Using only the modules that come with a standard python 2.6 installation, would it be possible to play a simple beeping noise?
If you're on a Unix terminal, you can print "\a" to get a terminal bell:
>>> def beep():
... print "\a"
>>> beep()
Of course, that will print a newline too… So sys.stdout.write("\a")
might be better. But you get the idea.
