[Tkinter-discuss] as close windows by separate modules

[craf]

Hi.

I have two modules: 

main.py---------------------

from tkinter import *
from tkinter import ttk
from code import Option


class App:
    def __init__(self, master):
        master.protocol("WM_DELETE_WINDOW",Option.quit)


master = Tk()
master.geometry('640x480')
app = App(master)
master.mainloop()

code.py---------------------

from tkinter import messagebox
from tkinter import *
from tkinter import ttk


class Option:
    def quit():
        if messagebox.askyesno(message='Close window'):
            master.quit()

I want to press the close button and close the main window to run the
module main.py.


But I can not, the error it throws is: "NameError: global name 'master'
is not defined"

I appreciate any suggestions.

Regards.
