A class which contains one or more abstract methods is called an abstract class. First and foremost, you should understand the ABCMeta metaclass provided by the abstract base class. A Class is like an object constructor, or a "blueprint" for creating objects. This is a guide to Abstract Class in Python. The abstract class object can’t be directly created, but when we use this abstract class to provide certain functionalities to a base class or child class it can do that by creating the object of the base class. Abstract Classes in Python. class Rectangle(Shape): Abstract Factory defines an interface for creating all distinct products but leaves the actual product creation to … If we forget to implement one of the abstract methods, Python will throw an error. Abstract methods that are defined in the abstract class generally don’t have the body, but it is possible to have abstract methods with implementations in the abstract class and if any subclass is getting derived from such abstract class needs to provide the implementation for such methods.
