Simple Factory
Article Introduction：What is Simple Factory?
Simple factory is not design pattern. It simply decouples object creation from client code. In other words, Simple factory encapsulates object instantiation by moving instantiation logic to a separate class.

Polymorphism Types vs Design pattern
Article Introduction：How to use polymorphism and design patterns in combination? The combination of polymorphism and design patterns can enhance the flexibility and maintainability of the code by: 1. The policy pattern uses polymorphism to define the algorithm family, making it interchangeable at runtime; 2. The template method pattern delays the implementation of algorithm steps in the subclass through polymorphism; 3. The visitor pattern uses polymorphism in the form of double-scheduling, allowing new operations to be added in the class hierarchy.

PHP Master | The Null Object Pattern - Polymorphism in Domain Models
Article Introduction：Core points
The empty object pattern is a design pattern that uses polymorphism to reduce conditional code, making the code more concise and easy to maintain. It provides a non-functional object that can replace the real object, thus eliminating the need for null value checks.
Empty object mode can be used in conjunction with other design modes, such as factory mode creating and returning empty objects, or policy mode changing the behavior of an object at runtime.
The potential disadvantage of the empty object pattern is that it may lead to the creation of unnecessary objects and increase memory usage. It may also make the code more complicated because additional classes and interfaces are required.
To implement the empty object pattern, you need to create an empty object class that implements the same interface as the real object. This empty object provides a default implementation for all methods in the interface, allowing it to replace the real object. This makes

How to implement factory model in Python?
Article Introduction：Implementing factory pattern in Python can create different types of objects by creating a unified interface. The specific steps are as follows: 1. Define a basic class and multiple inheritance classes, such as Vehicle, Car, Plane and Train. 2. Create a factory class VehicleFactory and use the create_vehicle method to return the corresponding object instance according to the type parameter. 3. Instantiate the object through the factory class, such as my_car=factory.create_vehicle("car","Tesla"). This pattern improves the scalability and maintainability of the code, but it needs to be paid attention to its complexity
