What is the second argument in the code used to convert from string to int in Python?
<p>I have found some strange syntax in python:</p>

<pre><code>int(array[0], 32)
</code></pre>

<p><code>array[0]</code> is some string, but what exactly is the second parameter for?  And can somebody please explain this <code>int()</code> syntax, is it function or casting? </p>
