使用pyqt构建桌面图形应用
使用python语言也是可以编写Windows桌面应用的（尽管python并没有那么适合搞这个，并且相较于部分语言，效率也较低，但是却能让只会python的小伙伴不用学习其他语言也可以做出自己的桌面应用）。
要使用python来编写桌面应用，可以使用的库特别的多，这其中最方便的就属pyqt了，因为pyqt是可以使用qt设计师来直接拖放组件的，能大大提高编程的效率。
使用流程
1、下载qt设计师软件，可以到官网下载，其他平台也能搜索到。
2、在qt设计师中拖放组件，设计成自己想要的样子之后，生成python代码，将代码复制到python IDE当中去，之后对代码进行修改即可。
