What are classes and interfaces in Python?

Can you explain what classes and interfaces are in Python?

Sure! In Python, a class is a blueprint for creating objects, defining properties and behaviors. An interface, on the other hand, is a way to define a contract for classes without implementing the methods.

How do I create a class in Python?

You can create a class using the class keyword followed by the class name. For example:

class MyClass:
    def __init__(self, value):
        self.value = value

What is the difference between a class and an interface?

A class can provide both implementation and state, while an interface only defines methods that must be implemented by a class, without providing any implementation itself.

Can you give an example of an interface in Python?

Python doesn't have a formal interface keyword, but you can use abstract base classes (ABCs) from the abc module to create interfaces. Here's a simple example:

from abc import ABC, abstractmethod

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