Solution 1:

In this code, Label updates every click of Radiobutton using command option of Radiobutton and Label's text variable.

from Tkinter import *

def radio_action():
    value1 = var1.get()
    changeable_label['text'] = value1

the_window = Tk()
the_window.title('Example')

the_window.geometry("200x150")

var1 = StringVar()

changeable_label = Label(the_window, text = "Null")
button1 = Radiobutton(the_window, text = 'Button1', variable = var1,
                     value="Something", command = radio_action)

changeable_label.pack(side = TOP)
button1.pack()
