Can I use sys.exit() to stop a Tkinter program

Question

Is there a problem with using sys.exit() to stop a Tkinter program?

I know normally people use root.destroy() why is that?

Answer 1

Of course but it will terminate the entire program, including your app.

According to here: https://www.daniweb.com/programming/software-development/threads/66698/exit-a-tkinter-gui-program. root.destroy is a safe, dependable way to exit your Tkinter app. From the link:

destroy() just terminates the mainloop and deletes all widgets. So it seems to be safer if you call your app from another Tkinter app, or if you have multiple mainloops.
