title: Creating a concatenated list via list comprehension
body: <p>I'm working with the following code where <code>pages</code> refers to a list of strings and <code>get_film_links</code> is a function which returns a list:</p>
  <pre><code>link_list = []
  for page in pages:
      link_list += get_film_links(page)
  </code></pre>
  <p>When the above loop is complete, <code>link_lists</code> will return as a single list. I've been trying to create the same code by using a list comprehension. Using the following code, I end up creating a list of lists, rather than a single concatenated list as the original code does.</p>
  <pre><code>link_list = [get_film_links(page) for page in pages]
  </code></pre>
  <p>How can I adjust this list comprehension to create a single, concatenated list rather than a list of lists?</p>
