Instead of

    os.system(cmdstring)

try using

    the_output = os.popen(cmdstring).read()

to run the command and get the output. There are other variations
to capture stderr or combined output etc.

If you want to do popen(cmdstring) from a python program that does not _itself_
have a console window, look into running _that_ using the pythonw.exe (note "w")
interpreter instead of the python.exe interpreter, as others have mentioned.
