Tkinter - How can I add a "bell sound" when an event accurs?

Question

I have a simple question about the bell sounds in Tkinter. How can I add one of them when my progress bar is completed or when I open a message box window with the filedialog.asksaveasfilename() function?

You can use the method bell() to trigger a system bell sound.

Here is an example how you can play it when the progress bar completes.

import tkinter as tk
import tkinter.ttk as ttk

root = tk.Tk()

def work():
    if progressbar['value'] == 0:
        but1['state'] = 'disabled'
    if progressbar['value'] >= progressbar['maximum']:
        root.bell()
        but1['state'] = 'normal'
        progressbar['value'] = 0
        return
    progressbar['value'] += 1
    root.after(100, work)

progressbar = ttk.Progressbar(root, length=200, maximum=10, value=0)
progressbar.grid(row=1)

but1 = ttk.Button(root, text='Start', command=work)
but1.grid(row=2)

root.mainloop()

Similarly, with the help of this example, I hope you can implement it with message pop-ups as well.

The Tkinter bell() is the default sound of the operating system, to change the bell sound in the Tkinter application change the system default alert sound. For example,

• on macOS, one can do it by choosing Apple menu > System Preferences, click Sound, then click Sound Effects.

• Here is how one can do it on Windows.
• Here is how one can do it on Linux.
