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。
