By the way your code fails to execute with python2.6 in ubuntu it says it
can't find test.py even though it is there. It's actually pretty strange.
I even put '.' In the path and I tried adding the full path to test.py. I
have not run into this problem before with python.

The code follows:
---------
# runTest.py provide interface and run test.py engine
import subprocess
# launch the engine child process:
engine = subprocess.Popen("python test.py",
universal_newlines=True, stdin=subprocess.PIPE, stdout=subprocess.PIPE)
# user interaction main loop:
while(True):
# get a move from user:
playerMove = raw_input("Enter a move ")
# exit if done:
if playerMove == 'exit':
break
# send player move over to engine:
engine.stdin.write('%s\n' % playerMove)
# get reply from engine:
engineMove = engine.stdout.readline().strip('\n')
# show response from engine:
print "Engine response:>%s<" % engineMove
# end of while loop
# termination processing:
if engine.poll() is None:
# kill the subprocess:
engine.kill()
