spinn3r からのデータを操作しようとしています。データは protobuf として返されます。Python で protobuf オブジェクトを出力すると、次のようになります。

print data

「feed_entry」オブジェクトから「作成者名」を抽出したい。私はこれを試しました：

print data.feed_entry.author.name

エラーが発生します：

AttributeError: 'RepeatedCompositeFieldContainer' object has no attribute 'name'

著者オブジェクトを印刷して、何が起こるかを確認してみました。これは私が得たものです：

print u.feed_entry.author
[<spinn3rApi_pb2.Author object at 0x362e6d0>]

この著者名を抽出するにはどうすればよいですか?

リストのようu.feed_entry.authorです。角かっこに注意してください。

[<spinn3rApi_pb2.Author object at 0x362e6d0>]

これで問題が解決するはずです（少なくとも1人の著者がいると仮定します）：

print data.feed_entry.author[0].name
