<h3 id="q1-draw">Q1: Draw</h3>


<p>The <code>draw</code> function takes a list <code>hand</code> and a list of unique non-negative
integers <code>positions</code> that are all less than the length of <code>hand</code>. It removes
<code>hand[p]</code> for each <code>p</code> in <code>positions</code> and returns a list of those elements in
the order they appeared in <code>hand</code> (not the order they appeared in <code>positions</code>).</p>

<p>Fill in each blank with one of these names: <code>list</code>, <code>map</code>, <code>filter</code>, <code>reverse</code>,
<code>reversed</code>, <code>sort</code>, <code>sorted</code>, <code>append</code>, <code>insert</code>, <code>index</code>, <code>remove</code>, <code>pop</code>,
<code>zip</code>, or <code>sum</code>. See the <a href="https://docs.python.org/3/library/functions.html">built-in functions</a> and
<a href="https://docs.python.org/3/tutorial/datastructures.html#more-on-lists">list methods</a>
documentation for descriptions of what these do.</p>

<p><strong>Discussion Time:</strong> Before writing anything, talk as a group about what
process you'll implement in order to make sure the right cards are removed and
returned. Try not to guess-and-check! The purpose of discussion is for you to
try to solve problems without the help of an interpreter checking your work.</p>
