The book is called 'Python Programming for the absolute beginner'. It is written by Michael Dawson and published by Premier Press.
I have to say that as someone that has no experience in programming what so ever, I am hooked! I need to learn Python for a job I am starting next month and to say I felt a little worried at the idea is an understatement. Since going through the first few chapters of this book (and having the support of this group) I can not wait to learn more!

What book are you working through? That is a pretty interesting exercise.
