刚开始使用 Spotipy 和 Python3，我想使用 new_releases() 打印艺术家姓名和艺术家专辑

如何解决刚开始使用 Spotipy 和 Python3，我想使用 new_releases() 打印艺术家姓名和艺术家专辑

到目前为止，我可以使用它打印出我选择的人的所有专辑

spotify = spotipy.Spotify(client_credentials_manager=SpotifyClientCredentials(client_id,client_secret))
results = spotify.artist_albums(posty_uri,album_type='album')
albums = results['items']
while results['next']:
    results = spotify.next(results)
    albums.extend(results['items'])
    
for album in albums:        
        print(album['name'])

我试图通过这样做对 new_releases() 执行类似的过程

newReleases = spotify.new_releases()
test = newReleases['items']

但这会在 test = newReleases['items'] 行上引发我的错误。如果有人熟悉 Spotipy 并且知道如何从 new_releases() 返回诸如发行日期、艺术家姓名、专辑名称之类的信息，我将不胜感激。

解决方法

我有点困惑，因为 the documentation 说 new_releases 方法返回一个列表。无论如何，它是一个包含列表的单项字典。

但是，该列表包含的词典看起来有点笨拙，所以我理解您为什么要问这个问题。

您可以利用 collections.namedtuple 数据结构更轻松地查看相关信息。我不认为这是转换这些数据的最佳方式，但在我看来这是一种不错的方式。

import collecdtions as co 

# namedtuple data structure that will be easier to understand and use 
Album = co.namedtuple(typename='Album',field_names=['album_name','artist_name','release_date'])
newReleases2 = [] # couldn't think of a better name

for album in newReleases['albums']['items']: 
    artist_sublist = [] 
    for artist in album['artists']: 
        artist_sublist.append(artist['name'])
    newReleases2.append(Album(album_name=album['name'],artist_name=artist_sublist,release_date=album['release_date'])) 

这会产生以下命名元组列表：

[Album(album_name='Only Wanna Be With You (Pokémon 25 Version)',artist_name=['Post Malone'],release_date='2021-02-25'),Album(album_name='AP (Music from the film Boogie)',artist_name=['Pop Smoke'],release_date='2021-02-26'),Album(album_name='Like This',artist_name=['2KBABY','Marshmello'],Album(album_name='Go Big (From The Amazon Original Motion Picture Soundtrack Coming 2 America)',artist_name=['YG','Big Sean'],Album(album_name='Here Comes The Shock',artist_name=['Green Day'],release_date='2021-02-21'),Album(album_name='Spaceman',artist_name=['Nick Jonas'],Album(album_name='Life Support',artist_name=['Madison Beer'],Album(album_name="Drunk (And I Don't Wanna Go Home)",artist_name=['Elle King','Miranda Lambert'],Album(album_name='PROBLEMA',artist_name=['Daddy Yankee'],Album(album_name='Leave A Little Love',artist_name=['Alesso','Armin van Buuren'],Album(album_name='Rotate',artist_name=['Becky G','Burna Boy'],release_date='2021-02-22'),Album(album_name='BED',artist_name=['Joel Corry','RAYE','David Guetta'],Album(album_name='A N N I V E R S A R Y (Deluxe)',artist_name=['Bryson Tiller'],Album(album_name='Little Oblivions',artist_name=['Julien Baker'],Album(album_name='Money Long (feat. 42 Dugg)',artist_name=['DDG','OG Parker'],Album(album_name='El Madrileño',artist_name=['C. Tangana'],Album(album_name='Skegee',artist_name=['JID'],release_date='2021-02-23'),Album(album_name='Coyote Cry',artist_name=['Ian Munsick'],Album(album_name='Rainforest',artist_name=['Noname'],Album(album_name='The American Negro',artist_name=['Adrian Younge'],release_date='2021-02-26')]

如果您想在此列表中查看与第 11 张专辑相关的艺术家，您可以这样做：

In [62]: newReleases2[10].artist_name                                                               
Out[62]: ['Becky G','Burna Boy']

编辑：在对此答案的评论中，OP 也要求获得专辑封面。

请参阅辅助函数，并稍微修改以下代码：

import os
import requests

def download_album_cover(url):
    # helper function to download album cover 
    # using code from: https://stackoverflow.com/a/13137873/42346
    download_path = os.getcwd() + os.sep + url.rsplit('/',1)[-1] 
    r = requests.get(url,stream=True) 
    if r.status_code == 200: 
        with open(download_path,'wb') as f: 
            for chunk in r.iter_content(1024): 
                f.write(chunk) 
        return download_path 

# modified data structure
Album = co.namedtuple(typename='Album','album_cover','release_date'])

# modified retrieval code
newReleases2 = []                                                                          

for album in newReleases['albums']['items']: 
    album_cover = download_album_cover(album['images'][0]['url']) 
    artist_sublist = []  
    for artist in album['artists']:  
        artist_sublist.append(artist['name']) 
    newReleases2.append(Album(album_name=album['name'],album_cover=album_cover,release_date=album['release_date'])) 

结果：
