Hi Gerry,
The currently published version of Python Add-On is still experimental, but we are working hard on the final version which will come next year.
I can tell you for sure, that the final version of Python API will be an external Python module and it will be available using pip (PyPI), so you will be able to run your Python script outside of ARCHICAD also (of course a running ARCHICAD is needed). Many of you requested this feature during the Beta Test of the Experimental Python API, so it got high priority on our list.
The answer for your request/question is no, it's not possible currently, but please be patient.
Regards,
Tibor
