嘿嘿，我需要帮助从使用 Spotipy 调用 Spotify API 中获取正确信息。我对 Python 比较陌生，所以也许我遗漏了一些非常明显的东西，但我已经研究了几个小时并尝试了我能想到的一切，但仍然没有得到我想要的结果。我基本上想向 Spotify 询问用户保存的库，并从响应中取出曲目标题和艺术家并将它们保存以备后用。目前当我打电话时

tracks_response = spotify.current_user_saved_tracks(limit=1, offset=0)
print(tracks_response)

我收到这样的东西：

我认为这是一本普通的字典，所以我可以很容易地通过使用普通的字典语法来获得艺术家，比如

 print(tracks_response['items']['track']['artists']['name'])

但是当我打电话时，我收到一个错误报告：

 TypeError: list indices must be integers or slices, not str

但是，如果我将呼叫更改为：

 print(tracks_response['items'])

我得到：

 [{'added_at': '2018-05-31T18:59:42Z', 'track': {'album': {'album_type': 
 'album', 'artists': [{'external_urls': {'spotify': 
 'https://open.spotify.com/artist/4AA8eXtzqh5ykxtafLaPOi'}, 'href': 
 'https://api.spotify.com/v1/artists/4AA8eXtzqh5ykxtafLaPOi', 'id': 
 '4AA8eXtzqh5ykxtafLaPOi', 'name': 'What So Not',...

这与上面的内容相同，但从“项目”键开始......看来字典的其余部分是其中包含键值对的列表，我将如何从它们中获取我想要的数据？

任何帮助表示赞赏，谢谢。

实际上tracks_response['items']返回一个数组。仔细查看响应。您必须迭代项目列表才能获得“跟踪”对象。如果您需要从艺术家列表中打印每个艺术家的姓名，代码将是，

for item in tracks_response['items']:
    for artist in item['track']['album']['artists']:
         print(artist['name'])
