采用python實現簡單QQ單用戶機器人的方法如下：

一、首先我們查看一下關于3GQQ的相關協議：
    對此，打開一個支持WAP的瀏覽器，可以使用Firefox的wmlbrowser插件，打開FF后，訪問地址 https://addons.mozilla.org/zh-CN/firefox/search/?q=wmlbrowser&cat=all&x=17&y=11
  
二、進入3GQQ的進行協議分析
    3GQQ的地址是：http://pt.3g.qq.com/s?aid=nLogin3gqq 用安裝了wmlbrowser插件的FF打開頁面后，啟用firebug，即可實現監視提交的數據。

三、源代碼部分：
