I would like to acknowledge the gang at Developer Shed: Jack and Jay Kim, whose constant hatred is an inspiration, Charles Fagundes, who made me an editor and not just a writer, Keith Lee, who provided coding support, and a special thanks to Jenny Ruggieri, who got me the job that got me this book. Lastly, I'd like to thank all of the people that worked on the previous editions of this book for laying the groundwork, and the Editors Carol Long, Jenny Watson, Ed Connor, and Chris McAvoy who helped me meet deadlines no matter how much I didn't want to.

I would also like to acknowledge Guido Von Rossum, without whom there would be no language to write about.
