Python GUI库最常用三种：
1.tkInter
这是 Python 做的 tk/tcl 的壳。python官方标准库，支持多平台。但界面比较初级和基本，基本不商用。使用参考：https://blog.csdn.net/laizhenghong2012/article/details/78988500，
布局：https://blog.csdn.net/qq_25600055/article/details/47061295
使用参考：http://www.runoob.com/python/python-gui-tkinter.html
2.wxPython
推荐，优秀GUI库，wxPython是作为优秀的跨平台GUI库wxWidgets的Python封装和Python模块的方式提供给用户的。支持win，unix，linux。
安装：
Cmd下直接执行：pip install wxPython
一般不成功，到https://pypi.org/project/wxPython/#files进行下载，注意python版本号对应包。
安装参考：https://blog.csdn.net/xiongwanfeng/article/details/77995055
本地包安装：pip install wxPython-4.0.2-cp36-cp36m-win32.whl
注：whl格式本质上是一个压缩包，其中包含py文件，以及编译过的pyd文件
程序出现错误：AttributeError: module 'wx' has no attribute 'Frame'，发现是文件名为wx，与模块重名了，改名就解决了。
安装过程：
