How to obtain computer hardware information and status using Python

This article describes how to obtain computer hardware information and status using Python. it is a very practical technique, for more information about how to use Python to obtain computer hardware information and status, see the following example. Share it with you for your reference. The specific method is as follows:

The main function code is as follows:

#!/usr/bin/env python# encoding: utf-8from optparse import OptionParserimport osimport reimport jsondef 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:    returnif __name__ =="__main__":  main()
