【Python + Mysql + UI】学生信息管理系统（附代码）

...........做了一个学生信息管理的简单数据库程序，写了一点简单的UI界面，功能不是很强大，代码组织也很不科学，洋洋洒洒竟然写了700多行.......分享出来，一起学习

**********************************/

创建数据库代码如下：

create database student_info_system;
use student_info_system
create table admin(username char(30),password char(30));
insert into admin values('admin','admin');
create table teacher_up(username char(30),password char(30));
create table student_up(username char(30), password char(30));insert into teacher_up values('admin','admin');
insert into student_upvalues('admin','admin');create table teacher_info(id bigint primary key,name char(10),gender char(2),age int,grade int);create table student_info(id bigint primary key,name char(30),gender char(2),age int,grade int);

其中teacher_up(teacher username & password)存放老师账户的用户名和密码，其他up结尾的同样。以_info为结尾的表存放老师或者学生信息。先给管理员账户添加了初始账户和密码(admin，admin)

然后是代码，需要先安装pymysql库，安装命令pip3 install pymysql

下面是带UI的学生信息管理代码，在Python3.6下调试通过。
