HTTP Error 429: Unknown Status Code

Trying to retrieve metadata (in particular, the license) for multiple sounds on FreeSound, using the Python API with python 3.

Working example:

import freesound
client = freesound.FreesoundClient()
client.set_token(MYTOKEN, "token")
sound = client.get_sound(100852)

Error:

Note: the code worked fine earlier for this file, but now it crashes. Maybe I'm being throttled and the response message breaks the API?

That's definitely because of throttling. We should make the python client handle that in a better way. In the meanwhile you can try/except HTTPError. Thanks for reporting @justinsalamon!
