How do I use the ABC module in Python?

The ABC module in Python provides tools for defining abstract base classes. You can use it to create a common interface for your classes.

Can you give me an example of 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!'

What happens if I try to instantiate the abstract class directly?

If you try to instantiate the abstract class directly, you'll get a TypeError. Abstract classes cannot be instantiated.

Can I have multiple abstract methods in one class?

Yes, you can define multiple abstract methods in a single abstract class. Each subclass must implement all of them.
