我正在尝试为页面制作一个退出按钮，但由于某种原因它有错误，我不知道如何解决

Question

I am trying to make an exit button with the code I do import tkinter* in here

from tkinter import*
from tkinter import ttk
from PIL import Image,ImageTk
import os

def iExit(self):
        self.iExit=tkinter.askyesno("Face Recognition","Are you sure you want to exit?")
        if self.iExit >0:
            self.root.destroy()
        else:
            return 

and I got the error

I know that I cant put tkinter inside the code but i don't know how to solve it. The error that I am getting is here

Exception in Tkinter callback

  File "C:\Users\user\AppData\Local\Programs\Python\Python311\Lib\tkinter\__init__.py", line 1948, in __call__

askyesno is defined in thetkinter.messagebox module. Import it from there:

from tkinter.messagebox import askyesno
