Python :: 嵌套 JSON 导致 Spotify

Question

我很难在 Spotify search endpoint 中获得曲目 ID。

嵌套很深。

所以，如果我这样做：

 results = sp.search(q='artist:' + 'Nirvava + ' track:' + 'Milk it', type='track')
 pprint.pprint(results)

我能得到：

{u'tracks': {u'href': u'https://api.spotify.com/v1/search?query=artist%3ANirvana+track%3AMilk+it&type=track&offset=0&limit=10',
             u'items': [{u'album': {u'album_type': u'album',

       ----->            u'uri':u'spotify:track:4rtZtLpriBscg7zta3TZxp'},

问题：

现在，如何获取名称 'Milk It' 下的最后一个 'uri'（u'uri': u'spotify:track:4rtZtLpriBscg7zta3TZxp'}？

Answer 1

>>> print results['tracks']['items'][0]['uri']
spotify:track:4rtZtLpriBscg7zta3TZxp
