title: Python assign value to multiple list elements
body: <p>I am starting maintenance on some code that assigns values to variables in this manner:</p>
  
  <pre class="lang-py prettyprint-override"><code>[thing_filenames, thing_list]=Load_Things(bunch_of_things)
  </code></pre>
  
  <p>I haven't seen values assigned to variables with brackets on the left side. Can someone please provide a pointer for where I can start to understand this statement?</p>
