Have a look at ubuntu/casper and
http://www.supergrubdisk.org/wiki/Loopback.cfg to see how it's done
properly. It short: you completely miss the point and "running a
program/python script in GRUB" makes little sense. To load linux/initrd
from image from GRUB it's enough 4 simple commands: loopback, linux,
initrd, boot. But you need special initrd to do the rest
