2:
            n = int(input("Enter number to remove: "))
            obj.remove(n)
            print("List:", obj.dis())
 
        elif choice == 3:
            print("List:", obj.dis())
 
        elif choice == 0:
            print("Exiting menu...")
 
        else:
            print("Invalid choice!!")
 
    print()
 
    opt = input("\nDo you want to try again? (yes/no): ").strip().lower()
    if opt == 'no':
        print("Exiting program...")
        break
    elif opt != 'yes':
        print("Invalid choice. Exiting program...")
        break

This Python program demonstrates list management using a class. It defines a `check` class with methods to add elements to a list, remove elements, and display the current list. Through a menu-driven interface, the user can repeatedly append, delete, or view list elements. The program also allows the user to exit the menu or repeat the entire process.

Output:

There you have it we successfully created How to Append, Delete, and Display Elements of a List Using Classes 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!
