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()
