def _normalize(d):
    '''
    The above parse function generates output of list in dict form
    i.e. {'abc' : {0: 'xyz', 1: 'pqr'}}. This function normalize it and turn
    them into proper data type, i.e. {'abc': ['xyz', 'pqr']}

    Note: if dict has element starts with 10, 11 etc.. this function won't fill
    blanks.
    for eg: {'abc': {10: 'xyz', 12: 'pqr'}} will convert to 
    {'abc': ['xyz', 'pqr']}
