perhaps not 'the easiest', but:

if it's going to be running on a linux tty,

    con = file('/dev/tty', 'rw')
    fcntl.ioctl(con.fileno(),
                0x4B30, # KDMKTONE, from linux/kd.h
                1190000/2000 + (100 << 16))

will beep the speaker at 2kHz for 100 ticks.

if it's going to be running on a console that knows how to beep,

    curses.wrapper(lambda dummy: curses.beep())

(this might actually be what you're wanting, but it's only slightly
better than 'print "\a"').


me, I vote for

    os.system(conf.soundprog, conf.sounds.beep)

:)
