抽奖系统（基于Tkinter）

一、抽奖规则及使用方法

抽奖规则： 从1-138个号码中随机抽奖，共进行n轮抽奖，每个号码仅有一次中奖机会，即已中奖的号码不会再次中奖。
使用方法： 要求开始抽奖后屏幕上随机滚动显示中奖号码，点击"STOP"之后，滚动停止，此时所显示的号码为本轮中奖号码；点击"清空内容"后方可再次抽奖。

二、实现代码

from tkinter import *

import numpy as np
from PIL import Image, ImageTk
import random
import pandas as pd
from time import sleep
import threading#线程

class Application():

    def __init__(self,app=None):
        self.app=app
        self.application()
        self.n=0#执行次数
        self.flag=True
    def application(self):
        #农行logo
        self.image=Image.open('abc300.png')
        self.abc_logo=ImageTk.PhotoImage(self.image)
        self.label0=Label(self.app,image=self.abc_logo)
        self.label0.pack()
        # 抽奖系统
        self.label1 = Label(self.app, text='抽奖系统', font=('黑体', 30), bg='white').pack()

        #开始抽奖按钮
        global number_pool
