I am creating a brightness toggle on Python. I am using the Tkinter module to create a sider function. I have successfully created a slider to increase/decrease the volume. However, I want to translate this into one where I can increase/decrease the screen's brightness. Here is my volume code and output.

I am currently using macOS Monterey Version 12.2.1.

        #The GUI player
import pygame
from pygame import mixer
from tkinter import *


# Makes a new window and stores it inside the root variable.
root = Tk()

mixer.init() # initialising the mixer

# Coding the background music
def play_music():
    pygame.mixer.music.load("ArcadeMusic copy.mp3")
    pygame.mixer.music.play(-1)

def set_vol(val):
    volume = int(val) / 100
    mixer.music.set_volume(volume)

root.geometry('300x70')
root.title("Volume")

text = Label(root, text = "Drag the slider to adjust volume")
text.pack()

scale = Scale(root,from_=0,to=100 , orient=HORIZONTAL, command=set_vol)
scale.pack()

play_music()
root.mainloop()

Are you trying to achieve something like this? Or do you want to control desktop brightness?
