You don’t need to post/delete and specifically reply to me when theres only us two here anyway. 
You put the headers back to front.
You did {value: key} instead of {key: value}
As per the example I linked
Then it should be
response = requests.get('https://api.twitch.tv/helix/streams?game_id=33214', headers={'Client-ID': yourClientID, 'Authorization': 'Bearer AccessToken'})
Please note: I’m not a python native so this could be incorrect
