PythonStudio：国人开发的python窗体IDE，学生管理系统
国人开发的python窗体设计IDE，详情请看：PythonStudio：一款国人写的python及窗口开发编辑IDE，可以替代pyqt designer等设计器了-CSDN博客
这个软件作者还录制了入门的教程，跟着视频做，是个不错的python视频教程呢。从软件的使用，窗体的设计，到python的学习， 对小白来说很友好啊。
最最最主要的，这个软件自带很多皮肤，漂亮的皮肤。
我跟着教程做这个学生信息管理系统，感觉使用它来做python窗口软件程序，真的很方便快捷。

# 显示全部学生信息本来还有排序和显示2个窗体的，我没有做。我使用的是皮肤 Windows10 Malibu。
self.sm = StyleManager()
self.sm.LoadFromFile("Windows10Malibu.vsf")
self.sm.SetStyle('Windows10 Malibu')3行代码，加个123kb的文件，就给几个窗口都换了皮肤了，真的方便啊。
