Shopping List Application

Overview

This simple Python script allows users to create and manage a shopping list interactively. Through a series of commands, users can add items to the list, view the current list, or receive help on how to use the application. The script is designed to be user-friendly, providing clear prompts and feedback throughout the interaction.

The application operates in a command-line interface (CLI), making it a practical tool for quick modifications and updates to your shopping needs. Whether you're planning a grocery run or gathering supplies for a project, this shopping list app makes it easy to keep track of what you need.

Features

• Add Items: Allows users to add items to their shopping list.
• View List: Users can view all items currently on the list at any time.
• Interactive Help: Users can type 'HELP' to display helpful information about the available commands.

Commands

• DONE - Stops the input loop and displays the final list.
• HELP - Shows help information about the commands.
• SHOW - Displays all the items currently on the shopping list.
