Python - Intersection of two lists of lists
<p>These are my two lists;</p>

<pre><code>k = [[1, 2], [4], [5, 6, 2], [1, 2], [3], [4], [5,9]]
kDash = [[1, 2], [4], [5, 6, 2], [1, 2], [3], [4], [5,6], [1,2]]
</code></pre>

<p>My output should be the following;</p>

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

<p>how can I get to this output?</p>

<p>thank you in advance</p>
