title: Python: multi-dimensional lists - appending one 2D list into another list
body: <p>I'm looking to create a master array/list that takes several two dimensional lists and integrates them into the larger list.</p>
  
  <p>For example I have a <code>TableA[]</code> which has <code>dates</code> as one array/list and <code>prices</code> as another array/list. I have another as TableB[] which has the same. TableA[0][0] has the first date; TableA[0][1] has the first price; TableA[1][0] has the second date, and so on.</p>
  
  <p>I would like to create <code>BigTabe[]</code> that has <code>BigTable[0][0][0] = TableA[0][0]</code> and <code>BigTable[1][0][0] = TableB[0][0]</code>.</p>
  
  <p>Any guidance would be much appreciated. Thank you!</p>
