title: Python change UUID object to string representation list
body: <p>When retrieving a queryset with <code>values_list</code> of PKs there are of type <code>UUIDField</code> Django gives you a list of UUIDField objects and NOT a list of string UUIDs.</p>
  
  <p>For example, the following gives me a query set:</p>
  
  <pre><code>items = Item.objects.values_list('id', flat=True).filter()
  </code></pre>
  
  <p>Where the output of <code>print(items)</code> is:</p>
  
  <pre><code>[UUID('00c8aa9e-2f61-4bac-320c-ab26b8fb1de9')]
  </code></pre>
  
  <p>But I would like the list to be a string representation of of UUID's i.e.</p>
  
  <pre><code> ['00c8aa9e-2f61-4bac-320c-ab26b8fb1de9']
  </code></pre>
  
  <p>I can do this with each object individual in a loop but I want to change the whole queryset. Is this possible?</p>
  
  <p>I have tried:</p>
  
  <pre><code>print(str(items))
  </code></pre>
