Mastering Python Design Patterns, Second Edition
This is the code repository for Mastering Python Design Patterns, Second Edition, published by Packt.
A guide to creating smart, efficient, and reusable software
What is this book about?
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 find sections on corrections, best practices, system architecture, and its designing aspects. This book covers the following exciting features:
- Explore Factory Method and Abstract Factory for object creation
- Clone objects using the Prototype pattern
- Make incompatible interfaces compatible using the Adapter pattern
- Secure an interface using the Proxy pattern
- Choose an algorithm dynamically using the Strategy pattern

Errata
- Chapter 9, Implementation of Proxy Pattern section: The code block following the sentence "Let's recapitulate the full code of the proxy.py file:" is incorrect. The correction can be found at https://github.com/PacktPublishing/Mastering-Python-Design-Patterns-Second-Edition/blob/master/ERRATUM-PYTHON-DESIGN-PATTERN-PROXY.pdf.
Instructions and Navigations
All of the code is organized into folders. For example, Chapter02.
The code will look like the following:
class Musician:
def __init__(self, name):
self.name = name
def __str__(self):
return f'the musician {self.name}'
def play(self):
return 'plays music'
Following is what you need for this book: This book is for intermediate Python developers. Prior knowledge of design patterns is not required to enjoy this book.
