python 爬取微信好友列表和个性签名，绘制个性签名云图

python爬取微信好友列表和个性签名，绘制个性签名云图

1. 简要介绍

本次实验主要用到下面几个库 ： 

 1）itchat---用于微信接口，实现生成QR码，用于微信扫描登陆

 2）re（正则化）---由于微信好友个性签名含有中英文，本次只提取中文，需要使用re模块去除其他无关字符

 3）wordcloud（云图）---使用该模块生成中文云图

 4）jieba（中文分词）--- 号称最好的中文分词工具

2. 安装库

pip install re
pip install jieba
pip install itchat
pip install wordcloud
