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.

Summary


We began the chapter by understanding Compound patterns and looked at the Model-View-Controller pattern and how it is effectively used in software architecture. We then looked at how the MVC pattern is used to ensure loose coupling and maintain a multilayer framework for independent task development.

You also learned the pattern with a UML diagram and sample code implementation in Python v3.5 along with the explanation. We also covered a section on FAQs that would help you get more ideas on the pattern and its possible advantages/disadvantages.

In the next chapter, we will talk about the Anti patterns. See you there!
