combine list elements
<p>How can I merge/combine two or three elements of a list. For instance, if there are two elements, the list 'l'</p>

<pre><code>l = [(a,b,c,d,e),(1,2,3,4,5)]
</code></pre>

<p>is merged into</p>

<pre><code>[(a,1),(b,2),(c,3),(d,4),(e,5)]
</code></pre>

<p>however if there are three elements</p>

<pre><code>l = [(a,b,c,d,e),(1,2,3,4,5),(I,II,II,IV,V)] 
</code></pre>

<p>the list is converted into </p>

<pre><code>[(a,1,I),(b,2,II),(c,3,III),(d,4,Iv),(e,5,V)]
</code></pre>

<p>Many thanks in advance.</p>
