python实现的简单抽奖系统实例

本文实例讲述了python实现的简单抽奖系统。分享给大家供大家参考。具体实现方法如下：

#!/usr/bin/env python
#coding=utf-8
from Tkinter import *
import time
import random
class App:
 def __init__(self,master):
   frame = Frame(master)
   frame.pack()
   v = StringVar()
   self.e = Entry(frame,textvariable=v,bd='5')
   v.set('')
   self.v = v
   self.e.pack(padx=5)
   self.button1 = Button(frame,text = 'start',fg='red',command=self.start_hi)
   self.button1.pack(side=LEFT)
   self.button2 = Button(frame,text='stop',fg = 'blue',command=self.say_stop)
   self.button2.pack(side=LEFT)
   self.root=master
   self.stop = 0
   #scrollbar = Scrollbar(frame, orient=VERTICAL)
   #self.b1 = Listbox(frame, yscrollcommand=scrollbar.set)
   #scrollbar.pack(side=RIGHT, fill=Y)
   #self.b1.pack(side=LEFT, fill=BOTH, expand=1)
 def list_star(self):
   star = []
   file = open('yaojiang.txt','r+')
   data = file.readlines()
   file.close()
   for n in data:
     l1 = n.split(':')
     a = l1[0] + ':'+ l1[1][:4] + 'xxxx' + l1[1][8:12]
     a = a.strip()
     star.append(a)
   return star
 def start_hi(self):
   self.stop = 0
   #star = []
   #file = open('yaojiang.txt','r+')
   #data = file.readlines()
   #file.close()
   #for n in data:
     #l1 = n.split(':')
     #a = l1[0] + ':'+ l1[1][:4] + 'xxxx' + l1[1][8:12]
     #a = a.strip()
     #star.append(a)
   star = self.list_star()
   self.update_clock(star)
 def say_stop(self):
   self.stop = 1
   #b = self.start()
 def update_clock(self,star):
   b = random.choice(star)
   self.v.set(b)
   if self.stop == 1:
     return
     self.root.after(50, self.update_clock,star)
root = Tk()
app = App(root)
root.mainloop()
