使用 Spotipy 从 Python 中的打印中获取特定行
Getting specific lines from a print in Python with Spotipy
我正在使用 Python 和 Spotipy 编写一些代码,我对编码还比较陌生。我有一些代码可以获取有关 Spotify 播放列表的所有信息并为我打印出来:
from spotipy.oauth2 import SpotifyClientCredentials
import spotipy
import json
client_credentials_manager = SpotifyClientCredentials()
sp = spotipy.Spotify(client_credentials_manager=client_credentials_manager)
playlist_id = 'spotify:playlist:76CVeJDw2b90up5PgkZXyU'
results = sp.playlist(playlist_id)
#print(json.dumps(results, indent=4))
print((json.dumps(results, indent=4)))
它运行良好并为我提供了所有信息。我的问题是我只需要印刷品中的细节:

不知何故,我需要从这个长打印中提取艺术家和歌曲名称,最好将其放入变量中。如果播放列表中有多首歌曲,也不确定这将如何工作。
如果我只打印艺术家和歌名而不打印所有信息,这也是一种解决方案。
sp.playlist
returns 一个字典,所以你可以通过它们的键简单地访问它的值。例如:
>>> results['name']
'TEST'
JSON 是一种数据序列化格式,即一种将对象表示为纯文本并将其从文本解析回来的标准化方式。 json.dumps
因此将字典对象转换为文本字符串。例如,如果您想将结果保存到文件并稍后将其加载回来,这将很有用。您不需要它来访问 results
.
中的内容
(虽然这是一个播放列表——您需要获取每个 song/track 的信息才能获得其艺术家和名称。)
根据您发布的示例,您似乎只有 1 首名为 "Africa" 的歌曲,作者是艺术家 "TOTO"。复制曲目以包含两首歌曲,我添加了另一首曲目,其中包含两位艺术家以测试数组。
如果 json 被加载到一个名为 results
的变量中,那么(正如@xcmkz 所说)你有一个 python 字典并可以进行相应的处理。
尝试使用以下命令横穿您的字典,将艺术家和歌曲附加到列表中:
song_dict = {}
for track in results['tracks']['items']:
song_name = track["track"]["name"]
a2 = []
for t1 in track['track']['artists']:
a2.append(t1['name'])
song_dict.update({song_name: a2})
print(f'Dictionary of Songs and Artists:')
for k, v in song_dict.items():
print(f'Song --> {k}, by --> {", ".join(v)}')
结果:
Dictionary of Songs and Artists:
Song --> Africa, by --> TOTO
Song --> Just Another Silly Song, by --> Artist 2, Artist 3
