I am in a situation where my code takes extremely long to run and I don't want to be staring at it all the time but want to know when it is done.

How can I make the (Python) code sort of sound an "alarm" when it is done? I was contemplating making it play a .wav file when it reaches the end of the code...

Is this even a feasible idea? If so, how could I do it?

On Windows

import winsound
duration = 1000  # milliseconds
freq = 440  # Hz
winsound.Beep(freq, duration)

Where freq is the frequency in Hz and the duration is in milliseconds.

On Linux and Mac

import os
duration = 1  # seconds
freq = 440  # Hz
os.system('play -nq -t alsa synth {} sine {}'.format(duration, freq))

In order to use this example, you must install sox.

On Debian / Ubuntu / Linux Mint, run this in your terminal:

sudo apt install sox

On Mac, run this in your terminal (using macports):

sudo port install sox

Speech on Mac

import os
os.system('say "your program has finished"')

Speech on Linux

import os
os.system('spd-say "your program has finished"')

You need to install the speech-dispatcher package in Ubuntu (or the corresponding package on other distributions):

sudo apt install speech-dispatcher
