title: How to convert words inputs to a list
body: <p>I need this for my homework. I'm trying to create a a program where I ask the user for some words. I want those words to be on a list so then I can use <code>.index</code> to call some.</p>
  
  <p>I tried to use <code>.set</code> or <code>sorted(set())</code>. It worked with numbers but not words.   For instance:</p>
  
  <pre><code>x = list (raw_input ("insert numbers"))
  set = set(x)
  result = list(set)
  result.sort()
  print result
  </code></pre>
  
  <p>From this, I get some good results.  If I feed it numbers, I get the output I expect:</p>
  
  <pre><code>insert numbers 817654
  [' ', '1', '4', '5', '6', '7', '8']
  </code></pre>
  
  <p>If I enter words, it sorts the letters:</p>
  
  <pre><code>insert numbers now i will a rhyme construct ...
  [' ', '.', 'a', 'c', 'e', 'h', 'i', 'l', 'm', 'n', 'o', 'r', 's', 't', 'u', 'w', 'y']
  </code></pre>
  
  <p>The output I <em>want</em> is </p>
  
  <pre><code>['a', 'construct', 'i', 'now', 'rhyme', 'will']
  </code></pre>
