Get cell by column name using xlrd
<p>If I have two rows in an excel (.xls) sheet, like a key-value pair, is there a way to get the value (row1) by entering in the key (row0) in xlrd?</p>

<p>For example, if I have <code>(0,0) = COLOR</code> and <code>(1,0) = RED</code>, how would I do something like:</p>

<pre><code>value = sh.col_values("COLOR") ?
</code></pre>

<p>The closest I have been able to find is <code>sh.col_values(int)</code>, but that only allows me to enter in an index.</p>
