[Py] Countdown counter

Here is a countdown counter which counts down in HH:MM:SS format. The original example has given by vegaseat, which counts increasingly. I modified it to be a countdown version as the follows.

A ``countdown'' counter using Tkinter
Original version has given by vegaseat 17aug2007

This version is modified from the original one
by thk 2010/06/05

import Tkinter as tk
from itertools import count

def start_counter_down(label):
counter = count(0)
begin_time = 10 # sec.
def update_func():
left_time = begin_time -
show_hr = left_time/3600
show_min = (left_time%3600)/60
show_sec = (left_time%3660)%60
label.after(1000, update_func) # 1000ms
if left_time <= 0: label.config(text="Time's up!") update_func() root = tk.Tk() root.title("Counting Down") label = tk.Label(root, fg="red") label.pack() start_counter_down(label) button = tk.Button(root, text='Stop & Quit', width=30, command=root.destroy) button.pack() root.mainloop()
