title: json.loads and Redis in python 3.5
body: <p>I created a JSON object with json.dumps() and RPUSH(ed) it in a redis list.
  When getting back the JSON with LRANGE ( redis.lrange() ) I receive a binary string</p>
  
  <pre><code> b'{"si":"00:ff" ...
  </code></pre>
  
  <p>So json.loads() raises an error:
  *** TypeError: the JSON object must be str, not 'bytes'
  How should I revert to ascii ?</p>
