Looks like the author of the script file has tried to create a Python
Shell script.  This link describes them in detail:

http://www.dreamsyssoft.com/python-scripting-tutorial/intro-tutorial.php

Not sure whether the example originally quoted would work, I imagine it
might on some 'nix operating systems.

The more common first line is:

    #!/usr/bin/env python

If you start a script file with this line and make the file executable,
you can then run the script from the command line without having to
preface it with a reference to your Python executable.  Eg:

    my-script.py


versus

    python my-script.py
