How to make timer in tkinter window title?

Question

Python

Hello. I need to insert a countdown timer in the title of a window created with the tkinter library. So it's like this:

from tkinter import *

def countdown(t):
    pass

root = Tk()
root.title(countdown(60))
root.mainloop()

Where countdown(t) is a function that returns 1 less every second. Is this even possible?

Answer 1

from tkinter import *

root = Tk()
t = 60
def countdown():
    global t, root
    root.title(str(t))
    if t==0: root.destroy()
    t-=1
    root.after(1000, countdown)

countdown()
root.mainloop()
