&#x27;+&#x27; works great as a concatenation operator, so long as you don&#x27;t ever try to implicitly convert the values. Case in point - Python:<p><pre><code>  &gt;&gt;&gt; 1+2
  3
  &gt;&gt;&gt; &quot;1&quot;+&quot;2&quot;
  &#x27;12&#x27;
  &gt;&gt;&gt; &quot;1&quot;+2
  Traceback (most recent call last):
    File &quot;&lt;stdin&gt;&quot;, line 1, in &lt;module&gt;
  TypeError: Can&#x27;t convert &#x27;int&#x27; object to str implicitly</code></pre>
