如下所示:

#先下载psutil库:pip install psutil
import psutil
import os,datetime,time

def getMemCpu():
 data = psutil.virtual_memory()
 total = data.total #总内存,单位为byte
 free = data.available #可以内存
 memory = "Memory usage:%d"%(int(round(data.percent)))+"%"+" "
 cpu = "CPU:%0.2f"%psutil.cpu_percent(interval=1)+"%"
 return memory+cpu

def main():

 while(True):
  info = getMemCpu()
  time.sleep(0.2)
  print info+"\b"*(len(info)+1),

if __name__=="__main__":
 main()
