Remove an item in list and get a new list?
<p>I saw there are several topics on removing items from a list, including using <code>remove()</code>, <code>pop()</code>, and <code>del</code>. But none of these is what I am looking for, since I want to get a new list when the items are removed. For example, I want to do this:</p>

<pre><code>a = [1, 2, 3, 4, 5, 6]
&lt;fill in &gt;       # This step somehow removes the third item and get a new list b and let
b = [1, 2, 4, 5, 6]
</code></pre>

<p>How can I do this?</p>
