Concatenating two lists : <p>I have a list of lists that looks as follows (I hope I'm right when I said list of lists):</p>

<pre><code>['[175', '178', '182', '172', '167', '164]', "['b']"]
</code></pre>

<p>How can I concatenate the two lists? That is, having a list that looks as follows:</p>

<pre><code>[175, 178, 182, 172, 167, 164, b]
</code></pre>

<p>Any thoughts?</p>

<p>Thanks.</p>
