项目编号：BS-Python-054

一，环境介绍

语言环境：Python3.8
数据库：Mysql: mysql5.7
WEB框架：Django
爬虫：Scrapy
开发工具：IDEA或PyCharm
二，项目简介

本系统基于Python网络爬虫技术，旨在自动化收集各大电商平台上的电子产品信息，并通过数据可视化手段直观展示给用户。系统首先利用Python的爬虫框架（如Scrapy、Requests等）访问指定网站，抓取电子产品（如手机、电脑、相机等）的详细参数、价格、用户评价等关键数据。随后，利用数据处理库（如Pandas）对数据进行清洗、整理与存储。最后，通过数据可视化工具（如Matplotlib、Seaborn、Plotly或Echarts等）生成交互式图表和报告，直观展示电子产品的价格趋势、用户评分分布、热销产品排名等，帮助用户快速了解市场动态，做出更加明智的购买决策。整个系统实现了从数据抓取到分析展示的全链条自动化，提升了信息获取的效率和准确性。
