title: How to create a list of empty lists
body: <p>Apologies if this has been answered before, but I couldn't find a similar question on here.</p>
  
  <p>I am pretty new to Python and what I am trying to create is as follows:</p>
  
  <pre><code>list1 = []
  list2 = []
  results = [list1, list2]
  </code></pre>
  
  <p>This code works absolutely fine, but I was wondering if there was a quicker way to do this in one line. </p>
  
  <p>I tried the following, which didn't work, but I hope it demonstrates the sort of thing that I'm after:</p>
  
  <pre><code>result = [list1[], list2[]]
  </code></pre>
  
  <p>Also, in terms of complexity, would having it on one line really make any difference? Or would it be three assignments in either case?</p>
