Extending classes and reusing code

Hey there future Python master! Today, we’re going to dive into a super cool topic called “Extending Classes and Reusing Code in Inheritance” using Python. Don’t let the big words scare you! We’ll break it down step by step and have a lot of fun along the way. What is Inheritance? Imagine you have a super awesome robot, and you want to make a new robot that’s similar but with a few extra tricks. Inheritance is like copying some of the cool abilities of the first robot into the new one, so you don’t have to build everything from scratch. Read More


Hey, kiddo! Today, we’re going to dive into something super cool called “Inheritance” in Python. Imagine you have a toy box full of different toys. Some are cars, some are dolls, and some are action figures. Now, each of these toys has something special about them, right? Like cars have wheels, dolls can talk, and action figures can move their arms and legs. In Python, we have something similar called classes. Classes are like blueprints for creating objects, just like how the blueprints of a toy tell the factory workers how to make it. And guess what? With inheritance, we Read More

Getter and setter methods

Hey there, young coder! Today, we’re diving into the world of getter and setter methods in Python. Don’t let the fancy names scare you; I’ll explain everything in a way that’s easy to understand. What are Getter and Setter Methods? Imagine you have a treasure chest (let’s call it gold). Now, you want to keep track of how much gold is in the chest and also make sure nobody takes too much or puts in fake gold. Getter and setter methods are like the guards of your treasure chest. They help you control who can see inside (get) and who Read More

Access specifiers: public, private, and protected

Access specifiers in Python are like the locks on different doors in a big house. They decide who can go where and do what. Imagine you’re in a house with three types of doors: Public, Private, and Protected. Each door has its own rules about who can use it. Let’s explore these doors and their rules in Python! 1. Public Access Specifier: Description: Public doors are like the main entrance of a house. Everyone can use them freely without any restrictions. In Python: In Python, when you create a variable or a method without specifying any access specifier, it becomes Read More


What is Encapsulation? Imagine you have a treasure chest. You don’t want just anyone to open it and take the treasures inside, right? So, you put a lock on it. The lock is like a shield, protecting the treasures from being accessed by just anyone. In programming, encapsulation is like putting a lock on your data. It’s a way to protect your data from being accessed or modified by code that shouldn’t be messing with it. How does Encapsulation Work? Encapsulation in Python is often achieved using classes and objects. Classes are like blueprints. They define what an object will Read More

Constructor and destructor methods

Hey there! 🌟 Today, we will dive into a super cool topic in Python called Constructor and Destructor Methods. Don’t let the fancy names scare you off! We’ll break it down step by step, and by the end, you’ll be a pro at understanding them. What are Constructor and Destructor Methods? Imagine you’re building a house with LEGO bricks. Before you start building, you need to decide what kind of house you want, right? Constructor methods are like the blueprint for your house. They help create an object when you’re working with classes in Python. Now, once your LEGO house Read More

Class variables and static methods

Welcome to our technical course on class variables and static methods in Python! In this course, we will delve into the concepts of class variables and static methods, which are fundamental aspects of object-oriented programming (OOP) in Python. We’ll break down these concepts in a simple and easy-to-understand manner, perfect for beginners and enthusiasts alike. 1. Understanding Class Variables: In Python, a class variable is a variable that is shared among all instances (objects) of a class. It is declared within the class but outside any method. Let’s take a look at an example: Here, wheels is a class variable. Read More

Instance variables and methods

In this course, we’ll dive into the exciting world of Python programming and explore the concepts of instance variables and methods. These are fundamental building blocks in Python that allow us to create dynamic and interactive programs. We’ll start from scratch, assuming no prior knowledge, and gradually build up our understanding through clear explanations, fun examples, and engaging practice questions. 1. Introduction to Objects: 2. Instance Variables: 3. Instance Methods: Practice Questions: By the end of this course, you will have a solid understanding of instance variables and methods in Python. You’ll be able to create your own classes, define Read More
