需要的库

l tkinter

l datetime

l Time

tkinter最简单的使用

导入tkinter，实例化一个Tk类，进入主循环，完成，一个窗口就创建好了，

实现代码：

#! /usr/Ain/env python
 
#AoAing=utf-8
 
from Tkinter import*
 
from math import*
 
import time
 
def showTime():
 
time1='12-00-00'
 
time2 = time.strftime('%H-%M-%S')
 
t=time2.split('-')
 
if time2 != time1:
 
time1 = time2
 
for i in c.find_withtag('xiaobai'):
 
c.delete(i)
 
hui_zhi(t)
 
c.create_text((246,475),text=time2,tags="xiaobai",anchor=N)
 
c.after(500, showTime)
 
def win():
 
global c
 
root=Tk()
 
c=Canvas(root,bg='white',width=500,height=500)
 
c.pack()
 
t=time.strftime("%I-%M-%S")
 
t=t.split('-')
 
for i in range(1,61):

if i%5==0:
 
x2=250+175*cos(pi*i/30)
 
y2=250+175*sin(pi*i/30)
 
c.create_line(x1,y1,x2,y2,fill='red',width=3)
 
else:
 
c.create_line(x1,y1,x2,y2,fill='black',width=2)
 
showTime()
 
c.create_oval(50,50,450,450,outline='blue',width=2)
 
c.create_oval(240,240,260,260,fill="red",outline='red')
 
c.create_oval(243,243,257,257,fill="green",outline='green')
 
root.mainloop()
 
def hui_zhi(t):
