Expert Python Programming - Fourth Edition

By: Michał Jaworski, Tarek Ziadé

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.

What is metaprogramming?

Maybe we could find a good academic definition of metaprogramming, but this is a book that is more about good software craftsmanship than about computer science theory. This is why we will use our own informal definition of metaprogramming:

"Metaprogramming is a technique of writing computer programs that can treat themselves as data, so they can introspect, generate, and/or modify themselves while running."

Using this definition, we can distinguish between two major branches of metaprogramming in Python:

  • Introspection-oriented metaprogramming: Focused on natural introspection capabilities of the language and dynamic definitions of functions and types
  • Code-oriented metaprogramming: Metaprogramming focused on treating code as mutable data structures

Introspection-oriented metaprogramming concentrates on the language's ability to introspect its basic elements, such as functions, classes, or types, and to create...
