What are interfaces in Python and how do I use them?

In Python, interfaces are a way to define a contract for classes. They specify methods that must be implemented.

Can you give me an example of how to create an interface?

Sure! You can use the abc module to create an interface. Here's a simple example:

from abc import ABC, abstractmethod

class MyInterface(ABC):
    @abstractmethod
    def my_method(self):
        pass

How do I implement this interface in a class?

You can implement the interface by creating a class that inherits from it and defines the abstract method:

class MyClass(MyInterface):
    def my_method(self):
        print('Method implemented!')

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

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