Have you ever wondered how many patterns there are in coding? It’s a fascinating question that often sparks curiosity among developers and software engineers. In this comprehensive guide, we will delve into the world of coding patterns and explore the different types and their significance. So, grab your favorite coding beverage and let’s dive in!

Quick Answer

There are currently roughly 26 different types of patterns for creating objects, structuring code, and solving common programming problems. These patterns provide developers with proven solutions and best practices that can be applied to various software development scenarios. By following coding patterns, you can make your code more readable, maintainable, and scalable.

Quick Tips and Facts

Coding patterns are reusable solutions to common programming problems.
Patterns can be categorized into three main types: creational, structural, and behavioral patterns.
Creational patterns focus on object creation mechanisms.
Structural patterns deal with object composition and relationships.
Behavioral patterns focus on communication between objects and the assignment of responsibilities.
Each pattern has its own unique characteristics, benefits, and drawbacks.
Understanding patterns can greatly enhance your coding skills and make you a more efficient developer.

Before we dive into the different types of coding patterns, let’s take a moment to understand what patterns are and why they are important in the world of software development.

Coding patterns are reusable solutions to common programming problems. They provide developers with a set of best practices and guidelines that can be applied to various scenarios. Patterns help in structuring code, improving code quality, and making it more maintainable and scalable.

Patterns can be categorized into three main types: creational, structural, and behavioral patterns. Creational patterns focus on object creation mechanisms, structural patterns deal with object composition and relationships, and behavioral patterns focus on communication between objects and the assignment of responsibilities.

Now that we have a basic understanding of coding patterns, let’s explore the different types in more detail.

1. Creational Patterns

Creational patterns are all about object creation. They provide ways to create objects while hiding the creation logic, making the code more flexible and decoupled. Here are some popular creational patterns:

Singleton Pattern

The Singleton pattern ensures that a class has only one instance and provides a global point of access to it. It is useful in scenarios where you want to limit the number of instances of a class, such as database connections or thread pools.

Factory Pattern

The Factory pattern provides an interface for creating objects, but allows subclasses to decide which class to instantiate. It is useful when you want to delegate the responsibility of object creation to subclasses.

Builder Pattern

The Builder pattern separates the construction of complex objects from their representation, allowing the same construction process to create different representations. It is useful when you want to create objects step by step or with different configurations.

2. Structural Patterns

Structural patterns focus on object composition and relationships. They help in building complex structures by providing mechanisms for object composition and inheritance. Here are some popular structural patterns:

Adapter Pattern

The Adapter pattern allows objects with incompatible interfaces to work together by creating a bridge between them. It is useful when you want to reuse existing classes that don’t have the desired interface.

Decorator Pattern

The Decorator pattern dynamically adds new behavior to an object by wrapping it in an object of a decorator class. It is useful when you want to add functionality to an object without modifying its structure.

Composite Pattern

The Composite pattern allows you to treat a group of objects as a single object. It is useful when you want to represent part-whole hierarchies and work with individual objects and groups of objects uniformly.

3. Behavioral Patterns

Behavioral patterns focus on communication between objects and the assignment of responsibilities. They help in defining how objects interact and distribute tasks among themselves. Here are some popular behavioral patterns:

Observer Pattern

The Observer pattern defines a one-to-many dependency between objects, so that when one object changes state, all its dependents are notified and updated automatically. It is useful when you want to establish a loosely coupled communication between objects.

Strategy Pattern

The Strategy pattern defines a family of algorithms, encapsulates each one, and makes them interchangeable. It is useful when you want to select an algorithm at runtime or provide different implementations of an algorithm.

Command Pattern

The Command pattern encapsulates a request as an object, thereby allowing you to parameterize clients with different requests, queue or log requests, and support undoable operations. It is useful when you want to decouple the sender of a request from the receiver.

Are there only 23 design patterns?

No, there are more than 23 design patterns. The famous “Gang of Four” book, “Design Patterns: Elements of Reusable Object-Oriented Software,” describes 23 design patterns. However, there are many other patterns beyond those described in the book. The 23 patterns mentioned in the book are just a subset of the patterns available.

What are patterns in code?

Patterns in code are reusable solutions to common programming problems. They provide developers with a set of best practices and guidelines that can be applied to various scenarios. Patterns help in structuring code, improving code quality, and making it more maintainable and scalable.

How many design patterns are there in Python?

Python, being a versatile programming language, supports various design patterns. While the number of design patterns specific to Python is not fixed, developers can apply the same design patterns used in other languages to Python as well. The 23 design patterns described in the “Gang of Four” book can be implemented in Python, along with other language-specific patterns.
