title: Iterate over a list of floats
body: <p>I have a list of floating point numbers that I need to iterate over and find the lowest out of the last 4 numbers</p>
  
  <pre><code>list = [1.1344, 1.254, 1.654, 1.2335, 1.43545]`
  
  for i in list [-4]:
  
      print i
  </code></pre>
  
  <p>but I keep getting: </p>
  
  <pre><code>TypeError: 'float' object is not iterable
  </code></pre>
