This simple text-based To-Do List Manager is a practical Python project that demonstrates core programming concepts like loops, conditional logic, user input handling, and structured data storage. Its key features include adding task descriptions, viewing tasks with clear status indicators (Done/Not Done), updating task completion statuses, deleting unwanted tasks, and a user-friendly exit option. Common uses for this tool include personal daily task planning, serving as a beginner-friendly introduction to interactive CLI application development, and acting as a foundation for more advanced versions (such as adding persistent storage via files or a database, or a graphical interface) to meet larger productivity needs.
