Tkinter GUI with countdown

Posted on December 22, 2020April 6, 2022 By Luke K

Today I prepared something interesting. It is a GUI with countdown. See how does it work and try to analyze the code. Next modify it to gain new skills.

counter 3

counter

counter 1

counter done

Counter code

This is the code of tkinter countdown timer visible above.

import tkinter, time

root = tkinter.Tk()
root.title("Counter GUI")
countdown = 4
txt = "Counter "
bg = tkinter.Label(master=root, bg="black", fg="white", font="Arial 70", text="{0}{1}".format(txt, str(countdown)))
bg.pack()


def starting(ev):
    global txt, countdown
    if ev == "Enter":
        while countdown != 0:
            time.sleep(0.5)
            countdown -= 1
            bg["text"] = txt + str(countdown)
            bg.update()
            time.sleep(1)
        bg["text"] = "Done!"


root.bind("Space", starting(ev="Enter"))
root.mainloop()

I created a simple Tkinter label.
Then starting function with the iteration countdown. Feel free to use that 😉
