【Python毕业设计】基于Python+Flask+MySQL的学生信息管理系统（附完整源码

休息状态 · 发表于 2023-4-18 21:13:08

1、项目说明
基于python+Flask+mysql的学生信息管理系统项目实战
项目需要安装pycharm专业版，mysql数据库以及项目所需的所有模块
创建数据库名称db_online_notes，然后执行sql文件生成数据表和数据
项目需要安装 flask,pymysql以及其他的一些模块
安装命令如下：
pip install -i https://pypi.tuna.tsinghua.edu.cn/simple 模块名称
如安装flask：pip install -i https://pypi.tuna.tsinghua.edu.cn/simple flask

2、项目主要技术
python编程技术
flask框架技术
mysql数据库技术
html编程
css编程
js编程

3、项目结构
static 项目静态文件存储文件夹（images,css,js）
templates 项目模板文件文件夹（html）
log.txt 错误日志存放文件
forms.py 表单验证对象
mysql_util.py 数据库链接操作
manage.py 项目功能业务逻辑实现（项目入口）

4、项目主要功能
用户登录注册
文章信息的增删改查
