title: How to add a list as an element of a numpy n-D Matrix
body: <p>I have been having lots for issues trying to find a way to put a list inside a numpy n-D Matrix. What I want is to have a numpy n-D matrix and all the elements inside that matrix should be lists. so that I can add/ append numbers into those lists.</p>
  
  <pre><code> A = [X1,X2,X3]
       [Y1,Y2,Y3]
       [Z1,Z2,Z3]
  </code></pre>
  
  <p>ALL THE Xs,Ys AND Zs ARE LISTS.
  Thanks in advance</p>
