IT Structure Design with Python Patterns

Design patterns are an important part of software development. They provide a standard, repeatable solution to encountered problems in system programming. Design patterns help programmers understand concepts, teach, learn, and build on other working ideas and concepts.

Design patterns are being used more and more in coding technology. Knowing object-oriented programming, inheritance, and polymorphism basics give a significant advantage. The following common types of Python patterns are distinguished.

Creational Python Design Patterns

This type provides information about IT structure design, a class, or object instance. Class creational patterns and object creational patterns are the main categories of object creational patterns. While class creational patterns make good use of inheritance in the instantiation process, object creational patterns use delegation to do the job.

factory method;
abstract factory;
singleton;
builder;
prototype;
object pool.

Structural Design Patterns

They organize different classes and objects, form larger structures and provide new features while keeping them flexible and efficient. They use inheritance to compose all interfaces and define the relationships that simplify the data structure.

decorator;
proxy;
adaptor;
composite;
bridge;
facade;
flyweight.

Behavioral Patterns

Behavioral patterns are associated with identifying common communication patterns between objects and implementing these patterns. They are related to algorithms and the responsibilities distribution between objects.

observer;
visitor;
iterator;
strategy;
command;
mediator;
memento;
state;
chain of responsibility.

Benefits of Using Design Patterns

Reusability

Patterns help to make code reusable across multiple projects through inheritance.

Transparency

Improves code transparency for all developers who will use it in the future.

Established solution

Solutions offered by design patterns are well proven and validated at critical stages.

Improved communication

Design patterns make communication between designers more efficient. When discussing IT structure design, software developers can imagine the high-level design when referring to the pattern name used to solve a particular problem.
