title: Converting the output of itertools.permutations from list of tuples to list of strings
body: <p>Having some issues with a list after using the itertools permutations function.</p>
  
  <pre><code>from itertools import permutations
  
  def longestWord(letters):
      combinations = list(permutations(letters))
      for s in combinations:
          ''.join(s)
      print(combinations)
  
  longestWord("aah")  
  </code></pre>
  
  <p>The output looks like this:</p>
  
  <pre><code>[('a', 'a', 'h'), ('a', 'h', 'a'), ('a', 'a', 'h'), ('a', 'h', 'a'), 
   ('h', 'a', 'a'), ('h', 'a', 'a')]
  </code></pre>
  
  <p>I would like this to be a simple list, but it seems to be coming out as a list of tuples(?). Can anyone help me format this so it comes out as the following:</p>
  
  <pre><code>['aah', 'aha', 'aah', 'aha', 'haa', 'haa']
  </code></pre>
