Key Functions

• fetch_tasks(): Retrieves all tasks from the MongoDB collection and stores them in a local list.

• add_task(description): Creates a new task document and inserts it into the database.

• view_tasks(): Prints the list of all current tasks to the console.

• update_task(task_number, new_task): Finds a task by its list number and updates its description in the database.

• delete_task(task_number): Deletes a specific task from the database.

• delete_all_tasks(): Removes all documents from the tasks collection.

Main Loop

The application runs in a while True loop, clearing the screen and displaying the updated task list after each action. It uses a match statement to handle user choices for creating, updating, or deleting tasks. Input validation is included to ensure the program runs smoothly.
