While the utility of a "portable PDF" is undeniable, it is essential to acknowledge the sustainability of the technical publishing industry. High-quality technical writing requires immense effort. Ramalho spent years updating the second edition to reflect changes in the language up to Python 3.10.

: You can find all the scripts and exercises for the second edition in the fluentpython/example-code-2e repository on GitHub. Companion Website fluentpython.com
