Python使用tkinter实现小时钟效果

本文实例为大家分享了Python使用tkinter实现小时钟效果的具体代码，供大家参考，具体内容如下

自己又调试了一下，分享一下

# coding:utf-8
from tkinter import *
import math,time
def points():
for i in range(1,13):
x = 200 + 130*math.sin(2*math.pi*i/12)
y = 200 - 130*math.cos(2*math.pi*i/12)
canvas.create_text(x,y,text=i)

def createline(radius,line_width,rad):
global List
global i
List = []
x = 200+radius*math.sin(rad)
y = 200-radius*math.cos(rad)
i=canvas.create_line(200,200,x,y,width=line_width)
List.append(i)

root = Tk()
root.resizable(0,0)
canvas = Canvas(root,width=400,height=500,bd=0,highlightthickness=0)
canvas.pack()
canvas.create_oval(50,50,350,350)
points()

while 1:
tm=time.localtime()
t=time.asctime(tm)
t_hour=0
if tm.tm_hour<=12:
t_hour=tm_hour
else:
t_hour=tm.tm_hour-12
rad1=2*math.pi*(t_hour+tm.tm_min/60)/12
rad2=2*math.pi*(tm.tm_min+tm.tm_sec/60)/60
rad3=2*math.pi*tm.tm_sec/60
createline(50,6,rad1,)
createline(90,3,rad2)
createline(120,1,rad3)
l=canvas.create_text(170,450,text=t)
root.update()
time.sleep(1)
for item in List:
canvas.delete(item)
canvas.delete(l)

root.update()
mainloop()

效果
