设计思路：
刚开始只是写着玩玩，后来发现这时钟挺有意思，没多想就扩展了许多功能。顺便学了一下多线程，
其实只要打好基础，这个真的很简单～（甲鱼哥的教程是真的用心，节奏快，干货多 ）
未来前景：
加上时钟表盘，优化多线程，完善计时器
程序解释：
首先介绍一下新加的渐变色效果：
- def make_it_more_beautiful():
- # 矩形属性
- rect = canvas.create_rectangle(10, 10, 580, 350, outline='red', width=40)
- # RGB颜色循环
- r, g, b = 255, 0, 0 # 初始颜色为红色
- while True:
- # 每0.1秒更新一次颜色
- time.sleep(0.1)
- # RGB颜色渐变
- r = (r - 1) % 256
- g = (g + 2) % 256
- b = (b + 1) % 256
- # 更新矩形颜色
- canvas.itemconfig(rect, outline=f'#{r:02x}{g:02x}{b:02x}')
就是画一个初始边缘颜色为红的矩形，每 0.1 秒变一次色，但并不是总丝滑
运行结束会有 RuntimeError，不用理？
因为tkinter其实不太支持多线程，而after有时出错！
最后是完整代码，想试一下的记得准备音乐
