Abstraction is one of the core principles of Object-Oriented Programming (OOP).<\/p>\n\n\n\n
Abstraction means hiding internal implementation details and showing only the essential features to the user<\/strong>.<\/p>\n\n\n\n In simple words: When you drive a car:<\/p>\n\n\n\n That is abstraction.<\/p>\n\n\n\n Python provides abstraction using:<\/p>\n\n\n\n To create an abstract class, we use the If you try:<\/p>\n\n\n\n It will give an error.<\/p>\n\n\n\n Encapsulation Abstraction Abstraction simplifies complex systems by hiding implementation details and exposing only what is necessary.<\/p>\n\n\n\n It helps create clean, secure, and scalable OOP programs.<\/p>\n\n\n
Abstraction focuses on what an object does, not how it does it.<\/p>\n\n\n\nReal-Life Example<\/strong><\/h2>\n\n\n\n

from abc import ABC, abstractmethodclass Shape(ABC): @abstractmethod
def area(self):
passclass Circle(Shape): def __init__(self, radius):
self.radius = radius def area(self):

Shape<\/code> is an abstract class<\/li>\n\n\n\narea()<\/code> is an abstract method<\/li>\n\n\n\nCircle<\/code> must implement the area()<\/code> method<\/li>\n\n\n\nShape<\/code> directly<\/li>\n<\/ul>\n\n\n\ns = Shape()<\/pre>\n\n\n\n

Hides data
Focuses on restricting access<\/p>\n\n\n\n
Hides implementation
Focuses on showing only essential behavior<\/p>\n\n\n\nKey Takeaway<\/strong><\/h2>\n\n\n\n
