Mastering Python Design Patterns - Second Edition

By: Kamon Ayeva, Sakis Kasampalis

Overview of this book

Python is an object-oriented scripting language that is used in a wide range of categories. In software engineering, a design pattern is an elected solution for solving software design problems. Although they have been around for a while, design patterns remain one of the top topics in software engineering, and are a ready source for software developers to solve the problems they face on a regular basis. This book takes you through a variety of design patterns and explains them with real-world examples. You will get to grips with low-level details and concepts that show you how to write Python code, without focusing on common solutions as enabled in Java and C++. You'll also fnd sections on corrections, best practices, system architecture, and its designing aspects. This book will help you learn the core concepts of design patterns and the way they can be used to resolve software design problems. You'll focus on most of the Gang of Four (GoF) design patterns, which are used to solve everyday problems, and take your skills to the next level with reactive and functional patterns that help you build resilient, scalable, and robust applications. By the end of the book, you'll be able to effciently address commonly faced problems and develop applications, and also be comfortable working on scalable and maintainable projects of any size.

The Bridge Pattern

In the previous two chapters, we covered our first structural pattern, adapter, which is used to make two incompatible interfaces compatible, and decorator, which allows us to add responsibilities to an object in a dynamic way. There are more similar patterns. Let's continue with the series!

A third structural pattern to look at is the bridge pattern. We can actually compare the bridge and the adapter patterns, looking at the way both work. While adapter is used later to make unrelated classes work together, as we saw in the implementation example we discussed in Chapter 4, The Adapter Pattern, the bridge pattern is designed up-front to decouple an implementation from its abstraction, as we are going to see.

In this chapter, we will discuss:

  • Real-world examples
  • Use cases
  • Implementation
