24点小游戏 socket

为完成课程设计写的比较糙
仅实现基本要求

题目
24点游戏是一种使用扑克牌来进行的益智类游戏。游戏内容是从一
副扑克牌中抽去大小王剩下52张，任意抽取4张牌，把牌面上的数运
用加、减、乘、除和括号等进行运算得出24。每张牌都必须使用一
次，但不能重复使用,在本设计题目中，可以只选取在1-9这九张牌中
随机取牌，降低软件开发的难度。

大概流程

client发起连接

client发送密码

client收到状态码 并产生四个数等待玩家输入表达式 计算分值

client发送分值

client 显示排行榜和本次成绩

server监听端口

server等待接收用户名密码

server端验证账户名密码 并返回状态

server端等待分值数据

收到后判断是否比原来的分值大 如果大就更新 并返回排行榜

server关闭socket连接 和 mysql连接

环境

数据库使用mysql
语言python3

数据库表结构

Field	Type	Null	Key	Default	Extra
username	char(10)	YES		NULL
passwd	char(10)	YES		NULL
score	int(10)	YES		NULL

代码

比较简单详细说了
