What is the ABC module in Python?

The ABC module in Python provides tools for defining abstract base classes, which help in creating a common interface.

How do I create an abstract class using the ABC module?

You can create an abstract class by inheriting from ABC and using the @abstractmethod decorator for abstract methods.

Can you give me an example of an abstract class?

Sure! Here's a simple example:

from abc import ABC, abstractmethod

class Animal(ABC):
    @abstractmethod
    def sound(self):
        pass

class Dog(Animal):
    def sound(self):
        return 'Woof!'

What are the benefits of using abstract base classes?

Abstract base classes help enforce a contract for subclasses, ensuring they implement specific methods, which promotes consistency.
