That's all well and good, but it's got nothing to do with the
OP's problem: he's got a program that's already running and he
wants to write a Python program that can "attach" pipes to that
already running program's stdin/stdout.  I know there's no way
to do that under Unix.  IIRC, the OP is running Win32, and I'm
not quite as confident that it can't be dont under Win32, but I
don't think it can.
