This book is for those of you who want to learn how to program in Python. It is intended to suit a wide audience, from neophyte programmer to advanced computer wiz. If you have never programmed before, you should start by reading Chapter 1 and continue until you find that things get too advanced for you (if, indeed, they do). Then you should start practicing, and write some programs of your own. When the time is right, you can return to the book and proceed with the more intricate stuff. If you already know how to program, then some of the introductory material might not be new to you (although there will probably be some surprising details here and there).
