Forgot to mention. If you want to create an executable. You can try to 
configure the package Linker using PyInstaller as the driver:

    https://pyinstaller.org/en/stable/operating-mode.html

Note that Linker does not take language e.g. ("Python") you just write:

    package Linker is
       for Driver use "pyinstaller.exe";

You have to tinker a bit since there is no object files to feed the 
Linker. Maybe you could sell it *.py as an "archive" (static library). 
Whatever... (:-))
