title: Extracting Columns from numpy array
body: <p>Assuming I have a numpy array </p>
  
  <pre><code>A = np.array([[1,2,3,4],[5,6,7,8]])
  </code></pre>
  
  <p>and I want to access it row wise I can do </p>
  
  <pre><code>for row in A:
    print(row)
  </code></pre>
  
  <p>which results in me having </p>
  
  <pre><code>[1 2 3 4]
  [5 6 7 8]
  </code></pre>
  
  <p>Is there a similar column wise method to access the array 
  which will result in me having</p>
  
  <pre><code>[1 5]
  [2 6]
  [3 7]
  [4 8]
  </code></pre>
  
  <p>I know I can use indices but, I just want to know if there is a way to access the array column wise without indices. </p>
  
  <p>Thanks </p>
