Python 基于tkinter模块的GUI可视化学生成绩管理系统实现（含文件保存）

作者：潇
版本：1.0
面向对象，带日志，带异常处理的，带密码加密
第一次执行会生成数据库和csv文件，以后添加的数据会自动保存到里面
删除数据库再次执行程序。会初始化数据库

管理员（超级账号，无法删除）
账户：admin 密码：’’（空输入的意思）
（为了调试方便，账号密码已经提前输入，直接点登录即可）

DataProcess是我自己写的一个数据保存模块，在本博文的第三部分，即完整代码下面，需要单独成一个py文件

1. 标准模块导入

from tkinter import *
from tkinter import messagebox
from tkinter import ttk
import time

2.完整代码

# _*_ coding:utf-8 _*_

@ 功能 : 本模块用于对窗口界面的定义
