title: Splitting a Matrix in Python
body: <p>I want to split any matrix (most likely will be a 3x4) into two. One part will be the left hand and then the right hand - only the last column. </p>
  
  <pre><code>[[1,0,0,4],              [[1,0,0],       [4,
   [1,0,0,2],     ---&gt; A=   [1,0,0],   B =  2,
   [4,3,1,6]]               [4,3,1]]        6]
  </code></pre>
  
  <p>Is there a way to do this in python and assign then as A and B? </p>
  
  <p>Thank you!</p>
