python实现数据爬取-清洗-持久化存储-数据平台可视化
基于python对淘宝模特个人信息进行筛选爬取，数据清洗，持久化写入mysql数据库.使用django对数据库中的数据信息筛选并生成可视化报表进行分析。
数据爬取，筛选，存库：

动态数据展示
网站首页：
提交的信息会写入数据库中：
模特年龄正态分布情况：
首先对信息进行分词处理，然后排序，选取出现频率最高的前100个词。
这个花了我很多时间，要解决echarts地图只精确到省或者直辖市，而我爬取到的数据可能是具体的某一个地方市名，针对这个问题：我首先找了一下各省下面的市都有哪些，sql语句使用正则匹配想要获取的信息。我创建了个字典存放省名和下属的市名。另外创建个字典存放省名和匹配到的人数。
简单小结：这里面涉及到的知识点还挺多的：
爬虫：我使用的requests和beautiful这俩库。
数据库：使用的是mysql，涉及到数据库编码，sql查询，模糊匹配，python对数据库的操作，中文显示乱码的问题。
词云：jieba进行分词，pytagcloud用来生成词云。
django：views、templates、static 、url，因为我用的MySQLdb，所以没有使用django自身的ORM(models)，这样我觉得更灵活。
前端展示：bootstrap（主要用来做网站的布局）和echarts（进行图表展示和数据分析用）。
