title: Removing subarray from array
body: <p>I have a numpy array A and B. </p>
  
  <pre><code>A = [ 1, 2, 5, 9.8, 55, 3]
  B = [ 3, 4] 
  </code></pre>
  
  <p>Now, how to remove A[3] &amp;  A[4]  that is whatever indices array B is having and then put them at the start of array A. 
  So,  I want my output to be </p>
  
  <pre><code>A = [9.8, 55, 1, 2, 5,  3]
  </code></pre>
  
  <p>Note : Both A and B are numpy arrays. </p>
  
  <p>Any help is highly appreciated. </p>
