# code after loop

I want to read in the Excel file and when it is done I want to press the exit button and the code after the mainloop should be executed. I already tried update_idletasks() but this also doesn't work. So how do I exit the window and the loop after pressing the exit button?

see [this question](https://stackoverflow.com/questions/2307464/what-is-the-difference-between-root-destroy-and-root-quit) to decide on whether to use `quit` or `destroy` (on the root window), then the code after `mainloop` will get executed — Matiiss, Sep 19 '22 at 14:15
yoi want to keep running the tkinter application while executing the *code after loop*? — Faraaz Kurawle, Sep 19 '22 at 14:27
After I got the filename and return it into my main programm I don't need the tkinter app anymore @FaraazKurawle so I think destroy will do the job. — Markus, Sep 19 '22 at 14:32

Change the location of the button so it is in view:

Example:


button_exit.place(x=50, y=50, height=30)

Then it responds as it should in my setup.

Admittedly 50,50 is not a good location! – Ronald van Elburg Sep 19 '22 at 14:23

The output of messagebox.askquestion is not boolean, but rather a string containing 'yes' or 'no'. So you need to test the string value. The extra code in case of 'no' should go into a function. Nothing stops you from calling that function after a yes aswell. With a small change to exit and adding a function 'extracode' you can make this all work:


def extracode():
    print('Die Gedanken sind frei')

def exit():  
    bExit =  messagebox.askquestion("Exit", "Do you want to Exit?")
    print(bExit)
    if bExit == 'yes':
        window.destroy()
    else: 
        extracode()
