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.

This chapter explained one of the most complex topics in the book. We discussed the reasons and tools for building Python extensions as a way of bridging Python with other languages. We started by writing pure C extensions that depend only on the Python/C API and then reimplemented it with Cython to show how easy it can be if you only choose the proper tool.

There are still some reasons for doing things the hard way and using nothing more than the pure C compiler and the Python.h headers. Anyway, the best recommendation is to use tools such as Cython because this will make your code base more readable and maintainable. It will also save you from most of the issues caused by incautious reference counting and memory mismanagement.

Our discussion of extensions ended with the presentation of ctypes and CFFI as alternative ways to solve the problems of integrating shared libraries. Because they do not require writing custom extensions to call functions from compiled...
