how to make a list of lists in to dictionary of tuples
<p>I had <strong>list of lists</strong> for example</p>

<pre><code>res = [[None,'A','B'],[19980228, 'd1', 't1'],[19980302, 'd2', 't2'],[19980303, 'd3', 't3']]
</code></pre>

<p>Now i need to frame the above result as <strong>dictionary of list of tuples</strong> like</p>

<pre><code>{'A': [(19980228, 'd1'), (19980302, 'd2'), (19980303, 'd3')], 
 'B': [(19980228, 't1'), (19980302, 't2'), (19980303, 't3')]}
</code></pre>

<p>Please let this me know this concept, Thanks in advance.</p>
