我正在向SPotify API内部发出请求for loop，如下所示：

track_ids = []
#get track_ids
for track in random.sample(pitchfork_tracks, 10):
    results = sp.search(q=track, type='track') #here I call Spotify endpoint
    items = results['tracks']['items']
    for t in items:
        track_ids.append(t['uri'])
return track_ids

我可以，但如果我尝试，控制台不会返回任何内容print。treturn track_ids

日志告诉我：

似乎一遍又一遍地开始和结束连接与它有关......或者我在这里遗漏了一些明显的东西？

我该如何解决这个问题并设法建立我的track_ids list？

track_ids范围在您的功能内。要打印列表，您可以这样做

track_ids = yourfunction()
print track_ids

或者

您可以将track_ids列表设为全局并在您的函数之外声明它。
