Overview of this book

This new edition of Expert Python Programming provides you with a thorough understanding of the process of building and maintaining Python apps. Complete with best practices, useful tools, and standards implemented by professional Python developers, this fourth edition has been extensively updated. Throughout this book, you’ll get acquainted with the latest Python improvements, syntax elements, and interesting tools to boost your development efficiency. The initial few chapters will allow experienced programmers coming from different languages to transition to the Python ecosystem. You will explore common software design patterns and various programming methodologies, such as event-driven programming, concurrency, and metaprogramming. You will also go through complex code examples and try to solve meaningful problems by bridging Python with C and C++, writing extensions that benefit from the strengths of multiple languages. Finally, you will understand the complete lifetime of any application after it goes live, including packaging and testing automation. By the end of this book, you will have gained actionable Python programming insights that will help you effectively solve challenging problems.

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.

With the example of Hy, we've seen that metaprogramming can even be used to implement other languages on top of the Python runtime. The road taken by Hy developers is of course quite unusual and, generally the best way to bridge Python with other languages is through custom Python interpreter extensions or using shared libraries and foreign function interfaces. And these are exactly the topics of the next chapter.
