Can you tell us what book it is ?

If this is just your first and only book so far,
IMO, I think you can look at another one or two
I recently re-discovered Steven Lott's excellent free book "Building
Skills in Python" (http://homepage.mac.com/s_lott/books/
python.html#book-python)
and then there is the popular "Think Python" by Allen Downey
