title: Remove brackets from numpy array
body: <p>I have an array whose string representation which prints like this </p>
  
  <pre><code>['w_49c9417' 'w_b6ae946' 'w_1596a47' 'w_b68d04']
  </code></pre>
  
  <p>This a numpy array, is there any way i can remove those brackets, I tried <code>'.'join(thearray)</code> but I get:</p>
  
  <pre><code>Type Error: sequence item 0: expected instance, Numpy.ndarray found
  </code></pre>
  
  <p>What i would ideally like this to be string representation to print like:  </p>
  
  <pre><code>'w_49c9417' 'w_b6ae946' 'w_1596a47' 'w_b68d04'
  </code></pre>
  
  <p>Any suggestions would be helpful!
  Thanks in advance.</p>
