python 3x - i want to stop while with tkinter button

I plan to make a simple app with python3.

Watch the folder and create a new text file
It is to do some processing in that file.

To monitor the folder there
Usewhileto monitor folders
Variable to updateupdate_intarbal
watch_mode
Ifwatch_modeis 1, watch it, and exit if 0
I'm thinking of assembling it.

is

Launch the app
[App launch]
↓
[Start tkinter frame (Label: Monitor mode andButton: STOP)]
↓
[while looping (watch_mode = 1for monitoring)]

Exit the app
[Update towatch_mode = 0by pressingButton: STOP in the tkinter frame]
↓
[Exit the while loop (watch_mode = 0)]
↓
[App stop]

If I want to stop, press tkinter's STOP button
It feels likewatch_modeis updated to 0 and exits the while loop

I managed to write the following code, but it was far from ideal ...
For now,tkinterandwhiledon't work together
Also, even if you press the stop button, watch_mode is not updated and it becomes an infinite loop.

If i have any knowledge, please give me advice.

import tkinter as tk
from time import sleep
def main ():
    watch_mode = 1 #Automatic conversion mode
    while_loop = 0 #Manage initial behavior
    update_intarval = 5 #Update time (s)
    while watch_mode == 1:
        if while_loop == 0: Only run # 1
            while_loop = 1
            showinfo = tk.Tk ()
            frame_top = tk.Frame (showinfo, bd = 2, relief = "ridge")
            frame_top.pack (fill = "x", pady = 2)
            label1 = tk.Label (frame_top, text = "It is a monitoring mode")
            label1.pack (side = "left")
            frame_bottom = tk.Frame (showinfo, bd = 2)
            frame_bottom.pack (fill = "x")
            def stop_convert ():
                watch_mode = 0
                showinfo.destroy ()
            button1 = tk.Button (frame_bottom, text = "STOP", bg = "# f0e68c", fg = "# ff0000", command = stop_convert)
            button1.pack ()
            showinfo.mainloop ()
        sleep (update_intarval)
        print (watch_mode)
if __name__ == '__main__':
    main ()

    I tried using.afteroftkinteras advised.
    It became the movement that I thought of for the time being.

    Here's the code.

    Please give me any advice. m (_ _) m

    import tkinter as tk
def main ():
    after_id = None
    repet_nums = 0
    update_intarval = 100 #Update time (msec)
    def convert_data ():
        global after_id
        #### Write the operation you want to repeat in the lower part #################################### #####
        global repet_nums
        repet_nums + = 1
        print ("If you look at the folder and you have a new file, you can convert it", repet_nums)
        if repet_nums == 1:
            print ("ikkaime")
        ################################################## ###########################
        after_id = showinfo.after (update_intarval, convert_data)
    def start ():
        global repet_nums
        repet_nums = 0
        convert_data ()
    def stop_convert ():
        global after_id
        if after_id:
         showinfo.after_cancel (after_id)
         after_id = None
         showinfo.destroy ()
    showinfo = tk.Tk ()
    frame_top = tk.Frame (showinfo, bd = 2, relief = "ridge")
    frame_top.pack (fill = "x", pady = 2)
    label1 = tk.Label (frame_top, text = "It is a monitoring mode")
    label1.pack (side = "left")
    frame_bottom = tk.Frame (showinfo, bd = 2)
    frame_bottom.pack (fill = "x")
    button1 = tk.Button (frame_bottom, text = "STOP", bg = "# f0e68c", fg = "# ff0000", command = stop_convert)
    button1.pack ()
    start ()
    showinfo.mainloop ()
if __name__ == '__main__':
    main ()
