Python获取电脑硬件信息及状态的实现方法

本文以实例形式展示了python获取电脑硬件信息及状态的实现方法，是python程序设计中很有实用价值的技巧。分享给大家供大家参考之用。具体方法如下：

主要功能代码如下：

#!/usr/bin/env python
# encoding: utf-8

from optparse import optionparser
import os
import re
import json

def main():
  try:
    parser = optionparser(usage="%prog [options]")
    reg_result=re.compile('\[(.*)\]')
    #add option
    parser.add_option("-m","--machine",action="store",type="string",dest="machine",help="the machine to be check")
    parser.add_option("-f","--file",action="store",type="string",dest="file",help="the file with machine list")
    parser.add_option("-n","--noah_path",action="store",type="string",dest="noah",help="the bns path or group")
    (options,args)=parser.parse_args()

    result=""
    if options.machine:
      options.machine=options.machine.replace(".baidu.com","")
      result=os.popen("meta-query entity host "+options.machine+" -f syssuit,memtotal,disktotal,cpufrequency,cpuphysicalcores,netidc,status -j").read()
    elif options.file:
      result=os.popen("meta-query entity host -f syssuit,memtotal,disktotal,cpufrequency,cpuphysicalcores,netidc,status -f "+options.file+" -j").read()
    elif options.noah:
      result=os.popen("get_instance_by_service "+options.noah+" |meta-query entity host -f syssuit,memtotal,disktotal,cpufrequency,cpuphysicalcores,netidc,status -f -j").read()
    else:
      return

    result=json.loads(result)
    print "%-*s%-*s%-*s%-*s%-*s%-*s"%(40,"name",10,"cpu",10,"memery",10,"disk",10,"idc",10,"status")
    for item in result:
      if item['values']['cpufrequency']!="null":
        item['values']['cpufrequency']=str(float(item['values']['cpufrequency'])/1000.0)[0:3]
      else:
        item['values']['cpufrequency']="0"
      item['values']['disktotal']=str(float(item['values']['disktotal'])/1000000000.0)[0:5]
      item['values']['memtotal']=str(float(item['values']['memtotal'])/1024/1000.0)[0:5]
      
      print "%-*s%-*s%-*s%-*s%-*s%-*s" % (40,item['name'],10,item['values']['cpufrequency']+" x"+item['values']['cpuphysicalcores'],10,item['values']['memtotal']+"g",10,item['values']['disktotal']+"t",10,item['values']['netidc'],10,item['values']['status'])
  except exception,e:
    return

if __name__ =="__main__":
  main()
