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

    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()

    else:

  except Exception,e: 
    return
  
if  __name__ =="__main__": 
  main()
