Python Tkinter Radiobutton

In this article we show how to create radio buttons using Tkinter and python

A Radiobutton shows multiple choices to the user out of which, the user can select only one out of them. You can then attach a method or function to that button.

Syntax

myradio = Radiobutton(top, options)

Methods

The radiobutton widget provides the following methods.

Example

Here are some examples

from tkinter import *

def radioselected():
   selection = "You selected the option " + str(var.get())
   label.config(text = selection)

root = Tk()
var = IntVar()
R1 = Radiobutton(root, text="Option 1", variable=var, value=1,
                  command=radioselected)
R1.pack( anchor = W )

R2 = Radiobutton(root, text="Option 2", variable=var, value=2,
                  command=radioselected)
R2.pack( anchor = W )

R3 = Radiobutton(root, text="Option 3", variable=var, value=3,
                  command=radioselected)
R3.pack( anchor = W)

R4 = Radiobutton(root, text="Option 4", variable=var, value=4,
                  command=radioselected)
R4.pack( anchor = W)


label = Label(root)
label.pack()
root.mainloop()

This will display something like this

another example

# Importing Tkinter module
from tkinter import *
from tkinter.ttk import *
 
# Create Tkinter window
win = Tk()
win.geometry('200x200')
 
# Tkinter string variable
v = StringVar(win, "1")
 
# Style class to add style to Radiobutton
# it can be used to style any ttk widget
style = Style(win)
style.configure("TRadiobutton", background = "light blue",
                foreground = "red", font = ("arial", 12, "bold"))
 
# Dictionary to create multiple buttons
values = {"RadioButton 1" : "1",
          "RadioButton 2" : "2",
          "RadioButton 3" : "3",
          "RadioButton 4" : "4",
          "RadioButton 5" : "5"}
 
# Loop is used to create multiple Radiobuttons
for (text, value) in values.items():
    Radiobutton(win, text = text, variable = v,
                value = value).pack(side = TOP, ipady = 5)

mainloop()
