前两天看到一篇关于Python使用Tkinter 的博文，写的很好。就拿来研究了一下，改了改。现分享如下：

天气插件： 使用json接受中气象的本地信息，显示使用tkinter

show_in_tkinter(101180308)本来设计的是可以输入城市代码，来实时的获取对应的天气信息，并更新到界面上的，但是不知道为什么系统会默认新开一个Tkinter的界面，导致刷新失败！
有时间再来更新本文，打个时间戳:2016年8月26日22:50:14
再分享一下我老师大神的人工智能教程吧。零基础！通俗易懂！风趣幽默！还带黄段子！希望你也加入到我们人工智能的队伍中来！https://blog.csdn.net/jiangjunshow
