如何找出播放列表在Spotipy中是否有播放列表图片封面？

import spotipy
from spotipy.oauth2 import SpotifyClientCredentials

# 设置Spotify API的客户端ID和客户端密钥
client_id = 'YOUR_CLIENT_ID'
client_secret = 'YOUR_CLIENT_SECRET'

# 创建Spotify客户端对象
client_credentials_manager = SpotifyClientCredentials(client_id=client_id, client_secret=client_secret)
sp = spotipy.Spotify(client_credentials_manager=client_credentials_manager)

# 获取用户的播放列表信息
username = 'YOUR_USERNAME'
playlists = sp.user_playlists(username)

# 遍历每个播放列表
for playlist in playlists['items']:
    # 检查播放列表是否有图片封面
    if len(playlist['images']) > 0:
        print("播放列表 '{}' 有图片封面。".format(playlist['name']))
        print("封面图片URL: {}".format(playlist['images'][0]['url']))
    else:
        print("播放列表 '{}' 没有图片封面。".format(playlist['name']))
