As a simple aid, for those struggling with
@l3uddz script, (presuming ur on OSX) if you have installed python from python.org (v2.7 remember per the notes), it comes with a little utility to create the py files. Once installed go to the python folder in applications and you will see idle.app (integrated development environment). Fire it up and then choose file, new .. from there it's straightforward and will save the file in py format. Remember as per previous posts to grab the RAW format code (no funny characters/?? On the end of each line and change as per instructions..)
Don't disagree with previous comments re. Capability but it's in your own hands.
