Here is a short program that updates the title according to your code:

import time
from tkinter import *
def changeTitle(root, val, t):
    root.title(val)
    root.after(1000, lambda:countdown(t-1, root))
def countdown(t, root):
     if t+1:
         mins, secs = divmod(t, 60)
         timeformat = '{:02d}:{:02d}'.format(mins, secs)
         changeTitle(root, timeformat, t)
     else:
         return
root=Tk()
countdown(10, root)
mainloop()
