基于python+tkinter的学生成绩信息管理系统

系统设计

2.开发工具
开发语言：python3.6.8
开发工具：JetBrains PyCharm 2019.1.2 x64
使用三方模块：os、tkinter、ttkbootstrap、messagebox、datetime、tkinter.ttk

3.系统展示
（1）登录界面

（2）管理界面

4.程序设计
Stu_login.py实现系统登录
Maingui.py 实现系统管理
studetailgui.py实现学生添加、修改、查看功能
changegui.py 实现用户权限，用户信息添加、密码修改
img存储程序需要的背景文件
data存储系统数据

5.Stu_login.py系统登录的实现
