title: Turn NumPy Array of characters into a string
body: <p>I have a numpy array of characters and when I write it to file it writes as:</p>
  
  <pre><code>['K' 'R' 'K' 'P' 'T' 'T' 'K' 'T' 'K' 'R' 'G' 'L']
  </code></pre>
  
  <p>I want it to write with just the letters and without the brackets or quotations i.e. as:</p>
  
  <pre><code>KRKPTTKTKRGL 
  </code></pre>
  
  <p>I have looked at numpy documentation and from what I have gathered the solution is a chararray however it looks like this is not as functional as a normal array.</p>
  
  <p>Any help would be great. Thanks!</p>
