title: python: add str and str.title() to list using list comprehension
body: <p>I am reading in a file with words, like this:</p>
  
  <pre><code>stop_words = [x for x in open('stopwords.txt', 'r').read().split('\n')]
  </code></pre>
  
  <p>but I also need the title() version of the word in the same list. Can I do this using one list comprehension?</p>
