Python Class
A class is a collection of objects. A class contains the blueprints or the prototype from which the objects are being created. It is a logical entity that contains some attributes and methods.
To understand the need for creating a class let’s consider an example, let’s say you wanted to track the number of dogs that may have different attributes like breed, and age. If a list is used, the first element could be the dog’s breed while the second element could represent its age. Let’s suppose there are 100 different dogs, then how would you know which element is supposed to be which? What if you wanted to add other properties to these dogs? This lacks organization and it’s the exact need for classes.
Some points on Python class:
- Classes are created by keyword class.
- Attributes are the variables that belong to a class.
- Attributes are always public and can be accessed using the dot (.) operator. Eg.: Myclass.Myattribute
Class Definition Syntax:
class ClassName:
# Statement-1
.
.
.
# Statement-N
Creating an Empty Class in Python
In the above example, we have created a class named Dog using the class keyword.
# Python3 program to
# demonstrate defining
# a class
class Dog:
pass
Python OOPs Concepts
Object Oriented Programming is a fundamental concept in Python, empowering developers to build modular, maintainable, and scalable applications. By understanding the core OOP principles—classes, objects, inheritance, encapsulation, polymorphism, and abstraction—programmers can leverage the full potential of Python’s OOP capabilities to design elegant and efficient solutions to complex problems.
