title: Append inner 0 & 1st index to all elements in 2nd index two-dimensional List of Lists - python
body: <p>Hello new to python here... wondering what the best way is to solve a problem like this. </p>
  
  <p>I have a 2d array that look something like this:</p>
  
  <pre><code>a = [['October 17', 'Manhattan', '10024, 10025, 10026'], 
       ['October 17', 'Queen', '11360, 11362, 11365, 11368']]
  </code></pre>
  
  <p>Would like to iterate over this to create a new list or data frame that looks like the following:</p>
  
  <pre><code>10024, October 17, Manhattan
  10025, October 17, Manhattan
  10026, October 17, Manhattan
  11360, October 17, Queens
  11362, October 17, Queens
  11365, October 17, Queens
  11368, October 17, Queens
  </code></pre>
  
  <p>Any insight would be greatly appreciated. </p>
  
  <p>Thank you.  </p>
