zipping a python dict of lists
<p>I have a python dictionary of type defaultdict(list)
This dictionary is something like this:</p>

<pre><code>a = {1:[1,2,3,4],2:[5,6,7,8]....n:[some 4 elements]}
</code></pre>

<p>So basically it has n keys which has a list as values and all the list are of same lenght.
Now, i want to build a list which has something like this.</p>

<pre><code>[[1,5,...first element of all the list], [2,6.. second element of all the list]... and so on]
</code></pre>

<p>Soo basically how do i get the kth value from all the keys.. Is there a pythonic way to do this.. ??
THanks</p>
