市场需求分析
技术类课程的供需旺盛。Python和Vue作为热门开发语言与框架，市场对系统性学习资源的需求显著提升。企业必须高效培养全栈人才，个人开发者则寻求灵活的学习路径，催生了结合这两种工艺的在线学习系统开发需求。就是在线教育行业近年来呈现爆发式增长，尤其
技术栈优势
Python+Django/Flask后端具备快速开发、数据处理能力强（如用户行为分析、课程推荐算法）的特点，适合处理视频流、用户管理等复杂逻辑。Vue.js前端框架的响应式特性能够优化视频播放、交互式编程环境等用户体验，同时支持组件化研发，便于维护和迭代。

二、文档学习资料：
三、模块截图：
四、开发技术：
(1)Python：Python是一种高级编程语言，在工程开发中，Python用作后端开发语言。
(2)Django：Django是一个开源的Python Web框架，提供了许多内置的功能，如用户认证、会话、模板引擎、表单处理等，使得项目能够快速地开发出功能完备的网站。
(3)Pymysql：pymysql是一个Python的MySQL数据库连接器，它提供了Python与MySQL数据库之间的连接、查询、插入、更新和删除等数据库操作。
(4)Vue.js：Vue.js是一个用于构建用户界面的JavaScript框架。Vue的核心库只关注视图层，不仅易于学习，而且容易与其他库或现有项目集成。
(5)Element UI：Element UI是Vue.js的一个组件库，它提供了一系列的Web组件，包括表格、表单、弹窗、导航栏等。能够帮助开发者快速构建出风格一致的页面。
(6)CSS3：CSS3是层叠样式表（CSS）的第三个版本，它在项目开发中用于控制HTML元素的呈现方式。CSS3加入了很多新特性，如动画、过渡、阴影等，使得网页的视觉效果更加丰富和细腻。
(7)MySQL 5.7：MySQL是一个开源的关系型数据库管理系统。版本5.7是MySQL的一个主要版本，它引入了诸如JSON数据类型、改进的查询优化器、多源复制等新特性。MySQL用于项目存储、检索和管理数据
