使用Spotipy中来自sp.albums的.json输出，从同一位艺术家的多张专辑中获取曲目ID

如何解决使用Spotipy中来自sp.albums的.json输出，从同一位艺术家的多张专辑中获取曲目ID

我知道有多种方法可以做到这一点-而且我已经使用用户播放列表唱片从一位艺术家那里成功获取了所有曲目ID。但我想提出一个不依赖于现有用户播放列表的Python程序。

我想做的是从将多个专辑传递到Spotipy中的sp.albums时创建的.json文件中的专辑数据中提取曲目ID。

我有我要传递给唱片专辑的这张专辑ID列表，这些列表ID是我最喜欢的乐队之一Fugazi的所有唱片。

 album_ids = ['6ZyP2KPr2AkAbUWbsHmzEg','2bU6BaHfovn3rvxxxHSkWd','3tnzZhTTjRTExYc9odG0dt','1hatewdVYKH0xqEkdOLQLb','3kPxFCpws7ZyzI1cMME4dV','3zBQ2UZzCzgCnIkFYMOWlY','3QpmoxpWCacHLsZMhLn1ag','3ZnF1cPxlqB48RyLiecDnv','21wERoyBas2JCRCgysPDJX']

然后我将此列表传递给sp.albums：

fugazi_songs = sp.albums(album_ids)

fugazi_songs的.json文件太长了，无法在此处发布。

但这是一开始的代码，其中包含第一张专辑中第一首歌曲的数据：

解析fugazi_songs .json文件会向我显示指向单个轨道ID的层次结构：

albums.item.tracks.items.item.artists.item.id

我正在使用for循环尝试使用此路径从.json文件中的每首歌曲中获取所有曲目ID。

track_ids = []
for i in range(len(fugazi_songs['albums'])):
track_ids.append(fugazi_songs['albums'][i]['tracks']['items'][i]['id'])

输出仅给我一张专辑的track_id。

track_ids
['4PKl6Tt8YQaJIJmlnwELi7','44ETQCGE31ypmEc5ut3WMe','18CrxbPSUzPlibPB7jjsbi','2iNaUrp1SRBFoJnJqhbwS8','3SdaSSuc4prTO9IKFZEvxd','21ObFu22NhjfhXJm51Idij','2jKNbuegISV7YPdvXu3vaB','7r5rLLUes9m2bKvdmESzBP','6JPcT2uMbQzmdp6VJFa9bA']

我确定解决方案很简单-但是我花了数小时试图弄清楚这一点。

如何获取从sp.albums生成的.json文件中收集的多个专辑的所有曲目？

非常感谢您抽出宝贵的时间阅读本文，感谢您的投入！

解决方法

如果我正确地理解了您的代码和数据，则您不是从一张专辑中获得全部歌曲，而是从第一张专辑中获得第一首歌曲，从第二张专辑中获得第二首歌曲，依此类推（请检查一下）。我认为您必须将代码更改为此：

track_ids = []
for album_id in range(len(fugazi_songs['albums'])):
    for track_id in range(len(fugazi_songs['albums'][album_id]['tracks']['items']))
        track_ids.append(fugazi_songs['albums'][album_id]['tracks']['items'][track_id]['id'])
