Here's the course outline for Object-Oriented Programming (OOP) in Python designed around project-based learning. Each lesson is structured to build on the previous one, focusing on core OOP concepts while gradually progressing through a project. The goal is for you to create a real-world Python application step by step. Course: Object-Oriented Programming (OOP) in Python Introduction to the Course: In this course, you'll learn how to develop Python applications using Object-Oriented Programming (OOP) concepts. You’ll build a Python project that evolves throughout the course, learning OOP concepts along the way. By the end, you’ll have a fully functional project that incorporates all the skills you've learned. Lesson 1: Introduction to OOP Concepts and Classes Goal: Learn the basics of OOP and how to create your first class. Introduction: OOP allows you to model real-world entities as objects. In this lesson, you will learn the basic concept of classes and objects. Key Concepts: Class: Blueprint for creating objects (instances). Object: An instance of a class. Attributes: Properties or data associated with an object. Methods: Functions associated with a class that define behavior. Project: Create a simple class, Person, with attributes like name and age, and a method that introduces the person. Hands-on Exercise: Create the Person class. Instantiate two objects of Person with different names and ages. Add a method called introduce that prints a sentence introducing the person. Quiz/Reflection Exercise: What is the difference between a class and an object? What is the purpose of methods in a class? Lesson 2: Constructors and the self Keyword Goal: Understand how to initialize objects and use the self keyword. Introduction: In OOP, constructors allow you to initialize an object's state when it is created. The self keyword is used to reference the current instance of the class. Key Concepts: Constructor (__init__): Special method that is called when an object is created. self keyword: Refers to the instance of the class, used to access variables and methods. Project: Modify the Person class to include a constructor that initializes the name and age attributes automatically when creating a new object. Hands-on Exercise: Add the __init__ method to the Person class. Test the class by creating new Person objects. Quiz/Reflection Exercise: Why is the self keyword necessary in Python classes? Can a constructor have multiple parameters? Lesson 3: Inheritance and Parent-Child Classes Goal: Learn how to extend classes using inheritance. Introduction: Inheritance allows a class to inherit attributes and methods from another class. This promotes code reuse. Key Concepts: Inheritance: A way to create a new class from an existing class, inheriting its attributes and methods. Parent Class: The class being inherited from. Child Class: The class that inherits from the parent class. Project: Create a Student class that inherits from the Person class, adding an additional attribute grade and a method to display the student's details. Hands-on Exercise: Add the Student class that inherits from Person. Create a Student object and display both the inherited and new attributes. Quiz/Reflection Exercise: How does inheritance help avoid redundancy in code? Can a child class override methods from the parent class? Lesson 4: Polymorphism and Method Overriding Goal: Learn how to override methods and create polymorphic behaviors. Introduction: Polymorphism allows you to define methods in a parent class and override them in a child class. This enables objects of different classes to be treated as objects of the parent class. Key Concepts: Method Overriding: Redefining a method in a child class. Polymorphism: The ability to use different classes through a common interface. Project: Override the introduce method in the Student class to include the student's grade. Hands-on Exercise: Override the introduce method in the Student class to include the student's grade. Create instances of both Person and Student and call the introduce method on both. Quiz/Reflection Exercise: What is the difference between method overloading and method overriding? Why might you want to override a method in a child class? Lesson 5: Encapsulation and Data Hiding Goal: Understand how to protect an object's state using private attributes and methods. Introduction: Encapsulation refers to bundling data and methods that operate on the data within one unit, and restricting access to some of the object's components. Key Concepts: Private Attributes/Methods: Use of underscores (_) to indicate that an attribute or method is private to the class. Getter/Setter Methods: Methods used to access or modify private attributes. Project: Modify the Person class to make the name and age attributes private and create getter and setter methods for them. Hands-on Exercise: Add getter and setter methods for name and age. Test the class by setting and getting the private attributes using the methods. Quiz/Reflection Exercise: Why is encapsulation important in OOP? How can you access private attributes if needed? Lesson 6: Advanced Project: Building a Simple Inventory System Goal: Apply all OOP concepts in building a project. Introduction: In this lesson, you'll integrate everything you've learned to build a small inventory system using classes, inheritance, polymorphism, and encapsulation. Project: Create an Item class with attributes like name, price, and quantity. Then, create Electronics and Clothing classes that inherit from Item. Add methods to calculate the total price and manage inventory. Hands-on Exercise: Create the Item, Electronics, and Clothing classes. Instantiate objects and manipulate inventory. Quiz/Reflection Exercise: How do you plan to improve or expand your inventory system? What is the most useful concept you’ve learned in this course so far? Lesson 7: Final Project and Reflection Goal: Complete the final project and reflect on the learning journey. Introduction: This is where you’ll apply everything you've learned to build a more complex system or project of your choice using the OOP concepts you’ve mastered. Project: Build a final project that involves multiple classes interacting with each other, using inheritance, polymorphism, and encapsulation. Hands-on Exercise: Build your final project, ensuring all concepts are incorporated. Test and refine your code. Quiz/Reflection Exercise: How did you apply OOP principles to your final project? What challenges did you face, and how did you overcome them? Once you’re ready, we can dive into Lesson 1! Just type “next lesson” or "next" to begin.
