title: League fixture generator in python
body: <p>I would like to write a League Fixture generator in python, but I can't. Here is the details:</p>
  
  <p>There is a dynamic list of teams like <code>teams = ["Team1", "Team2", "Team3", "Team4"]</code>.
  How can I generate a fixture_weekx list from the teams list? For example:</p>
  
  <pre><code>fixture_week1 = ["Team1", "Team2", "Team3", "Team4"]
  fixture_week2 = ["Team1", "Team3", "Team2", "Team4"]
  fixture_week2 = ["Team1", "Team4", "Team2", "Team3"]
  
  #Return matches:
  fixture_week1 = ["Team2", "Team1", "Team4", "Team3"]
  fixture_week2 = ["Team3", "Team1", "Team4", "Team2"]
  fixture_week2 = ["Team4", "Team1", "Team3", "Team2"]
  </code></pre>
  
  <p>Any idea?</p>
