py2exe - return information from .exe program

[Miranda Evans]

Assume xyz.exe is a program that was produced from  xyz.py by running
the py2exe utility.  Currently, xyz.exe displays information on the
screen, but it does not return information to the calling program. 
Can xyz.py be modified so that xyz.exe returns a value (e.g. a string)
to the process that called it?  Can anyone point me to a sample .py
script which, when 'compiled' with py2exe produces a .exe that returns
information to the calling program?  Thank you.
