How To Write To Txt File Which Options Been Selected?

My current goal is to send data to a txt file of which out of the 3 radio buttons have been selected for each option. here is my current code of radio buttons: import tkinter as tk

Solution 1:

Look inside your button widget, command = open.. you're basically calling the button that's why the error is showing up.

Change it to command = send, and also take out the 'tk' from function, as you don't need it.
