Method overriding is a key feature of object-oriented programming (OOP) and inheritance. It allows a subclass (child class) to provide its own specific implementation of a method that is already defined in its superclass (parent class). When a method is called on an object of the child class, the child’s version of the method is…
Python does not support traditional method overloading in the way languages like C++ or Java do. If you define multiple methods with the same name, the last definition will simply overwrite all previous ones. However, you can achieve the same result—making a single method behave differently based on the number or type of arguments—using Python’s…
Python, Polymorphism allows us to use a single interface (like a function or a method) for objects of different types. Duck Typing is a specific style of polymorphism common in dynamically-typed languages like Python. What is Duck Typing? 🦆 The name comes from the saying: “If it walks like a duck and it quacks like…
Polymorphism is a core concept in OOP that means “many forms” 🐍. In Python, it allows objects of different classes to be treated as objects of a common superclass. This means you can use a single function or method to work with different data types, as long as they implement a specific action. 🌀 Polymorphism…
Data hiding in Python OOP is the concept of restricting access to the internal data of an object from outside the class. 🔐 It’s a way to prevent direct modification of data and protect the object’s integrity. This is typically achieved by using a naming convention that makes attributes “private” or “protected.” 🔒 How Data…
Rectangle Inheritance in OOP Python: Rectangle & Cuboid Example Inheritance in object-oriented programming (OOP) allows a new class (the child class) to inherit properties and methods from an existing class (the parent class). This is a powerful concept for code reusability ♻️ and establishing a logical “is-a” relationship between classes. For instance, a Cuboid is…
The primary use of a static method in Python classes is to define a function that logically belongs to the class but doesn’t need access to the instance’s data (like self) or the class’s state (like cls). They are essentially regular functions that are grouped within a class namespace. Key Characteristics and Use Cases General…
Class Variables Class variables are variables that are shared by all instances of a class. They are defined directly within the class but outside of any method. Unlike instance variables, which are unique to each object, a single copy of a class variable is shared among all objects of that class. They are useful for…
Instance Variables Instance variables are variables defined within a class but outside of any method. They are unique to each instance (object) of a class. This means that if you create multiple objects from the same class, each object will have its own separate copy of the instance variables. They are used to store the…
In Python classes, you can have different types of variables and methods, each with a specific scope and purpose. They are primarily categorized based on whether they belong to the class itself or to an object (instance) of the class. 1. Types of Variables Variables in a class are called attributes. a. Instance Variables 🧑💻…
