记录学习过程+代码
1搭建环境
安装pyqt5
在线安装
pip install pyqt5离线下载+安装
pip download pyqt5 -d save_pathpip install 安装QtDesigner
下载地址：Qt Designer Download for Windows and Mac
ui转python
pyuic5 -x mydesign.ui -o mydesign.py可以将QtDesigner ,pyuic5加入到pycharm，详见Python - PyQt6、QDesigner、pyuic5-tool 安装使用_sipbuild.pyproject.pyprojectoptionexception-CSDN博客
2.使用
