tkinter is a GUI Library, this code creates simple no-text buttons:

 import tkinter as tk
 class Callback:
     def __init__(self, color):
         self.color = color
     def changeColor(self): 
         print('turn', self.color)
 c1 = Callback('blue')
 c2 = Callback('yellow')
 B1 = tk.Button(command=c1.changeColor) 
 B2 = tk.Button(command=c2.changeColor) 
 B1.pack()
 B2.pack()
