tkinter clock

[Ondrej]

Hello everyone,

I need help to make simple clock app which will change background color in choosen periods with duration for few secc and after then transform back. I created simple clock with tkinter, which you can see bellow, but I have problem with conditions of the changing of background color. I will appreciate any idea. thanks

import sys
from tkinter import *
import time

def tick():
    time_string=time.strftime("%H:%M:%S")
    clock.config(text=time_string)
    clock.after(200,tick)
    
root=Tk()
clock=Label(root, font=("times", 100, "bold"), bg="red")
clock.grid(row=0, column=1)
tick()
root.mainloop()
