使用Python从SoundCloud中提取URL

Question

我的目标是使用python2.7.9从soundcloud的特定艺术家（例如lil wayne）的soundcloud url中提取曲目和播放列表。我尝试了从https://github.com/soundcloud/soundcloud-python获取的以下代码

import soundcloud

client = soundcloud.Client(client_id='xxx')

tracks = client.get('/tracks', limit=10)
for track in tracks:
    print track.title    
app = client.get('/tracks/30709985')
print app.permalink_url

我尝试过改变tracks = client.get('lilwayne/tracks', limit=10)和改变app = client.get('/lilwayne/tracks')，但是我得到了以下的回溯：

Traceback (most recent call last):
  File "/Users/er/Desktop/Soundcloud.py", line 7, in <module>
    tracks = client.get('lilwayne/tracks', limit=10)
  File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/soundcloud/client.py", line 133, in _request
    return wrapped_resource(make_request(method, url, kwargs))
  File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/soundcloud/request.py", line 148, in make_request
    result.raise_for_status()
  File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/requests/models.py", line 844, in raise_for_status
    raise HTTPError(http_error_msg, response=self)
HTTPError: 404 Client Error: Not Found for url: https://api.soundcloud.com/lilwayne/tracks?limit=10&client_id=XXX

问：为了在soundcloud上提取特定艺术家的曲目，我是否更改client.get()的内容或任何建议？你知道吗
