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
