小伙伴们，今天我们利用cursor不写一行代码开发一个电脑的系统状态监控小应用！
下载安装cursor：
网址：https://www.cursor.com/cn
下载后双击安装
输入提示词：
制作一个winswos应用，实现显示时间精确到秒，
显示cpu温度、cpu占用率,显示显卡GPU的温度和使用率，
内存的占用率，用户可自定义窗体界面大小，背景颜色，透明度，显示层级。
字体大小可调节。利用python pyqt5 实现
自动生成代码，选择：accept all
生成的代码 运行结果如下：
我们来进行优化：
优化功能，添加大核小核占用率，cpu gpu 相关数据未能正常读取。 界面优化 参考苹果IOS风格
期间如果遇到问题直接用自然语言提问给cursor,cursor会自动解决更新代码，经过几轮问答最终成果如下：
