title: Adding an array to the end of another Python
body: <p>I'm very new to python and I have been faced with the task of taking several arrays into another array, this is inside of a loop.
  So if you had</p>
  
  <pre><code>a = np.array([2,3,4,3,4,4,5,3,2,3,4])
  </code></pre>
  
  <p>and</p>
  
  <pre><code>b = np.array([1,1,1,1,1,2,23,2,3,3,3])
  </code></pre>
  
  <p>and </p>
  
  <pre><code>c = np.array([])
  </code></pre>
  
  <p>and wanted the result</p>
  
  <pre><code>c = [[2,3,4,3,4,4,5,3,2,3,4],
       [1,1,1,1,1,2,23,2,3,3,3]]
  </code></pre>
  
  <p>so if I did <code>c[0,:]</code> I would get <code>[2,3,4,3,4,4,5,3,2,3,4]</code>
  I tried using <code>c = [c, np.array(a)]</code> then next iteration you get <code>c = [c, np.array(b)]</code>
  but I i do <code>c[0,:]</code> i get the error message <code>list indices must be integers not tuples</code></p>
  
  <p>EDIT:</p>
  
  <p>When I get it to print out <code>c</code> it gives <code>[array([2,3,4,3,4,4,5,3,2,3,4],dtype = unit8)]</code></p>
  
  <p>Do you have any ideas?</p>
