本文实例为大家分享了python实时监控cpu的工具，供大家参考，具体内容如下
虽然写的很不完善，但是当练手吧，对于实时监控cpu还是有点用处的，虽然android studio已经提供了一样的功能，但是能够记录并生成成本地csv文件还是比as多一个功能的。
结果图：
直接放源码：

return self.getInfo(result)

return [re.findall('(\d+)%', _result), re.findall('K\s(\d+)K', _result)]

MyFrame().Show()
app.MainLoop()
原理：
界面用wx做的，图形用pychartdir做的，命令用的是top命令，每次截取到的数据都生成一张临时图片，然后刷新到屏幕上，看起来就是实时数据监控的效果了，基本上BUG一大堆，也懒得改了。
