[Tkinter] Grid the radio buttons

[Joni_Engr]

Hi, yes now I able to run this code having radio buttons which are arranged in rows and cols and are linked together. The buttons A and B are linked and have their value in same variable. Same is true for buttons C and D.

Now I need to print their their values when the radio button is selected but I it is not printing the values in the code below.

import tkinter as tk
 
root = tk.Tk()
 
var_ab = tk.IntVar()
var_cd = tk.IntVar()
 
tk.Label(root, 
        text="""Radio Buttons""",
        justify = tk.LEFT).grid (row = 1, column = 1)
 
tk.Radiobutton(root, 
               text="A",
               padx = 20, 
               variable=var_ab, 
               value=1).grid (row = 2, column = 1)
 
tk.Radiobutton(root, 
               text="B",
               padx = 20, 
               variable=var_ab, 
               value=2).grid (row = 2, column = 2)

tk.Radiobutton(root, 
               text="C",
               padx = 20, 
               variable=var_cd, 
               value=3).grid (row = 3, column = 1)

tk.Radiobutton(root, 
               text="D",
               padx = 20, 
               variable=var_cd, 
               value=4).grid (row = 3, column = 2)

print("The Variable AB = " , var_ab)
print("The Variable CD = " , var_cd)

root.mainloop()
