I wrote the below code

    extra_hook = kwargs.pop('extra_hook', None)
    config = _GetConfigFromKwargs(kwargs)
    (keys, multiple) = NormalizeAndTypeCheckKeys(keys)
    def local_extra_hook(entities):
        if multiple:
            result = entities
        else:
            if (entities[0] is None):
                raise datastore_errors.EntityNotFoundError()
            result = entities[0]
        if extra_hook:
            return extra_hook(result)
        return result
    return _GetConnection().async_get(config, keys, local_extra_hook)
