I have updated the torrent file that is current available. It was brought to my attention there were many errors when the sample programs were ran, and some confusion within the book itself.
I have changed the included sample programs so both Python 2.x and Python 3 versions are available. I have also modified Chapter 4 of the book to explain that Python 2.x is used for all the examples within the book. Hopefully this will reduce reader confusion.
If you find any problems or have suggestions, please let me know.
