To get the most out of this book

You are encouraged to follow the examples in this book. You will need a computer, an internet connection, and a browser. The book is written for Python 3.12, but it should also work, for the most part, with any recent version of Python 3. We have given guidelines on how to install Python on your operating system. The procedures to do that normally get out of date quickly, so we recommend you refer to the most up-to-date guide on the web to find precise setup instructions. We have also explained how to install all the extra libraries used in the various chapters. No particular editor is required to type the code; however, we suggest that those who are interested in following the examples should consider adopting a proper coding environment. We have offered suggestions on this matter in the first chapter.
