在微信好友信息抓取这一块，这才是最好的python分析技巧！

早些日子有人问我我的微信里面有一共多少朋友，我就随后拉倒了通讯录最下面就找到了微信一共有多少位好友。然后他又问我，这里面你认识多少人？

以下的代码内容只涉及一些简单的Python知识，稍微有一点Python知识的朋友都可以读下去。 如果你没有Python的知识你可能需要去学习一下Python，当然你也可以不用学，搭建好Python的环境就好，期间可能需要用到一些库需要自己去解决一下，在下文中也会详细诉述。

第一步：首先抓取微信朋友的资料

既然是要做统计和分析，第一步就是微信朋友的所有可以抓取的资料抓取出来。所谓有用的资料大致来说有以下几个内容：

那么如何抓取呢？这里使用了之前有一位大神写的如何找出被删的好友的代码，修改部分为从提取json数据截断，对返回的json数据进行提取分别找到了以下的所需要的信息：

在微信好友信息抓取这一块，这才是最好的python分析技巧！

昵称、微信号、城市、性别、星标好友、头像、个性签名、备注。提取以上信息，对头像图片进行下载，并对数据进行简单的清洗等等，最后一列为微信号不方便显示。

第二步：性别统计和地区分布

使用python的pandas科学计算库进行简单的统计，如果你没有用过，可以转至如下链接进行安装学习：【原】十分钟搞定pandas

只要掌握了非常简单的pandas只是就可以继续往下看做以下统计

（1）、所有好友的男女比例

（2）、所有好友的城市分布

（3）、统计认识的朋友以及占所有朋友的百分比

统计方法：所有朋友 - 没有备注的朋友 - 备注与昵称相同的朋友

（4）、统计认识的朋友中的男女比例

统计方法：对三的结果再进行男女划分即可得到结果

最后运用opencv的图像识别进行人像识别，统计微信好友中用人像作为头像的好友人数。OpenCV的全称是：Open Source Computer Vision Library。OpenCV是一个基于BSD许可（开源）发行的跨平台计算机视觉库，可以运行在Linux、Windows和Mac OS操作系统上。它轻量级而且高效——由一系列 C 函数和少量 C++ 类构成，同时提供了Python、Ruby、MATLAB等语言的接口，实现了图像处理和计算机视觉方面的很多通用算法。

执行以上代码统计出最后的结果

使用人像做头像的好友：59 因此不使用人像的1133，看来使用人像的人还是很少的。

运行提取人像头像的代码最后提取出的头像如下所示 ，不得不说Python的库真是十分的有用。（因为涉及到隐私，所以这里不会展示过多的头像）

最近仍然在研究签名以及头像的可用之处，也是欢迎大家一起学习交流。同时希望以上的内容可以提升一下大家的学习兴趣。关于微信好友的更多挖掘会不断进行。

（1）、人像头像与年龄之间的关系（由于微信没有年龄，于是想通过知乎进行推算）

（2）、个性签名与年龄性格之间的关系

（3）、微信号中所包含信息推算年龄层次，预测当前微信号年龄
