python近日学习pyqt5相关知识

因为一门课程要结课，需要做出一个能传数据并储存的系统界面。思来想去最好是用python，但是对做界面一点都不熟悉，并且Python也只会一点点，因为我们专业并不是计算机，对编程学习稍微有限。此文章仅仅用来总结一些小知识。

对命令行，查看已安装的库用

pip list

看python的版本

python -V

将ui 文件转换成 py文件

pyuic5 -o [文件名].py [文件名].ui -x

可以不加-x，但是那样没有main，好像是没有实例化，不能单独运行。

今天突发奇想看能不能做成一个只是界面的exe文件使用如下代码

pyinstaller -F -w -i favicon.ico difficult6.py

想要什么图标，自己找一张ico图片下载下来放在与py文件相同的目录下

即可生成。做出来的东西是用qt designerb是自己一步一步做出来的

提供一下py代码
