For-loop over several variables from a single list
<p>I'm trying to create a loop like this</p>

<pre><code>newList = [a + b for a,b in list[::2], list[1::2]]
</code></pre>

<p>meaning, take two consecutive entries from a list, do something with them and put the into a new list.</p>

<p>How would that work? </p>
