If you want to get the exit-code of the called program
say:
>>> print os.system('dir c:\\temp')
0

If you want to get the output of the called program
say:
>>> print os.popen('dir c:\\temp').read()

If you want to exchange information between two processes
as between to subroutines by para list, you have to do
a little bit more.
You have to do something like:
 - sockets       or
 - shared memory or
 - named pipes
