join list of lists in python
<p>Is the a short syntax for joining a list of lists into a single list( or iterator) in python?</p>

<p>For example I have a list as follows and I want to iterate over a,b and c.  </p>

<pre><code>x = [["a","b"], ["c"]]
</code></pre>

<p>The best I can come up with is as follows.</p>

<pre><code>result = []
[ result.extend(el) for el in x] 

for el in result:
  print el
</code></pre>
