title: How to print out floats in list
body: <p>So I was trying to print out float numbers in a list in reverse but the output keep saying none. Why is that?</p>
  <pre class="lang-py prettyprint-override"><code>nums = [1.4, 1.2054, 2.2, 2.5, 3.66, 3.0, 4.024, 4.00001, 5.5, 5.1]
  
  for i in nums:
      print(nums.reverse())
  </code></pre>
  <p>Output:</p>
  <pre><code>None
  None
  None
  None
  None
  None
  None
  None
  None
  </code></pre>
