Does anyone know what this loop does : <p>Suuupppeeeeerrrrrr noob question, </p>

<p>I am trying to deconstruct some python code, and I can figure out what this line does.  I know it cycles thru potentially 28 iterations but I can't figure out what the i%len does to question.</p>

<pre><code>for i in range(t, t + 28):
    transmission.append(question[i%len(question)])
</code></pre>

<p>Thanks for your help.</p>
