What is Polymorphism? Polymorphism is a big, fancy word that means “many shapes.” Think about how you use your hands: you can use them to write, to eat, or to play games. Even though your hands are the same, they can do different things. This is similar to how polymorphism works in programming. In Python, polymorphism allows us to use a single function or method in different ways for different data types or classes. Real-World Example Imagine you have different pets: a dog, a cat, and a bird. They all have a method called speak, but they each make different Read More

Super() function for calling superclass methods

Hey there, young Python enthusiasts! Today, we’re diving into a super cool topic in Python programming called the super() function. Don’t worry if it sounds a bit tricky at first. By the end of this course, you’ll be a super super() expert! What is the Super() Function? Imagine you have a superhero, let’s call him “Superman.” Now, Superman is super strong, super fast, and super smart, right? But what if Superman also had a mentor who taught him everything he knows? That mentor is like a superclass, and Superman is like a subclass. The super() function helps our subclass (Superman) Read More

Method resolution order (MRO)

Hey there! Are you curious about how Python decides which method to run when you have classes and inheritance? Don’t worry if it sounds confusing, because today we’re going to learn all about it! We’ll talk about something called Method Resolution Order or MRO. But first, let’s break it down into simple pieces. What is a Method Resolution Order (MRO)? Imagine you have a family tree. In Python, classes and inheritance also form a kind of family tree. When you call a method on an object, Python needs to figure out which method to use if there are multiple methods Read More

Single inheritance vs. multiple inheritance

Hey there, future coding wizard! Today, we’re going to dive into the magical world of inheritance in Python. Imagine you have a treasure chest full of different kinds of toys, and you want to organize them neatly. Well, that’s what inheritance does with code! It helps us organize our code neatly by allowing one class to inherit attributes and methods from another. Now, let’s talk about two special types of inheritance: Single Inheritance and Multiple Inheritance. 1. Single Inheritance: Think of a single inheritance like a tree with branches. You have one main branch (the parent class), and from that Read More

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
