How do I insert a list into another list in python?
<p>I have two lists:</p>

<pre><code>A = [1,2,3]
B = [4,5,6]
</code></pre>

<p>Is there an elegant way to insert B into A at an arbitrary postion?</p>

<p>Hypothetical output:</p>

<pre><code>[1,4,5,6,2,3]
</code></pre>

<p>Obviously I could iterate through B and insert them one at a time, but I figured there was a better way.</p>
