[Tkinter] DUAL WINDOWS...

[ATARI_LIVE]

Umm.. Thank for that but my point is the text did not print on both.
I am using Raspberry Pi 4B 4GB
I changed the text see here.

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="HELLO WORLD FROM LEFT", font=("Droid Sans Fallback", 30), fg="White", bg="black")
Label(window_right, text="HELLO WORLD FROM RIGHT", font=("Droid Sans Fallback", 30), fg="White", bg="black")
 
window_right.mainloop()
window_left.mainloop()

Oh Doh me.... forgot add label name and pack()... now it's worked.
