the script is working with this change

why have you used ms whereas us is used in the json file ?

• if not os.path.isfile(args.infile):

•    print 'ERROR: input file %s does not exist\n' %args.infile
  

•    parser.print_help()
  

•    sys.exit(2)
  

• doc = target = load_json_file(args.infile)
• if args.key:

•    if not target:
  

•        print 'ERROR: key id %s is not found' %args.key
