Learning Python Design Patterns - Second Edition - Second Edition

Overview of this book

With the increasing focus on optimized software architecture and design it is important that software architects think about optimizations in object creation, code structure, and interaction between objects at the architecture or design level. This makes sure that the cost of software maintenance is low and code can be easily reused or is adaptable to change. The key to this is reusability and low maintenance in design patterns. Building on the success of the previous edition, Learning Python Design Patterns, Second Edition will help you implement real-world scenarios with Python’s latest release, Python v3.5. We start by introducing design patterns from the Python perspective. As you progress through the book, you will learn about Singleton patterns, Factory patterns, and Façade patterns in detail. After this, we’ll look at how to control object access with proxy patterns. It also covers observer patterns, command patterns, and compound patterns. By the end of the book, you will have enhanced your professional abilities in software architecture, design, and development.

Frequently asked questions


Q1. Isn't MVC a pattern? Why is it called a Compound pattern?

A: Compound patterns are essentially groups of patterns put together to solve large design problems in software application development. The MVC pattern is the most popular and widely used Compound pattern. As it is so widely used and reliable, it is treated as a pattern itself.

Q2. Is MVC used only in websites?

A: No, a website is the best example to describe MVC. However, MVC can be used in multiple areas such as GUI applications or any other place where you need loose coupling and splitting of components in an independent way. Typical examples of MVC include blogs, movie database applications, and video streaming web apps. While MVC is useful in many places, it's overkill if you use it for the landing pages, marketing content, or quick single-page applications.

Q3. Can multiple views work with multiple models?

A: Yes, often you'd end up in a situation where the data needs to be collated from multiple models...
