title: How to append or concatenate 'n' numpy arrays?
body: <p>I want to append 10 numpy arrays one after another. Is there any functions like</p>
  
  <pre><code>vm_all = np.concatenate(vm_1,vm_2,vm_3,vm_4,vm_5,vm_6,vm_7,vm_8,vm_9,vm_10)
  </code></pre>
  
  <p>or</p>
  
  <pre><code>cre_all = np.append(cre_1,cre_2,cre_3,cre_5,cre_6,cre_7,cre_8,cre_9,cre_10)
  </code></pre>
  
  <p>The problem with <code>append()</code> is that it takes at most 3 arguments. And <code>concatenate()</code> takes at most 2 arguments.</p>
  
  <p>We can archive the target with <code>for</code> loop. But I would like to know whether any function  available for this. </p>
