title: Python SQLAlchemy response type to string
body: <p>When I run a SQLAlchemy query to get values from a SQLAlchemy.String() column;</p>
  <pre class="lang-py prettyprint-override"><code>query = db.session.query(self.hosts_class.cluster.distinct())
  
      for row in query.all()
  </code></pre>
  <p>Iterating and printing the result object results in output like;
  <code>('sometext',)</code></p>
  <p>If I browse the row object I can see that row contains a key, value pair of &quot;0&quot;: &quot;sometext&quot;.  What's the correct way to access this value from row?</p>
