#psutil模块是一个跨平台库，能轻松实现获取系统运行的进程和系统利用率

 

import psutil                                    #先导入psutil模块

 res = psutil.cpu_percent(1)              #1s内cpu的使用率

 print(res)

 

 res1 = psutil.cpu_percent(1,True)    #每一秒cpu的占用率

 print(res1)

 

 res2 = psutil.virtual_memory()          #内存使用率

 print(res2)

 print( \'%.2f%%\' %res2[2])              #以百分比形式打印第三位

 

 res4 = psutil.disk_usage(\'C:\')            #硬盘分区的使用率

 print(res4)

 

 res5 = psutil.net_io_counters()       #查看网络流量

 print(res5)
