Сделайте Tkinter Scale Control Sound Volume?

Question

Я хотел бы иметь возможность управлять громкостью звука с помощью шкалы Tkinter в моем коде ниже: Это mp3-плеер, который я делаю, и я использую для этого mp3play. И это мой первый раз, когда мы имеем дело с чем-то подобным, поэтому, если вы, ребята, могли бы предложить лучший способ организации, тогда это было бы здорово.

спасибо.

Мой код:

# -*- coding: utf-8 -*-

Music = os.listdir(os.path.join(os.path.expanduser('~'), 'Desktop', 'NarutoLibMin')) 
MusicPath = os.path.join(os.path.expanduser('~'),'Desktop', 'NarutoLibMin') 
count = '' 
mp3 = '' 
VolumeSlider = '' 
print Music 

def Core(): 
    global mp3; global count; global VolumeSlider 
    count = 0 

    root = Tkinter.Tk() 
    root.option_add('*Font', 'courier 12') 
    root.option_add('*Background', 'light blue') 
    root.configure(bg='light blue') 

    mp3 = mp3play.load(os.path.join(MusicPath, Music[count])) 

    def centerRoot(w = 729, h = 170): 
     ws = root.winfo_screenwidth()

Ваш код может выглядеть следующим образом:

Core().Run() 

Я не могу проверить это, потому что я использую Linux и MP3Play (вероятно) работает только с Windows.
