Works for me - on a terminal using linux. BUT what not works is this:
python /tmp/test.py | cat
(test.py contains your code of course) The reason is buffered pipes being
used. Try this:
import time, sys
for i in range(4):
print 'On'
sys.stdout.flush()
time.sleep(1)
print 'Off'
sys.stdout.flush()
time.sleep(1)
