What he adds however is some very useful information on the structure of a python program and how to do things like if staements and loops . He also provides working example scripts that can be used as the base of a program .

If you have a programming background in C you can dig the information out of the python documentation from python.org. If you dont Phils pdf file is a  very valuable guide .
