Prototype Design Pattern In Python from coursegalaxy.com
We are going to discuss some examples, use cases, and a possible implementation. Factory method is a creational design pattern that allows an interface or a class to create an object, but lets subclasses decide which class or object to instantiate. The abstract factory design pattern is a generalization of the factory method.

A factory method will receive information about a required object, instantiate it and return the object of the specified type. Therefore, this is my implementation of a typed abstract factory in python. In this article, i will try to highlight the usage of the pattern along with the difference with the factory pattern.

The point of the abstract factory pattern is to decouple the client (in this case petstore) from the concrete classes it creates (in this case dog). Abstract factory method is a creational design pattern that allows you to produce the families of related objects without specifying their concrete classes. An abstract factory is a generative design pattern that allows you.

Unified model language diagram for generic abstract factory in python. Creational design patterns are concerned with how objects are created. Therefore, the abstract factory pattern delegates the creation of objects to another class. I found it difficult to find cleanly typed python code that implemented the abstract factory creational design pattern. Abstract factory pattern implementation provides us with a framework.

So at runtime, the abstract factory is coupled with any desired concrete factory which can create objects of the desired type. The factory method design pattern is commonly used in libraries by allowing clients to choose what subclass or type of object to create through an abstract class. This pattern is best suited when one wishes to create multiple categories.
