creating flat list from two lists
<p>Given a list of values:</p>

<pre><code>data = [100, 80, 200, 20, 300, 100, 400, 40, 500, 120, 600, 60]
</code></pre>

<p>I want to extract the first two and the last two values, and create a new list. Unfortunately, the way I'm doing things right now, I get a list which contains two lists:</p>

<pre><code>bla = [data[0:2], data[-2:]]

print bla
 [[100, 80], [600, 60]]
</code></pre>

<p>Instead I would like to get this:</p>

<pre><code>[100, 80, 600, 60]
</code></pre>

<p>Is there an easy way of doing this? </p>

<p>(this question is somewhat related to <a href="http://stackoverflow.com/questions/1818763/creating-new-list-with-values-from-two-prior-lists">this question</a>, but I still think it's different enough)</p>
