What are some real-world examples of abstract classes in Python?

Abstract classes in Python are used to define a blueprint for other classes. For example, consider a 'Vehicle' class that defines methods like 'start' and 'stop', but doesn't implement them. Specific classes like 'Car' and 'Bike' would inherit from 'Vehicle' and provide their own implementations.

Can you give me more examples?

Sure! Another example is a 'Shape' class with an abstract method 'area'. Classes like 'Circle' and 'Rectangle' would inherit from 'Shape' and implement the 'area' method to calculate their respective areas.

Why would I use an abstract class instead of a regular class?

Using an abstract class enforces a contract for subclasses, ensuring they implement specific methods. This promotes code consistency and reusability.

Are there any built-in abstract classes in Python?

Yes, Python's 'abc' module provides the 'ABC' class and the 'abstractmethod' decorator to create abstract classes easily.
