Creating a ToDoList Using Python OOP: A Simple Approach
Are you learning Python and curious about object-oriented programming (OOP)? If so, you might find the task of creating a simple ToDoList quite engaging! This guide walks you through a straightforward implementation of a ToDoList in Python using OOP principles. Let's explore the problem and the solution step by step.
The Problem
You’ve been given the task to create a ToDoList that will contain a series of simple tasks. After defining the tasks, you want to mark certain tasks as done and print the list with their statuses. Your provided initial code has a good start, but there are some issues to resolve for optimal functionality.
Expected Output
Your goal is to achieve an output like this after running the code:

However, your current implementation is not delivering the expected output. Let's fix that!
The Solution
Understanding the Current Code
Class Definition:
You have a class ToDoList that should manage tasks.
You also have a Task class that represents individual tasks.
Core Components:
The ToDoList class should be able to store multiple tasks and print their status (done or undone).
The Task class needs to track the name of a task and whether it has been completed.
Optimizing the Code
The existing code can be transformed for better clarity and efficiency. The goal here is to refactor it so that it works as intended without unnecessary complexity.
Step 1: Defining the Task Class
Let's create a more refined version of the Task class. Instead of using a dictionary, we will keep track of tasks directly within the class:

Step 2: Updating the ToDoList Class
Now, let's update the ToDoList to work with a list of Task objects instead of a dictionary:

Step 3: Bringing It All Together
Now, let’s put everything together in a simple script that demonstrates how to use these classes:

Output Explanation
When you run the above code, your output should reflect the correct status of each task based on whether it's done or not:

Conclusion
By utilizing OOP principles in Python, creating a ToDoList becomes an excellent exercise to reinforce your programming skills. This simple yet effective solution uses classes to model both tasks and the to-do list, enabling easy task management and visibility.
As you continue your Python journey, remember that clear code structure not only makes your code easier to understand but also more maintainable in the long run. Happy coding!
