项目编号：BS-Python-034

一，环境介绍

语言环境：Python3.8

数据库：Mysql: mysql5.7

WEB框架：Django

开发工具：IDEA或PyCharm

二，项目简介

基于Python实现的地方美食导游平台，旨在为用户提供一站式的美食探索与体验服务。该平台利用Python的Web开发框架（如Django或Flask），结合数据库技术（如SQLite、MySQL）存储地方特色美食信息、餐厅位置、用户评价等数据。用户可以通过该平台浏览不同地区的特色美食介绍、查看餐厅详细信息（包括地址、营业时间、联系方式）、阅读其他食客的评价与推荐，并可在线分享美食心得等数据信息。

此外，平台还集成了地图API（如Google Maps或高德地图），帮助用户直观查看美食地点分布，规划就餐路线。同时，设有智能推荐系统，根据用户的口味偏好和历史记录，推送个性化的美食建议。平台还支持用户提交自己的美食体验与图片分享，形成互动交流的社区氛围，增强用户粘性。整体而言，该平台通过丰富的功能与便捷的交互体验，让地方美食的探索与享受变得更加轻松愉悦。
