title: Python - List comprehension with tuple unpack
body: <p>I have a list of tuples like:
      <code>tuple_list = [ (0,1,2), (3,4,5), (6,7,8) ]</code></p>
  
  <p>I need to create a list where each tuple is converted into a list with other static items added e.g.:</p>
  
  <pre><code>new_list = [ [var1, var2, unpack(t)] for t in tuple_list ]
  </code></pre>
  
  <p>How would I accomplish this in python?</p>
