Classes and Objects in Python

Python is an object-oriented programming language. This means that almost all the code is implemented using a special construct called classes. A class is a code template for creating objects.

Object-oriented programming is a paradigm centered around the concept of "objects"—self-contained units that combine data and behavior. OOP languages use classes to define the structure and behavior of these objects.

Core Concepts

Class – A blueprint for creating objects. It defines attributes (data) and methods (functions).
Object – An instance of a class. Each object can hold unique data and use shared behavior.
Encapsulation – Bundling data and methods that operate on that data within a single unit (class), and restricting direct access to some components.
Inheritance – A mechanism where one class can inherit properties and methods from another, promoting code reuse.
Polymorphism – The ability to use a single interface to represent different underlying forms (data types or classes).
Abstraction – Hiding complex implementation details and showing only the essential features of an object.

Constructors in Python: Learn How to create a constructor to initialize an object in Python. create different types of constructors.

Python Destructors to Destroy the Object: Learn to create a destructor in Python to release the other resources object were using.

Encapsulation in Python: Learn to implement Encapsulation in Python using class. implement Data Hiding using public, protected, and private members

Polymorphism in Python: Learn to implement Polymorphism in Python using function overloading, method overriding, and operator overloading.

Inheritance in Python: Learn to implement inheritance in Python. Also, learn types of inheritance and MRO (Method Resolution Order).

Python Instance Variables: Learn to create and access instance variables. Modify values of instance variables. Understand how dynamically we can add or delete instance variables from the object

Python Class Variables: Learn to create, modify and access class variables. Understand the difference between instance variables and class variables.

Python Class Method: Learn to create and call class methods. Create class method using the @classmethod decorator and classmethod()function
