Snippet para fazer o ranking de contribuidores da nossa playlist

spoti.py

from collections import defaultdict

import spotipy
from spotipy.oauth2 import SpotifyClientCredentials

sp = spotipy.Spotify(auth_manager=SpotifyClientCredentials())

offset, limit = 0, 100
playlist_id = '6tPcPBeTEoPqaZcR03IzwN'
ranking = defaultdict(int)

while True:
    results = sp.playlist_items(playlist_id, offset=offset, limit=limit)
    if not len(results['items']):
        break
    offset += limit
    for item in results['items']:
        user_id = item['added_by']['id']
        ranking[user_id] += 1

total = sum(ranking.values())
sorted_ranking = dict(
    reversed(sorted(ranking.items(), key=lambda item: item[1])))
for user, cnt in sorted_ranking.items():
    info = sp.user(user)
    print("%5d (%5.2f %%)\t%-30s" %
          (cnt, (100 * cnt / total), info['display_name']))

Só lembra de definir as variáveis SPOTIPY_CLIENT_ID e SPOTIPY_CLIENT_SECRET
