• Offvalue - checkbutton is an associated control variable that will be set to 0 when it is cleared (off).
• OnValue - checkbutton is an associated control variable that will be set to 1 when it is cleared (on).

Program

from tkinter import *
import tkinter.messagebox
a= Tk()
a.geometry("400x400")
def music():

def video():
   tkinter.messagebox.showinfo(title="video",message="you select video")
def photo():
   tkinter.messagebox.showinfo(title="photo",message="you select photo")

CheckVar1 = IntVar()
CheckVar2 = IntVar()
CheckVar3 = IntVar()

C1 = Checkbutton(a, text = "Music",activebackground="black" , activeforeground="white"\
                 ,bg="green",bd=10,variable = CheckVar1,\
                 onvalue = 1, offvalue = 0,command = music).pack()



Label(a, text="").pack()#space


C2 = Checkbutton(a, text = "video",activebackground="black" ,activeforeground="white"\
                 ,bg="green",bd=10,variable = CheckVar2\
                 ,onvalue = 1, offvalue = 0,command = video).pack()
