Python- How to check if a Twitch stream is online

I'm trying to check whether a twitch stream is online using python. This question has been asked here before however now I think the responses are out of date in relation to the twitch API. For example http://ift.tt/2wxrjri just says that I did not specify a user ID. {"error":"Bad Request","status":400,"message":"No client id specified"}

Thanks for any help!
