学生管理系统-Python tkinter图形化界面+sqlserver+柱状图

参考了大佬的，把mysql数据库改成了sqlserver

附上大佬的代码链接

程序我都写到了一个.py文件中，之前做的课程作业，现在看起来有点凌乱，

需要先在sqlserver中新建一个XSCJ数据库，里面有两张表，一个student表，一个teacher表

创建表的语句在程序的开头，我注释掉了，先取消掉那个注释，创建完再注释掉就可以了

前两张图片是背景图片，必须用gif格式的（我也不知为什么），还有一个图标ico格式的，网上随便找一个

这是主界面，可以注册和选择角色登录

学生的功能仅有查询自己的成绩和修改密码，老师拥有所有权限

学生的功能就不演示了，直接上教师的功能。

一、这是显示所有学生信息

二、添加学生信息直接输入在上面的文本框，点击添加就可以了

三、删除学生信息，选中表格中的数据，点删除即可，

四、修改学生信息

五、查询学生信息，可用两种查询方式，学号和姓名都可单独查询

六、统计学生信息，可现实最高分、最低分、平均分、及格等的统计

点击柱形图即可统计

我的源代码如下，执行如果出错请先检查数据库，图片要和源程序放在同一路径下
