Steven Lott has been programming since the 1970s, when computers were large, expensive, and rare. As a contract software developer and architect, he has worked on hundreds of projects, from very small to very large. He's been using Python to solve business problems for over 10 years. He's particularly adept struggling with gnarly data representation problems. His other titles include Mastering Object-Oriented Python and Python for Secret Agents, both by Packt Publishing. After spending years as a technomad—living in various places on the east coast of the US—he has dropped the hook in the Chesapeake Bay. He blogs at http://slott-softwarearchitect.blogspot.com.
