title: How to move from end of list, to start in Python's lists?
body: <p>How to get the first value of a list, from its last two values.</p>
  
  <p>For example I have a list:</p>
  
  <pre><code>list1 = ['a','b','c','d','y','z']
  # I know that going from 'a' to 'y' is using negatives,
  n = 0 - 2 
  list1[n]
  # This will give the value of 'y'
  
  # but how do I do the opposite? 'y' to 'a' ?
  # not fetching the values from 'y' to 'a', instead, traversing from 'y' to 'a'
  </code></pre>
