Explain it ? No, I don't think I can do that.

Give you something that works ? - Maybe.

Here's what I tried - paths hard-coded for my system.
The first time it starts up, no argument is successfully passed.
Second time it works as hoped for ....

I'm not sure if it is always safe to just prepend the python command - 
may depend on the Python installation. You should be able to avoid any 
danger there by using the code used from the codeEditor to run a script 
(see function runScript)
