Note that the OP was including this inside a pre-existing 
shell-script that was working for their purposes.  Lie's 
suggestion allows Python to be embedded in the existing 
shell-script; to use your solution, the OP would have to rewrite 
their entire existing script in Python (not necessarily a bad 
thing in my book, for maintainability purposes, but does not 
appear to be at the top of their list of things to do)
