On Windows, if you want to just make the computer make a beep sound:

import winsound
frequency = 2500  # Set Frequency To 2500 Hertz
duration = 1000  # Set Duration To 1000 ms == 1 second
winsound.Beep(frequency, duration)


The winsound.Beep() can be used wherever you want the beep to occur.

Here is what the above code is Doing:
1. Import the winsound module.
2. Set the frequency to 2500 Hertz.
3. Set the duration to 1000 milliseconds.
4. Call the winsound.Beep() function.
