Tkinter: messagebox doesn`t work right. (get two windows)

Question

I am using python 3. If I opan an error messagebox, i get two frames, one is emty and one is the error-window. That is my code:

from tkinter import messagebox

messagebox.showwarning('warning', 'warning')

Answer 1

Everything works correctly in your example. The empty window is the main window of Tk. It is always open when you start any Tk program. You can minimize it if you want, but closing it terminates the main loop.

Answer 2

Try this:

  root = tkinter.Tk()
  root.withdraw()
  messagebox.showwarning('warning', 'warning')
