Creating a list of tuples from a list
<p>I had a list, for example:</p>

<pre><code>data=['January', 'February', 'March',
      2007, 2008, 2009,
      'value1', 'value2', 'value3']
</code></pre>

<p>Now I need to create the list of tuples in the following format</p>

<pre><code>[('January', 2007,'value1'),('February', '2007','value2'),('March', 2007,'value3'),
('January', 2008,'value1'),('February', 2008,'value2'),('March', 2008,'value3'),
('January', 2009,'value1'),('February', 2009,'value2'),('March', 2009,'value3')] 
</code></pre>

<p>Please let me know the concept</p>
