【基于Python制作三款起床闹钟的示例代码】嗨！大家有没有生物钟不准时的时候，是不是每到休息日或者长假就会经常要倒时差？
每天上班最痛苦的事情就是早起早起早起！这是大部分上班族的痛苦，但是不上班又是不可能的啦，因为都是为了搞钱
今天小编就用代码示例化，给大家展示一下不同的时钟，希望大家按时上班，按时搞钱啦

一、Turtle绘制时钟

二、Turtle实现模拟时钟 1）代码展示
基本思路：自定义shape，画出时针、分针、秒针。通过register_shape()函数。指针的位置通过shape类setheading()函数进行设置。获取系统时间作为当前时间，datetime.today()。利用ontimer()函数定义定时器事件，触发屏幕更新。利用write()函数在屏幕上显示文本。
