Mastering Python Design Patterns

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.

Summary


In this chapter, we covered three other structural design patterns: flyweight, MVC, and proxy.

We can use flyweight when we want to improve the memory usage and possibly the performance of our application. This is quite important in all systems with limited resources (think of embedded systems), and systems that focus on performance, such as graphics software and electronic games.

In general, we use flyweight when an application needs to create a large number of computationally expensive objects that share many properties. The important point is to separate the immutable (shared) properties from the mutable. We implemented a tree renderer that supports three different tree families. By providing the mutable age and x, y properties explicitly to the render() method, we managed to create only three different objects instead of eighteen. Although that might not seem like a big win, imagine if the trees were 2,000 instead of 18.

MVC is a very important design pattern used to structure an...
