My full code is :

import winsound
import multiprocessing

#Initialisation
fenetre=Tk()
frame = Frame(fenetre, width=200, height=100)
instance = 'Instance'


#Fonctions

def key(event):

     instance = 'Instance'
     hitkey = event.char
     instance = multiprocessing.Process(target=player, args=(hitkey,))
     instance.start()



def player(hitkey):


     winsound.PlaySound(hitkey + '.wav', 
winsound.SND_FILENAME|winsound.SND_NOWAIT|winsound.SND_ASYNC)



#TK
frame.focus_set()
frame.bind("<Key>", key)
frame.pack()
fenetre.mainloop()

The problem is that I don't know where to put that clause.

I hope this helps:


#Import
from tkinter import *
import wave
import winsound
import multiprocessing


#Fonctions

def key(event):
    instance = 'Instance'
    hitkey = event.char
    instance = multiprocessing.Process(target=player, args=(hitkey,))
    instance.start()


def player(hitkey):
    winsound.PlaySound(hitkey + '.wav', 
winsound.SND_FILENAME|winsound.SND_NOWAIT|winsound.SND_ASYNC)


if __name__ == "__main__":
    # This part will be run if the file is run as the main script.
    #
    # The multiprocessing module will import this file to run the
    # "player" function, but __name__ won't be "__main__" when it does
    # so, therefore this bit of code won't be run.

    #Initialisation
    fenetre = Tk()
    frame = Frame(fenetre, width=200, height=100)
    instance = 'Instance'

    #TK
    frame.focus_set()
    frame.bind("<Key>", key)
    frame.pack()
    fenetre.mainloop()
