You have to associate the Radiobuttons with a variable, for example:

from tkinter import *

root = Tk()
root.grid()
v = IntVar()
button = Radiobutton(root, text = "Test RadioButton", variable=v, value=1)
button.grid(row = 0, column = 0, sticky = W)

button = Radiobutton(root, text = "Test RadioButton2", variable=v, value=2)
button.grid(row = 1, column = 0, sticky = W)

root.mainloop()
