允許多選單選按鈕

如何更改我的代碼以允許選擇多個按鈕，而不是限制爲選中的一個。允許多選單選按鈕

from tkinter import * 

master = Tk() 
master.title("Interests") 
v = IntVar() 

MODES = [ 
     ("Monochrome", "1"), 
     ("Grayscale", "2"), 
     ("True color", "3"), 
     ("Colour separation", "4"), 
    ] 

v = StringVar() 
v.set("0") # sets all visable buttons to unchecked 
for text, mode in MODES: 
    b = Radiobutton(master, text=text, variable=v, value=mode) 
    b.pack(anchor=W)
