️国庆假期快到了,用python写个倒计时程序,助你熬到假期!️
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://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

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2022年10月1日,按start按钮,就开始放假倒计时啦!
