[Tkinter] DUAL WINDOWS...

[DT2000]

This is an example of what deanhystad is stating on using Toplevel() however in this example closing the main Tk() window (window_left) all windows close also.

from tkinter import *

window_left = Tk()
window_left.geometry("300x300")
window_left.configure(bg='black')
window_left.title("LEFT")

window_right = Toplevel()
window_right.geometry("300x300")
window_right.configure(bg='black')
window_right.title("RIGHT")

Label(window_left, text="left", fg="White")
Label(window_right, text="right", fg="White")

window_right.mainloop()
window_left.mainloop()
