Expert Python Programming - Third Edition

By: Michał Jaworski, Tarek Ziadé

Overview of this book

Python is a dynamic programming language that's used in a wide range of domains thanks to its simple yet powerful nature. Although writing Python code is easy, making it readable, reusable, and easy to maintain is challenging. Complete with best practices, useful tools, and standards implemented by professional Python developers, the third edition of Expert Python Programming will help you overcome this challenge. The book will start by taking you through the new features in Python 3.7. You'll then learn the advanced components of Python syntax, in addition to understanding how to apply concepts of various programming paradigms, including object-oriented programming, functional programming, and event-driven programming. This book will also guide you through learning the naming best practices, writing your own distributable Python packages, and getting up to speed with automated ways to deploy your software on remote servers. You’ll discover how to create useful Python extensions with C, C++, Cython, and CFFI. Furthermore, studying about code management tools, writing clear documentation, and exploring test-driven development will help you write clean code. By the end of the book, you will have become an expert in writing efficient and maintainable Python code.

Summary

In this chapter, we've explored the vast topic of metaprogramming in Python. We've described the syntax features that favor the various metaprogramming patterns in detail. These are mainly decorators and metaclasses.

We've also taken a look at another important aspect of metaprogramming, dynamic code generation. We described it only briefly as it is too vast to fit into the limited size of this book. However, it should be a good starting point that gives you a quick summary of the possible options in that field.

The next chapter will offer you a moment of rest as we focus on the topic of good naming practices.
