title: Python: Return 2 ints for index in 2D lists given item
body: <p>I've been tinkering in python this week and I got stuck on something. <br>
  If I had a 2D list like this:</p>
  
  <pre><code>myList = [[1,2],[3,4],[5,6]]
  </code></pre>
  
  <p>and I did this</p>
  
  <pre><code>&gt;&gt;&gt;myList.index([3,4])
  </code></pre>
  
  <p>it would return</p>
  
  <pre><code>1
  </code></pre>
  
  <p>However, I want the index of something in side one of the lists, like this</p>
  
  <pre><code>    &gt;&gt;&gt;myList.index(3)
  </code></pre>
  
  <p>and it would return </p>
  
  <pre><code>1, 0
  </code></pre>
  
  <p>Is there anything that can do this? </p>
  
  <p>Cheers</p>
