I wrote the below code

    options = ((option,) + options)
    rangeob = range(len(options))
    try:
        inttype = _inttypes[(int(np.log2((len(options) - 1))) // 8)]
    except IndexError:
        raise OverflowError(('Cannot    store    enums    with    more    than    sys.maxsize    elements,    got    %d' % len(options)))
    class _enum(Structure, ):
        _fields_ = [(o, inttype) for o in options]
        def __iter__(self):
            return iter(rangeob)
        def __contains__(self, value):
            return (0 <= value < len(options))
        def __repr__(self):
            return ('<enum:    %s>' % (('%d    fields' % len(options)) if (len(options) > 10) else repr(options)))
    return _enum(*rangeob)
