Jul 25, 2024 · Learn all the details about abstract classes in Python here, with suitable examples. The Python abstract class is allows you to create a set of methods that must be created within any child classes built from the abstract class.
Basically, you define __metaclass__ = abc.ABCMeta on the class, then decorate each abstract method with @abc.abstractmethod. Classes derived from this class cannot then be instantiated unless all abstract methods have been overridden.
In object-oriented programming, an abstract class is a class that cannot be instantiated. However, you can create classes that inherit from an abstract class. Typically, you use an abstract class to create a blueprint for other classes. Similarly, an abstract method is an method without an implementation.
