Почему я получаю только одну песню из плейлистов Spotify вместо всех?

/ 09 июня 2019

Я новичок в программировании.Я хочу сделать анализ настроений в сочетании с анализом аудиофункций моих плейлистов Spotify с использованием SpotiPy и PyLyrics.

Я пытаюсь заставить этот код работать, но мне удалось получить только одну песню для моего CSV, хотя мойплейлисты намного больше. 

from spotipy.oauth2 import SpotifyClientCredentials
import spotipy
import json
import csv
import pylyrics3
from nltk.sentiment.vader import SentimentIntensityAnalyzer as SIA

client_credentials_manager = SpotifyClientCredentials(client_id='#########', client_secret='#########')

sp = spotipy.Spotify(client_credentials_manager=client_credentials_manager)

sentiment_analyzer = SIA()

def get_features(track_id):
    features_results = sp.audio_features(track_id)
    json_features = json.dumps(features_results)
    features_data = json.loads(json_features)
    features_list = list(features_data[0].values())
    return features_list

playlist_ids = [
    "6itzpx6OEo76NWSpy0f3fc",
    "3itylhqRqKPS4nOgWmU7lU",
    "63UBtWxXAtUIR6djuNhGj9",
    "6tZo11hLgEslYdMP5wu4q8",
    "3XXl0JH2uLXpmO5EbH6XPb"
]

# Audio features
feature_names = [
  "danceability",
  "energy",
  "key",
  "loudness",
  "mode",
  "speechiness",
  "acousticness",
  "instrumentalness",
  "liveness",
  "valence",
  "tempo",
  "type",
  "id",
  "uri",
  "track_href",
  "analysis_url",
  "duration_ms",
  "time_signature"
]

username = '#########'

# Write data to CSV file
data_file = open('data.csv','w')

writer = csv.writer(data_file)

# Write header
writer.writerow(['track_id', 'playlist_id', 'date_added', 'track_name', 'first_artist'] + feature_names + ['lyrics', 'neg', 'neu', 'pos', 'compound'])

for playlist_id in playlist_ids:
    print('Querying playlist: ' + str(playlist_id))

    repeat_query = True
    offset_n = 0
    for i in range(2):
        # Query Spotify API
        if i > 0:
            print('Repeating query')
            offset_n += 50
        results = sp.user_playlist_tracks(username, playlist_id, offset=offset_n)
        json_results = json.dumps(results)
        data = json.loads(json_results)

# Write rows

for track in data['items']:
                track_id = track['track']['id']
                date_added = track['added_at']
                track_name = track['track']['name']
                first_artist = track['track']['artists'][0]['name']

# Track features

features = get_features(track_id)

# Try to get lyrics, if available

lyrics = ''

try:
                lyrics = pylyrics3.get_song_lyrics(first_artist, track_name)

except:
                pass

# Sentiment Analysis

neg = None            
neu = None            
pos = None

compound = None

if lyrics:
                snt = sentiment_analyzer.polarity_scores(lyrics)
                neg = snt['neg']
                neu = snt['neu']
                pos = snt['pos']
                compound = snt['compound']

writer.writerow([track_id, playlist_id, date_added, track_name, first_artist] + features + [lyrics] + [neg, neu, pos, compound])

#if data['total'] < 50:
#           break           ????

print('Done querying')

data_file.close()

Кто-нибудь знает, что здесь не так и как получить все треки из моих плейлистов в csv?
