title: Iterating through vtkFloatArray
body: <p>I noticed that the return type of a function I'm calling is <code>vtkFloatArray</code>. I want to check the components of this array, but, not sure how to iterate through its components.</p>
  
  <p>Since when I tried to iterate through the elements, I got the following error:</p>
  
  <pre><code>TypeError: 'vtkobject' object is not iterable
  </code></pre>
  
  <p>Why am I getting such error?</p>
  
  <p>Thanks.</p>
