Python for Beginners [8.3] BUILD Your First Class STEP BY STEP! [LAB]

LAB: Create Your First Class in Python (OOP Fundamentals).
Python OOP Tutorial: Creating Your First Class, Constructors, Getters & Setters Explained.
Python OOP Hands-On Lab: Build a Customer Class with Getters & Setters.

Enough theory! Let's code. In this hands-on Python lab, we will build a Customer class from scratch, step-by-step.

We'll write the __init__ constructor, create private attributes, and build getter and setter methods to interact with our object's data safely. This is practical OOP that you will use in real projects.

In this video, you'll:
👨‍💻 Code a complete Python Class together.
🔐 Learn the purpose of private attributes (using __).
📖 Build Getter methods to safely access data.
✏️ Build Setter methods to safely modify data.
🛠️ Create multiple Object instances from our single Class.
❌ See what happens when you try to access private data directly (and why it fails!).

Follow along and code with me!

Learn Object-Oriented Programming (OOP) in Python step by step! 🚀
In this lab activity, we’ll create our first class in Python, explore constructors (__init__), understand private vs. public attributes, and implement getter & setter methods. You’ll also see how to create and modify objects from your classes, with real-world OOP applications.

🔑 What you’ll learn in this video:
- Python class syntax & naming conventions
- How to use the constructor (__init__)
- Defining private vs. public attributes
- Creating getter (accessor) & setter (mutator) methods
- Instantiating objects from classes
- Real-world OOP examples & applications

👉 By the end, you’ll understand how to build reusable, modular, and secure Python classes!

Ready to put theory into practice? 👩‍💻 In this hands-on lab, we'll walk through creating your very first class in Python. You'll learn the essential syntax, including how to define a constructor ($__init__$), set up attributes and methods, and use getters and setters to control access to your data. By the end, you'll know how to create multiple objects from a single class blueprint and understand the real-world benefits of OOP.

In this video, we cover:
- The Syntax of a Class: class keyword & naming conventions
- Creating a Constructor with __init__
- How to Use Getters (Accessors) and Setters (Mutators)
- The difference between public & private attributes (self.name vs self.__name)
- LAB ACTIVITY: Creating Objects from Your Class
- Real-World OOP Examples & Applications
