title: Python - Compare two lists in a comprehension
body: <p>I'm trying to understand how comprehensions work.</p>
  
  <p>I would like to loop through two lists, and compare each to find differences.
  If one/or-more word(s) is different, I would like to print this word(s).</p>
  
  <p><strong>I'd like this all in one nice line of code,  which is why I'm interested in comprehensions.</strong></p>
