Python Tkinter Quiz Project Validation Issue

I am making a quiz program using the Python GUI interface. When the start button is selected, a random question is generated. User will next select true of false and then select the submit button.

How do I do this ?:
I need to check the user attempt against the answer and display either ‘Question X is correct’ or ‘Question X is incorrect! in the Scrolled Text below’.

import tkinter as tk 
from tkinter import ttk, Label, scrolledtext, IntVar, Radiobutton

                                    # resized at both width and height 
        # self._window Title
        self._win.title("Python Quiz") # give it a title
        self._win.geometry("400x450")     # give it an initial width and height

        # Button
        actionFrame = ttk.Frame(self._win)

        # Use StringVar to Change the Label Text

        self._myLabel_text.set("Question will appear here")
