微信是腾讯于2011年1月21日推出的免费应用程序，为智能终端提供即时通讯服务。它是由张小龙领导的腾讯广州R&D中心产品团队打造的。随着互联网的快速发展和人们的需求，微信已经更新为2.6.2.31版，全民微信时代。村里的张阿姨和家里的老父亲都知道怎么用微信。

但是我们和朋友、亲戚、恋人聊天的时候，我估计大家都经历过，就是微信撤单功能里提到的，对方撤一条消息。

一个撤的消息，像一个秘密，让你迫切的想去发现；或者作为诱饵，瞬间激起你的浓厚兴趣。你想知道，那是什么样的句子？是对方无意中说出的真话，还是一句话发错了人？

总之，这次退赛的消息很振奋人心。这个时候，技术人员就该出去了。

参见Python微信召回消息的参考代码:

本文到此结束，但真心建议，如果是男女朋友，就不要用Python查了。有些事情比知道要好。亲身经历。
