Two forward slashes in Python
<p>I came across this sample of code from a <a href="http://en.wikipedia.org/wiki/Radix_sort#Example_in_Python" rel="nofollow">radix sort</a>:</p>

<pre class="lang-py prettyprint-override"><code>def getDigit(num, base, digit_num):
    # pulls the selected digit
    return (num // base ** digit_num) % base
</code></pre>

<p>What does the '<code>//</code>' do in Python?</p>
