Hi,

How can I position the radio buttons with with grid command and rows and col

import tkinter as tk

root = tk.Tk()

var_1 = tk.IntVar()
var_2 = tk.IntVar()

tk.Label(root, 
        text="""Radio Buttons""",
        justify = tk.LEFT,
        padx = 20).pack()

tk.Radiobutton(root, 
               text="A",
               padx = 20, 
               variable=var_1, 
               value=1).pack(anchor=tk.W)

tk.Radiobutton(root, 
               text="B",
               padx = 20, 
               variable=var_1, 
               value=2).pack(anchor=tk.W)


tk.Radiobutton(root, 
               text="C",
               padx = 20, 
               variable=var_2, 
               value=1).pack(anchor=tk.W)

tk.Radiobutton(root, 
               text="D",
               padx = 20, 
               variable=var_1, 
               value=2).pack(anchor=tk.W)

root.mainloop()

a) There is a special sub-forum for tkinter questions
b) You are packing now, where on the grid do you want them?

Like so:

import tkinter as tk

root = tk.Tk()

var_1 = tk.IntVar()
var_2 = 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_1,
value=1).grid (row = 2, column = 1)

tk.Radiobutton(root,
text="B",
padx = 20,
variable=var_1,
value=2).grid (row = 3, column = 1)


tk.Radiobutton(root,
text="C",
padx = 20,
variable=var_2,
value=1).grid (row = 2, column = 2)

tk.Radiobutton(root,
text="D",
padx = 20,
variable=var_1,
value=2).grid (row = 3, column = 2)

root.mainloop()

You cannot use pack() and grid() in the same frame, so make a frame for the radio buttons.

import tkinter as tk

root = tk.Tk()

var_1 = tk.IntVar(0)

tk.Label(root, text="""Radio Buttons""", justify=tk.LEFT, padx=20).pack()

radio_frame = tk.Frame(root)
radio_frame.pack()
for index, button in enumerate('ABCD'):
    button = tk.Radiobutton(radio_frame, text=button, variable=var_1, value=index)  # Buttons are added to radio_frame, not root
    button.grid(row=index // 2, column=index % 2, padx=5, pady=5)

root.mainloop()

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()

#! /usr/bin/env python3.10
import tkinter as tk

root = tk.Tk()

def show():
    print(f' Variable AB -> {var_ab.get()}')
    print(f' Variable CD -> {var_cd.get()}')

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,
               command=show,
               value=1).grid (row = 2, column = 1)

tk.Radiobutton(root,
               text="B",
               padx = 20,
               variable=var_ab,
               command=show,
               value=2).grid (row = 2, column = 2)

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

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



root.mainloop()

Output: Variable AB -> 1
 Variable CD -> 0
 Variable AB -> 1
 Variable CD -> 4
 Variable AB -> 1
 Variable CD -> 3
 Variable AB -> 2
 Variable CD -> 3
