title: Python: Munging data with '.join' (TypeError: sequence item 0: expected string, tuple found)
body: <p>I have data in following format:</p>
  
  <pre><code>[('A', 'B', 'C'),
   ('B', 'C', 'A'),
   ('C', 'B', 'B')]
  </code></pre>
  
  <p>I'm looking to get this:</p>
  
  <pre><code>ABC
  BCA
  CBB
  </code></pre>
  
  <p>I'm able to convert one tuple at the time:</p>
  
  <pre><code>&gt;&gt; "".join(data[0])
  .. 'ABC'
  </code></pre>
  
  <p>However when I'm trying to conver the whole list Python gives me an error:</p>
  
  <pre><code>&gt;&gt; "".join(data[:])
  .. TypeError: sequence item 0: expected string, tuple found
  </code></pre>
  
  <p>Any advice how I'll be able to convert the whole list?</p>
  
  <p>Thank you!</p>
