Important things to note

• The book uses a fun, text-based game theme as a vehicle to explain various application development aspects. However, the book itself is not about developing game applications!
• Every chapter will have its own set of Python source files. Although we will talk through most of the code, you should keep the relevant files at hand. See the Downloading the example code section for more details.
• The following is relevant if you are reading the electronic version of this book. Most of the code illustrated in this book is created as images. Try to use 100% zoom for a better reading experience as these code snapshots should appear crisp at zoom level.
• The solutions to the exercises (if any) are generally not provided.
• This book provides several external links (URLs) for further reading. Over time, some of these links might end up being broken. If that ever happens, try searching the web with the appropriate search terms.
• Some experienced readers may find the code explanation a bit verbose. In this case, you can review the code provided in the supporting material for the book.
