国庆假期快到了，想查查还有几天几小时到假期，这对程序员小菜一碟，轻轻松松用python写个倒计时程序（天、时、分、秒），助你熬到假期！

一、先看效果：

二、安装python：

1、下载安装python

下载安装python3.9.6，进入python官方网站：http://www.python.org/

点击Python 3.9.6

直接安装即可。

2、验证安装成功。

按win+R输入cmd，打开控制台，输入python -V，输出python版本号说明安装成功。

三、代码

##import library
from tkinter import *
import time
from datetime import datetime,timedelta

################GUI to display window ##########################
root = Tk()

  day=0
  if hour>24:
    day,hour=(hour//24,hour%24) 

  sec.set(second)
  mins.set(minute)
  hrs.set(hour)
  days.set(day)
  root.update()
  time.sleep(1)

  times -= 1

Button(root, text='START', bd ='5', command = countdown, bg = 'antique white', font = 'arial 10 bold').place(x=150, y=210)
root.mainloop()

四、运行

打开工程文件，在地址栏里输入cmd，按Enter回车，即打开控制台。

输入python main.py，按回车就打开了程序GUI界面。

到达时间填2021年10月1日，按start按钮，就开始放假倒计时啦！
