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()
