I wrote the below code

    def simple_validator(namespace):
        if namespace.public_ip_address:
            is_list = isinstance(namespace.public_ip_address, list)
            def _validate_name_or_id(public_ip):
                is_id = is_valid_resource_id(public_ip)
                return (public_ip if is_id else resource_id(subscription=get_subscription_id(), resource_group=namespace.resource_group_name, namespace='Microsoft.Network', type='publicIPAddresses', name=public_ip))
            if is_list:
                for (i, public_ip) in enumerate(namespace.public_ip_address):
                    namespace.public_ip_address[i] = _validate_name_or_id(public_ip)
            else:
                namespace.public_ip_address = _validate_name_or_id(namespace.public_ip_address)
    def complex_validator_with_type(namespace):
        get_folded_parameter_validator('public_ip_address', 'Microsoft.Network/publicIPAddresses', '--public-ip-address', allow_none=allow_none, allow_new=allow_new, default_none=default_none)(namespace)
    return (complex_validator_with_type if has_type_field else simple_validator)

What's a good function header?
