python系统监控及邮件发送
#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)

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

psutil.net_io_counters() #查看网络流量
