实践项目三：桌面版python 获取未来七天的天气情况（2）

         做项目一的时候，了解到了qt可以做界面，在做项目二的时候，想着把它做成像界面一一样的桌面程序，打包后可以发给小伙伴用，初步实现查询功能，界面有些简陋，会继续完善更新博客。

 打包方法在项目一最后有：打包方法

            我把打包后的可直接下载的exe文件传到csdn资源库，有兴趣的可以下载：

    运行界面：

     

     完善：

               1.输入拼音不方便，实现输入汉字

               2.查询内容增加

               3.界面增加图片

     源码：
