title: Two-dimensional list in Python?
body: <p>So I have this code:</p>
  
  <pre><code>Team1 = ["Red", 10]
  Team2 = ["Green", 5]
  Team3 = ["Blue", 6]
  Team4 = ["Yellow", 8]
  Team5 = ["Purple", 9]
  Team6 = ["Brown", 4]
  
  TeamList = [Team1, Team2, Team3, Team4, Team5, Team6]
  </code></pre>
  
  <p>I want to make a two-dimensional list of difference in scores between each pair of teams.
  The output can be like this:

  <p>What is the easiest way to do this? Thanks :)</p>
