Python: how to obtain computer hardware information and status.

This article demonstrates how to obtain computer hardware information and status by using Python as an example. It is a useful technique in Python programming. 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()

How can I use python to obtain webpage information?

Selenium. Or the front-end implementation ..

Or use a gui to display the html page. Then capture.
 
How to program C/C ++ to read all the hardware information of the computer

I just wrote the file system information. NTFS is printed (NTFS is used for my files). Different hardware uses different API functions.
I don't know much about this. This function is still checked online. You can go to the Internet to check which API functions are used to obtain the hardware information, and then go to MSDN.
GetSystemMetrics is the screen information.
# Include <iostream>
# Include <string>
# Include <windows. h>

Using namespace std;

Int main ()
{
DWORD dwSysFlags;
Char fileSysNameBuf [100];
Dword filesysnamebufsize = 100;
GetVolumeInformation ("c:/", NULL, 0, NULL, NULL,
& DwSysFlags, fileSysNameBuf,
FILESYSNAMEBUFSIZE );
Cout <fileSysNameBuf <endl;
Cout <GetSystemMetrics (SM_CXSCREEN) <endl;
Cout <GetSystemMetrics (SM_CYSCREEN) <endl;
Return 0;
}
