＜Python实际应用＞做一个简单的签到投屏系统

        公司接了个活，承办一个由团委组织的五四青年节徒步活动，其中一个环节是现场报名，来的人把名字填进去后随机分组，并显示在现场的LED大屏幕上，我自告奋勇用Python来开发这个小程序。这里记录一下

【项目需求】

1、报名录入姓名和赛程，数据传到LED大屏所在的电脑上

2、赛程分半程和全程,半程的又分为ABC三个路线，每个路线下面有若干个分组，全程下面也分6个组，要求签到以后把人员随机分组

3、在大屏幕上显示出来

【分析】

1、用tkinter做一个输入界面，用一个文本框让用户输入名字，然后用一个单选框让用户选择半程还是全程，然后数据用socket传给连接现场LED屏幕的电脑

2、写一个函数处理分组工作，根据接收到的全程还是半程信息，分别进行随机分组

3、写一个服务器端程序在连接LED的电脑上运行，显示界面，并把处理结果及时更新到大屏幕。

这包括三个部分：

a) 用tkinter做一个显示界面，包括全程和半程ABC的区分，这可以用frame来实现，然后下面再细分分组，可以用label和text来实现

b) 搭一个简单的服务器用socket接收来自客户端的信息

c) 写一个随机分组函数，写一个清除函数

【项目代码】

1、客户端代码，负责录入数据，上传到服务器，命名为client.py

import tkinter as tk
from tkinter import *root = Tk()
root.title('报名签到')
root.geometry('300x500')title1=Label(root,fg='blue',text='填入姓名',font=('华文新魏',12))
name=Entry(root,bg='white',width=20,font=('楷体',24))data_list=[]
def mychoice():global data_listval=var.get()if len(data_list)==0:data_list.append(val)else:data_list=[]data_list.append(val)return val
var = StringVar()
zubie_label=Label(root,fg='blue',text='选择赛程',font=('华文新魏',12))
zb1 = Radiobutton(root,text="全程",variable=var,value='q',command=mychoice)zb2 = Radiobutton(root,text="半程",variable=var,value='b',command=mychoice)var.set(0)def tijiao():global data_listif len(data_list)==0:print('未选择赛程')else:if name.get():data_list.append(name.get())print(data_list)data_str=",".join(data_list)msg=data_strprint(msg)# 导入 socket、sys 模块import socket# 创建 socket 对象s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)# 获取本地主机名#host = socket.gethostname()host = '*.*.*.*' #替换成服务器IP地址# 设置端口号port = 9999# 连接服务，指定主机和端口s.connect((host, port))s.send(msg.encode('utf-8'))data = s.recv(1024)print(data.decode("utf8"))s.close()data_list=[]name.delete(0,END)else:print('未填写姓名')btn1=Button(root,fg='blue',text='提交',command=tijiao)title1.place(relx=0.25,rely=0.25,height=30,width=120)
name.place(relx=0.3,rely=0.35,height=30,width=100)
zubie_label.place(relx=0.3,rely=0.45,height=30,width=100)
zb1.place(relx=0.5,rely=0.55,height=30,width=100)
zb2.place(relx=0.7,rely=0.55,height=30,width=100)btn1.place(relx=0.3,rely=0.65,height=30,width=80)root.mainloop()

2、服务器端代码,实现接收信息，处理分组，并在大屏幕显示，命名为server.py

【运行效果】

在连接LED大屏幕的电脑上启动server.py,大屏幕上界面如下：

 然后在签到电脑上启动client.py,界面如下

 开始使用， 比如我们在文本框中填入 欧阳锋，选择全程，点击提交，然后就会在大屏幕上看到：

 继续，填郭靖，选半程，提交：

OK，实测可用
