What makes me snarky is the replacing of<p><pre><code>    &#x27;%s %s&#x27; % (&#x27;one&#x27;, &#x27;two&#x27;)
</code></pre>
With<p><pre><code>    &#x27;%s %s&#x27;.format(&#x27;one&#x27;, &#x27;two&#x27;)
</code></pre>
The latter is just more annoying to type. Stupid argument I know but I find myself grumbling to myself every time...
