title: Finding the index value of the smallest number in a list?
body: <p>Say I have a list of numbers <code>[ 20, 15, 27, 30 ]</code>  </p>
  
  <p>How would I return the index number of the smallest value in this list. (<code>15</code>) Obviously, min(lst) will return the smallest number itself, but how do I instead return it's index "<code>1</code>" ?</p>
