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.

    you can also do `print "\a",` and it won't do newlineb – RodericDay Dec 11 '12 at 22:42
  • also works on macs however it uses your speaker so if say you have headphones in it will use your headphones or if it is muted it won't work. – Zimm3r Dec 15 '13 at 03:18
  • Works fine for me on Windows 7, even through headphones. – LarsH Mar 18 '14 at 21:00
  • what is the main difference between `print "\a"` and `sys.stdout.write("\a")`? – Mathias711 Jun 27 '14 at 12:07

    @Mathias711 that… is actually a more complex question than it seems. In this case, `print "\a"` is basically the same as `sys.stdout.write("\a\n")`; `sys.stdout.write("\a")` won't always work because `sys.stdout` is usually line buffered (so you won't "see" the write until a newline is written).

On windows:

import winsound         # for sound  
import time             # for sleep

winsound.Beep(440, 250) # frequency, duration
time.sleep(0.25)        # in seconds (0.25 is 250ms)

winsound.Beep(600, 250)
time.sleep(0.25)

On Android with QPython this is how it goes:

import androidhelper
droid=androidhelper.Android()
droid.generateDtmfTones('0',100)

This will place a beep of a certain frequency for certain time.

    It's `generateDtmfTones()`. You're missing an `f`. https://kylelk.github.io/html-examples/androidhelper.html – Shayan Jul 04 '21 at 13:20
