comparing lists at a previous index
<p>I have got 2 lists for which I would like to compare to one index before :</p>

<pre><code>for (min,max) in zip(csv_parse(2010)['min'],csv_parse(2010)['max']):
</code></pre>

<p>basically I would like something like this :</p>

<p><strong>if min > min(back one increment) and max &lt; max (back on increment)</strong></p>

<p>then, do something .</p>

<p>Thanks !</p>
