此篇文章参考微信通信机制，收益匪浅！：http://lib.csdn.net/article/wechat/63831

QQ交流群127591054

当然也可以写发送消息的代码，机制和上述文章介绍的一样，大家可以参考学习！

偶遇：偶尔在论坛发现有外国友人在开源社区发布的Python微信删除好友查看，但是这个作者的代码我这边运行出现了点问题，就是各种问题，我在作者基础上进行研究修改！最终在Python2.7成功运行，之后又用了两天时间把运行环境转移到Python3.5。几乎完美执行！但是有一个问题我真的无能为力！在当我输出第三组好友名单的时候，就报错了！

报错如下：没办法我就去掉输出好友，就正常了，完整代码在下面，几乎每一句做了详细的注释！

#UnicodeEncodeError: 'UCS-2' codec can't encode characters in position 138-138: Non-BMP character not supported in Tk

原理：简单点就是把好友分组拉入群组，不超过40，别人是看不到的，拉不进俩就代表你被删了！！

但是问题来了，我最近发现腾讯web端操作容易被受限制，我拉了一组或者两组就被限制，说操作频繁了！！所以大家可以拿来学习微信通讯机制！！，不可以用来做坏事哦！虽然可以得到这个用户所有的信息！

完整代码如下：祝大家学习进步！详细注释代码中有写。^~^，就不一句一句讲了。
1、运行代码,会跳出二维码，扫描在手机确认登陆，然后关闭图片，程序自动运行！！

2、按操作一步一步执行就可以了~~，具体实现看注释其实不难。
