What are abstract methods in Python?

What are abstract methods in Python?

Abstract methods are methods that are declared but contain no implementation. They are defined in abstract classes.

How do I create an abstract class in Python?

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

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 'Bark'

What happens if I don't implement the abstract method?

If you don't implement the abstract method in a subclass, you'll get a TypeError when you try to instantiate that subclass.
