My first idea/request: have a blank line, a line with only a '--' 
(without quotes), and then your signature at the bottom of your posts. 
White space aids readability and readability counts.  :)

How are those scripts being run?  Microsoft Windows or Unix/Linux/BSD?

Typically, the first line of a script will say which version of Python 
is needed.  For example, on a *nix type system:

     #!/usr/bin/python2
