Enhanced Command-Line To-Do List Application

This is an interactive to-do list application built purely in Python, designed to run in your command line or terminal. It offers standard task management features but includes a unique visual flair for completed items, making it easy to distinguish your progress.

This project is great for beginners to understand core Python concepts like lists, dictionaries, loops, conditional statements, and user input/output in a practical, fun way.

✨ Features

• Add Task: Easily add new to-do items to your list.
• View Tasks: Display all current tasks with their corresponding numbers and completion status.
• Mark Task as Complete: Mark a task as done by its number. Completed tasks are visually "crossed out" with a distinct hyphenated format (e.g., ---W-O-R-K-----) and marked with [X].
• Delete Task: Remove a task from the list using its number.
• User-Friendly Interface: Simple numbered menu for easy navigation.
• In-Memory Storage: Tasks are stored as long as the application is running (they are cleared when the program exits).

📊 How Completed Tasks Look

When you mark a task like "Work" as complete, it will transform from [ ] Work to something like:

[X] ---W-O-R-K-----

This provides a clear and unique visual indicator of completion.

🚀 How to Use

To run this To-Do List application, you'll need Python installed on your computer.

Prerequisites

• Python 3.x (Ensure you have a recent version of Python 3 installed.)

Running the Application

1. Save the code:

   • Save the Python code for the To-Do List into a file named todo_list.py.
   • Place this file in a convenient folder on your computer (e.g., Documents/PythonProjects/todo-app).

2. Open your Command Prompt / Terminal:

   • On Windows: Navigate to the folder where you saved todo_list.py in File Explorer. Click on the address bar at the top, type cmd, and press Enter.
   • On Mac/Linux: Open your Terminal application. Use the cd command to navigate to the directory where your todo_list.py file is located. For example: cd ~/Documents/PythonProjects/todo-app.

3. Execute the Python script:

   • Once you are in the correct directory in your Command Prompt/Terminal, type the following command and press Enter:

     python todo_list.py

4. Interact with the To-Do List:

   • The application will start, display a menu, and prompt you for a choice.
   • Type the number corresponding to the action you want to perform (e.g., 1 to add a task, 2 to view tasks).
   • Follow the on-screen instructions.
   • To exit the application, type 5 and press Enter.

🧠 Concepts Demonstrated

• list data structure for storing multiple tasks.
• dictionary data structure for storing task details (description and completion status).
• while loops for continuous program execution.
• if/elif/else for menu navigation and conditional logic.
• input() for user interaction.
• print() for displaying information.
• String methods (.strip(), .upper(), .join()) for text manipulation and formatting.
• Basic error handling (try-except for number input, if statements for valid choices/numbers).
• Functions (def) for organizing code into reusable blocks.
