Swap position of entities in the list
<p>I have a following example list</p>

<pre><code>   x= [['True_304', 'false_2'], ['True_702', 'false_2_1'], ['True_204', 'false_222_2']]
</code></pre>

<p>I would like to swap the positions of entities so that the second entity is first and first one is second. Basically, something like: </p>

<pre><code>   x= [['false_2', 'True_304'], ['false_2_1', 'True_702'], ['false_222_2', 'True_204']]
</code></pre>

<p>Is there any easier way to do this? Any ideas would be helpful. Thanks.</p>
