Abstraction with ABC
Use the abc module to define abstract base classes and abstract methods.

Python Abstraction with ABC Program
This program helps you to learn the fundamental structure and syntax of Python programming.
# Program to demonstrate abstraction with ABC
from abc import ABC, abstractmethod
class Shape(ABC):
@abstractmethod
def area(self):
pass
class Circle(Shape):
def __init__(self, radius):
self.radius = radius
def area(self):
return 3.14 * self.radius * self.radius
c = Circle(5)
print("Area:", c.area())Output
Area: 78.5
Understanding Abstraction with ABC
Shape defines an abstract method 'area'; Circle provides a concrete implementation, enforcing a common interface.
Note: To write and run Python programs, you need to set up the local environment on your computer. Refer to the complete article Setting up Python Development Environment. If you do not want to set up the local environment on your computer, you can also use online IDE to write and run your Python programs.
