To get the most out of this book

Intermediate knowledge of Python is required though many topics are covered in a way that even beginners should have an understanding of the basic principles being covered. Specifically, the experience of using both the interactive Python interpreter and writing Python files, how to import modules, and how to work with object-oriented principles is assumed.

This book uses Python 3.6 for the examples, unless otherwise indicated. While alternative implementations are briefly discussed, the book assumes the basic CPython implementation is being used.
