title: How to insert the contents of one list into another
body: <p>I am trying to combine the contents of two lists, in order to later perform processing on the entire data set.  I initially looked at the built in <code>insert</code> function, but it inserts as a list, rather than the contents of the list.  </p>
  
  <p>I can slice and append the lists, but is there a cleaner / more Pythonic way of doing what I want than this: </p>
  
  <pre><code>array    = ['the', 'fox', 'jumps', 'over', 'the', 'lazy', 'dog']
  addition = ['quick', 'brown']
  
  array = array[:1] + addition + array[1:]
  </code></pre>
