The radiobutton widget in Tkinter allows the user to make a selection for only one option from a set of given choices. The radiobutton has only two values, either True or False.
If we want to get the output to check which option the user has selected, then we can use the get() method. It returns the object that is defined as the variable. We can display the selection in a label widget by casting the integer value in a string object and pass it in the text attributes.
Example
# Import the required libraries
from tkinter import *
from tkinter import ttk
# Create an instance of tkinter frame or window
win = Tk()
# Set the size of the window
win.geometry("700x350")
# Define a function to get the output for selected option
def selection():
selected = "You selected the option " + str(radio.get())
label.config(text=selected)
radio = IntVar()
Label(text="Your Favourite programming language:", font=('Aerial 11')).pack()
# Define radiobutton for each options
r1 = Radiobutton(win, text="C++", variable=radio, value=1, command=selection)
r1.pack(anchor=N)
r2 = Radiobutton(win, text="Python", variable=radio, value=2, command=selection)
r2.pack(anchor=N)
r3 = Radiobutton(win, text="Java", variable=radio, value=3, command=selection)
r3.pack(anchor=N)
# Define a label widget
label = Label(win)
label.pack()
win.mainloop()Output
Executing the above code will display a window with a set of radiobuttons in it. Click any option and it will show the option that you have selected.
