Overview of this book

Even if you find writing Python code easy, writing code that is efficient, maintainable, and reusable is not so straightforward. Many of Python’s capabilities are underutilized even by more experienced programmers. Mastering Python, Second Edition, is an authoritative guide to understanding advanced Python programming so you can write the highest quality code. This new edition has been extensively revised and updated with exercises, four new chapters and updates up to Python 3.10. Revisit important basics, including Pythonic style and syntax and functional programming. Avoid common mistakes made by programmers of all experience levels. Make smart decisions about the best testing and debugging tools to use, optimize your code’s performance across multiple machines and Python versions, and deploy often-forgotten Python features to your advantage. Get fully up to speed with asyncio and stretch the language even further by accessing C functions with simple Python calls. Finally, turn your new-and-improved code into packages and share them with the wider Python community. If you are a Python programmer wanting to improve your code quality and readability, this Python book will make you confident in writing high-quality scripts and taking on bigger challenges

Building packages

Python packages were traditionally built using a setup.py file that contained (part of) the build script. This method usually depends on setuptools and is still the standard for most packages, but we have easier methods available these days. If your project is not too demanding, you can use a small pyproject.toml file instead, which can be much easier to maintain.

Let’s give both methods a try and see how easy it is to build a basic Python package.

Packaging using pyproject.toml

The pyproject.toml file allows for really easy packaging depending on the tooling used. It was introduced in 2015 through PEP-517 and PEP-518. This method was created to improve upon the setup.py file by introducing build-time dependencies, automatic configuration, and making it easier to work in a DRY (Don’t Repeat Yourself) manner.

TOML stands for “Tom’s Obvious, Minimal Language” and is somewhat comparable to YAML and INI files...
