基于tkinter的随机抽奖程序（每天一个python小项目）

import csv
import tkinter as tk
import tkinter.messagebox
import datetime
import pandas as pd
import os

dt = datetime.datetime.now()
time = dt.strftime("%Y-%m-%d %H:%M:%S")
#保存参与抽奖的数据

  if flag:
     #打开文件
     with open('G:/code/079/data.csv', 'r',newline='') as f:
             #读取数据

                myval.append(int(row[3]))
                num = random.randint(0, 1000)

            writer.writerow([txt_name.get(),txt_tel.get(),time,num])     # 写入第一行数据
  tkinter.messagebox.showinfo("消息提示",'您的幸运码是：'+str(num))      #弹出消息提示框
#读取数据抽取幸运码
def read():

  sam = df.sample(3)
  tkinter.messagebox.showinfo("消息提示",'获奖幸运码：'+ str(sam.iloc[0,3]) +'、'+ str(sam.iloc[1,3]) +'、'+ str(sam.iloc[2,3])) 
  tkinter.messagebox.showinfo("消息提示",'获奖姓名：'+ str(sam.iloc[0,0]) +'、'+ str(sam.iloc[1,0]) +'、'+ str(sam.iloc[2,0]))
#建立主窗口window
window = tk.Tk()
#设置窗口标题栏名称
window.title('抽奖小程序')
#设置窗口的大小
window.geometry('600x390')
canvas = tk.Canvas(window, width=600, height=400)
image_file = tk.PhotoImage(file='G:/code/079/1.png')
image = canvas.create_image(320, 0, anchor='n', image=image_file)
canvas.pack(side='top')
# 在主窗口添加标签
l1 = tk.Label(window, text='姓    名：', font=('Arial', 12)).place(x=30, y=320)
l2=tk.Label(window, text='手机号：',font=('Arial', 12)).place(x=30, y=350)
# 在主窗口添加文本框
txt_name = tk.StringVar()
text1 = tk.Entry(window,textvariable=txt_name, show = None,width=45)
txt_tel= tk.StringVar()
text2 = tk.Entry(window,textvariable=txt_tel,show = None,width=45)
text1.place(x=100,y=320)
text2.place(x=100,y=350)
# 在主窗口添加命令按钮
button1 = tk.Button(window,width=10, height=3,text='点击参与',bg='tomato',command=save).place(x=430, y=310)
button2 = tk.Button(window,width=10, height=3,text='开奖',bg='orange',command=read).place(x=510, y=310)
# 主窗口循环显示
window.mainloop()

运行结果：
