🧠 Code Architecture Overview

🔹 Class: Task

Handles information related to a single task:

• task — title of the task

• priority — task priority level

• comment — optional description or notes

It also implements __str__() for clean text representation.

---

🔹 Class: ToDo

Responsible for the main application logic:

• Maintaining a list of Task objects

• Adding tasks

• Removing tasks by index

• Displaying tasks in a numbered list

• Saving tasks into a CSV file

This class keeps the program organized and easy to extend.
