如何在Kivy中创建60秒倒数计时器

Question

我需要在猕猴桃中创建一个60秒的倒数计时器。它将在代码运行时立即开始，并且当倒数为0时应显示“倒数完成”。

尚未能够为此导出任何代码。我只需要一个简单的60秒倒数计时器

这是使用Tkinter开发的，

from tkinter import *
import time, sys
window = Tk()
window.title("Countdown")
print('\nHello\nInstructions: add time.\n')
hourz = input('Hours: ')
minz = input('Minutes: ')
secz = input('Seconds: ')
hour = int(hourz); min = int(minz); sec = int(secz)
var = StringVar()
var.set("00:00:00")
label_title = Label(window, textvariable=var)
label_title.pack()
window.update()
print('Check the window !\n')
while hour > -1:
    while min > -1:
        while sec > 0:
            sec = sec - 1
            time.sleep(1)
            sec1 = ('%02.f' % sec)  # format
            min1 = ('%02.f' % min)
            hour1 = ('%02.f' % hour)
            var.set('\r' + str(hour1) + ' : ' + str(min1) + ' : ' + str(sec1))
            window.update()
        min = min - 1
        sec = 60
    hour = hour - 1
    min = 59
print(' Finish !\n')
window.mainloop()
