Python Tkinter - Get Selection On Radiobutton

I need to retrieve the value of Radiobutton clicked and then use this value . What is the way to retrieve the value of a Radiobutton clicked ? the code to setup the Radiobutton is:

Solution 1:

This is one solution: Create a tk.IntVar() to track which button was pressed. I'm assuming you did a from tkinter import *.

radio_var = IntVar()

You'll need to change the way you declared your buttons:

radio_uno = Radiobutton(Main,text='Config1', value=1,variable = radio_var)
radio_due = Radiobutton(Main,text='Config2', value=2,variable = radio_var)
radio_tre = Radiobutton(Main,text='Config3', value=3,variable = radio_var)

Then use the get() method to view the value of radio_var:

which_button_is_selected = radio_var.get()

Then you can make an enum or just three if clauses that'll do stuff depending on which button is chosen:

if(which_button_is_selected == 1):
    #button1codeelif(which_button_is_selected == 2):
    #button2codeelse(which_button_is_selected == 3):
    #button3code
