How to multiply pair-wise tuple list
<p>I know how to multiply the elements of a single tuple:</p>

<pre><code>tup = (2,3)
tup[0]*tup[1]
6
</code></pre>

<p>My question is how do you multiply the elements of several tuples using a for loop?</p>

<p>example: How do I get <code>x = (4,5,6)</code> when <code>x = ((2,2), (5,1), (3,2))</code>?</p>
