What are some examples of using the ABC module in Python?

The ABC module in Python provides tools for defining abstract base classes. Would you like to see a specific example?

Yes, can you show me how to create 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!'

class Cat(Animal):
    def sound(self):
        return 'Meow!'

This defines an abstract class Animal with an abstract method sound.

How do I instantiate a class that inherits from an abstract class?

You can instantiate a subclass like this:

dog = Dog()
print(dog.sound())  # Output: Woof!

You cannot instantiate the Animal class directly.
