title: Recursion assignment
body: <pre><code>def swap(aList):
  
    if len(aList) == 0:
        return 0
    elif len(aList) == 1:
        print(aList[0])
        return aList[0]
    return aList[0] + swap(aList[2:])
  
  aList = [["abcdefgh"]]
  
  swap(aList)
  </code></pre>
  
  <p>The code above prints, but it prints the aList in order, from a-h. 
  LIKE SO:
  "abcdefgh"</p>
  
  <p>I need to print every two letters in reverse; LIKE SO:
  "badcfehg"</p>
