Grocery List App

This Python project implements a simple grocery list application where users can add, remove, list, and exit items from their grocery list.

How to Use​

  1. Run the Python script.
  2. Follow the on-screen instructions to perform various actions:
    • Enter 1 to add an item.
    • Enter 2 to remove an item.
    • Enter 3 to list all items.
    • Enter 0 to exit the program.

Functionalities​

Welcome Message​

Upon starting the program, users are greeted with a welcome message and instructions on how to use the application.

Add Item​

Users can add items to their grocery list by entering the item name when prompted.

Remove Item​

Users can remove items from their grocery list by entering the name of the item they wish to remove when prompted.

List Items​

Users can view all the items currently on their grocery list.

Valid Option Check​

The program checks whether the user input is a valid option and prompts the user to enter a valid option if necessary.

Exit Program​

Users can exit the program at any time by entering 0.

Bugs and Enhancements​

  • Currently, if the user tries to add an item without entering anything, it will add an empty string as an item. This behavior needs to be fixed.
  • Optionally, users can enhance the program by adding a fourth option that allows them to modify an existing list item.

Additional Notes​

  • The program handles cases where users try to remove an item that does not exist in the grocery list.
  • Enumerate is used to display items in the list starting from 1 instead of 0 for better user understanding.
  • This project serves as a simple exercise to practice Python programming skills.
