In Python, abstraction can be achieved by using abstract classes and interfaces . A class that consists of one or more abstract method is called the abstract class. Abstract methods do not contain their implementation.

Use the abc module to create abstract classes . Use the abstractmethod decorator to declare a method abstract, and declare a class abstract using one of three ways, depending upon your Python version.30 Kas 2012

Python doesn’t directly support abstract classes . But it does offer a module that allows you to define abstract classes. To define an abstract class, you use the abc (abstract base class) module. The abc module provides you with the infrastructure for defining abstract base classes.

Its purpose is to define how other classes should look like, i.e. what methods and properties they are expected to have . The methods and properties defined (but not implemented) in an abstract class are called abstract methods and abstract properties.16 Eki 2021
