Understanding python abstract base classes

abstract base classes (abcs) in python are classes that are designed to be subclassed, but not instantiated directly. they provide a way to define a common interface for a group of classes, ensuring that all subclasses implement certain methods.

to work with abstract base classes in python, you need to import the `abc` class and the `abstractmethod` decorator from the `abc` module.

the `abc` class is used as a base class for defining your own abstract base classes, and the `abstractmethod` decorator is used to mark methods as abstract, indicating that they must be implemented by concrete subclasses.

here is a step-by-step tutorial on how to use abstract base classes in python:

1. import the necessary modules:

2. define your abstract base class by subclassing `abc`:

in this example, we define an abstract base class `shape` with two abstract methods: `area()` and `perimeter()`. any subclass of `shape` must implement these methods.

3. create concrete subclasses that inherit from the abstract base class:

here, we define two concrete subclasses `circle` and `square` that inherit from the abstract base class `shape`. both subclasses implement the abstract methods `area()` and `perimeter()`.

4. instantiate objects of the concrete subclasses and call their methods:

output:

by following this tutorial, you can create your own abstract base classes in python and ensure that subclasses adhere to a common interface. this helps in making your code more organized, maintainable, and less error-prone.
