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()

希望本文所述对大家Python程序设计的学习有所帮助。

以上就是Python获取电脑硬件信息及状态的实现方法。今天不走，明天即使跑也不一定跟得上。更多关于Python获取电脑硬件信息及状态的实现方法请关注haodaima.com其它相关文章！
