If you have ever bought any programming books, you might have noticed that there are two types of them: books that are too short to understand the topic and books that are too long making it inevitable that you get bored. We've tried hard to avoid both of these categories with Design Patterns Explained Simply.
This book is fast and simple way to get the idea behind each of the 29 popular design patterns. The book is not tied to any specific programming language and will be good for you as long as you have a basic knowledge of OOP.
Most chapters are available on the website, so you can check out the simplicity of the language in the book and the way materials are presented.
Why should I read this book?
It's simple. It's written in clear and simple language that makes it easy to read and understand.
It's short. Yes, there are no useless demos or huge code listings — just clear and easy-to-understand descriptions with many graphical examples.
When you finish reading this book, you'll have good reason to go to your boss and ask him for apromotion. Why? Because using design patterns will allow you to get your tasks done twice as fast, to write better code and to create efficient and reliable software architecture.
How do I become a programming ninja?
The main difference between a ninja and a novice is the knowledge of secret coding tricks, as well as the awareness of most pitfalls and the ability to avoid them.
Design patterns were created as a bible for avoiding problems related to software design. Doesn’t that make it a true ninja’s handbook?

Understand the structural, creational, and behavioral Python design patterns
Get to know the context and application of design patterns to solve real-world problems in software architecture, design, and application development
Get practical exposure through sample implementations in Python v3.5 for the design patterns featured
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 Facade 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.
