Python, bringing two list elements together : <p>I have a list like this:</p>

<pre><code>['PHE', '45', 'HIS', '46', 'HIS', '46', 'HIS', '46', 'HIS', '46', 'HIS', '46']
</code></pre>

<p>I want it to turn into</p>

<pre><code>['PHE 45', 'HIS '46', 'HIS '46'] # it goes on like that
</code></pre>

<p>how can I merge consecutive list elements to eachother?</p>
