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()

希望本文所述对大家的Python程序设计有所帮助。
