This book will introduce you to the Python programming language. It’s aimed at be‐ ginning programmers, but even if you’ve written programs before and just want to add Python to your list of languages, Introducing Python will get you started.

This book provides a full set of exercises in which we will build a fully functional HTML canvas game. Though not a direct clone, the game is inspired by the 1979 Atari classic, Asteroids. The code is provided for you and is introduced piece by piece over the various chapters of the book. If you’d like to try Asteroids, or if you’ve never played it, the the modern Atari version can be played at https://atari.com/arcade#!/arcade/ asteroids/play.

Although originally designed by Google for the kinds of problems Google works on —large, distributed network applications—Go is now a general-purpose program‐ ming language useful in a wide variety of software domains. Many companies have started using Go because of its simplicity, ease of use, performance, low barrier of entry, and powerful tooling.
