title: How can I select the last drop-down option in selenium with python?
body: <p>I have a drop-down menu as follows in HTML:</p>
  
  <pre><code>&lt;select id="TargetRadius" name="TargetRadius"&gt;
      &lt;option value="1" selected="true"&gt;1&lt;/option&gt;
      &lt;option value="11"&gt;11&lt;/option&gt;
      &lt;option value="15"&gt;15&lt;/option&gt;
      &lt;option value="18"&gt;18&lt;/option&gt;
  &lt;/select&gt;
  </code></pre>
  
  <p>I want to choose the last option.  However, I am looping this, and the values change for each loop.  How can I choose the last option without referencing the value of the "option" tag?</p>
