swap one element list to int
<p><code>a = [{43:123}, {3:103}, {36:103}, {2:102}, {23:100}]</code></p>

<p>How can I extract id from it when each of the keys is id and value means a number of points.
I tried use this:</p>

<pre><code>for b in a: 
     print a[i].keys()
     i+=1
</code></pre>

<p>Python result is a list, but I need integer type. eg 
<code>print a[2].keys()</code> result <code>[36]</code> and I need 36 which is int. Thx</p>
