body: <p>After a MySQL select statement, I am left with the following:</p>
  
  <pre><code>set([('1@a.com',), ('2@b.net',), ('3@c.com',), ('4@d.com',), ('5@e.com',), ('6@f.net',), ('7@h.net',), ('8@g.com',)])
  </code></pre>
  
  <p>What I would like to have is a </p>
  
  <pre><code>emaillist = "\n".join(queryresult)
  </code></pre>
  
  <p>to in the end, have a string:</p>
  
  <pre><code>1@a.com
  2@b.net
  3@c.com
  etc
  </code></pre>
  
  <p>What would be the proper way to convert this nested tuple into string?</p>
