Definitively this is not a book to start learning the Python syntax. What it does is give an overview over some advanced programming issues.
Being a novice concerning Python my task was to embed Python scripting into a C application. The chapter about embedding really gave me a head start saving me a week of work. Yet some information still had to be collected from the Internet like how to make the builtins available.
If You want to do serious programming with Python the book is a nice start to get an idea of what can be done and how to get moving.
