           About the authors
           Steven Lott has been programming since computers were large, expensive, and 
           rare. Working for decades in high tech has given him exposure to a lot of ideas and 
           techniques—some bad, but most are useful and helpful to others. 
           Steven has been working with Python since the '90s, building a variety of tools 
           and applications. He's written a number of titles for Packt Publishing, including 
           Mastering Object-Oriented, Modern Python Cookbook, and Functional Python 
           Programming.
           He's a technomad, and lives on a boat that's usually located on the east coast of the 
           US. He tries to live by the words "Don't come home until you have a story."
           Dusty Phillips is a Canadian author and software developer. His storied career 
           has included roles with the world's biggest government, the world's biggest social 
           network, a two person startup, and everything in between. In addition to Python 
           Object-Oriented Programming, Dusty wrote Creating Apps In Kivy (O'Reilly) and is now 
           focused on writing fiction.
               Thank you to Steven Lott, for finishing what I started, to all my readers for 
               appreciating what I write, and to my wife, Jen Phillips, for everything else.
