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答案

【问题标题】：New to using Spotipy and Python3, I want to use new_releases() to print Artist name and the artist album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
【发布时间】：2021-03-05 02:54:37
【问题描述】：

到目前为止，我可以使用我选择的人打印出所有专辑

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'])

我试图通过这样做来为 new_releases() 做一个类似的过程

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

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

【解决方案1】：

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，该列表包含的字典似乎有点笨拙，所以我理解您为什么要问这个问题。

您可以利用collections.namedtuple 数据结构更容易查看相关信息。我并没有声称这是转换这些数据的最佳方法，但在我看来这是一种不错的方法。

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'], release_date='2021-02-26'),
 Album(album_name='Go Big (From The Amazon Original Motion Picture Soundtrack Coming 2 America)', artist_name=['YG', 'Big Sean'], release_date='2021-02-26'),
 Album(album_name='Here Comes The Shock', artist_name=['Green Day'], release_date='2021-02-21'),
 Album(album_name='Spaceman', artist_name=['Nick Jonas'], release_date='2021-02-25'),
 Album(album_name='Life Support', artist_name=['Madison Beer'], release_date='2021-02-26'),
 Album(album_name="Drunk (And I Don't Wanna Go Home)", artist_name=['Elle King', 'Miranda Lambert'], release_date='2021-02-26'),
 Album(album_name='PROBLEMA', artist_name=['Daddy Yankee'], release_date='2021-02-26'),
 Album(album_name='Leave A Little Love', artist_name=['Alesso', 'Armin van Buuren'], release_date='2021-02-26'),
 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'], release_date='2021-02-26'),
 Album(album_name='A N N I V E R S A R Y (Deluxe)', artist_name=['Bryson Tiller'], release_date='2021-02-26'),
 Album(album_name='Little Oblivions', artist_name=['Julien Baker'], release_date='2021-02-26'),
 Album(album_name='Money Long (feat. 42 Dugg)', artist_name=['DDG', 'OG Parker'], release_date='2021-02-26'),
 Album(album_name='El Madrileño', artist_name=['C. Tangana'], release_date='2021-02-26'),
 Album(album_name='Skegee', artist_name=['JID'], release_date='2021-02-23'),
 Album(album_name='Coyote Cry', artist_name=['Ian Munsick'], release_date='2021-02-26'),
 Album(album_name='Rainforest', artist_name=['Noname'], release_date='2021-02-26'),
 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 也要求获取专辑封面。

请查看辅助函数，并在下面稍微修改代码：

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',field_names=['album_name',
                                                    'album_cover',
                                                    'artist_name',
                                                    '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, 
                              artist_name=artist_sublist, 
                              release_date=album['release_date']))

结果：

【讨论】：

非常感谢！最好的方法与否我现在可以完美地工作！我想做的最后一件事是尝试为每个新版本获取专辑封面。有什么想法吗？
@Rogicar：干杯！对于专辑封面，我使用requests 模块合并了一些快速图片下载代码。请查看编辑后的答案。
