title: How to create a 2d list with all same values but can alter multiple elements within? (python)
body: <p>I'm trying to create a list that holds this exact format: <code>[[2],[2],[2],[2],[2],[2],[2],[2],[2],[2]]</code></p>
  
  <p>and when <code>list[3][0] = 9</code> is called, the list becomes <code>[[2],[9],[2],[9],[2],[9],[2],[9],[2],[9]]</code></p>
  
  <p>How do I create the list in the first place that will allow me to change these many elements with only one line?</p>
