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。
