  ...
  &lt;/div&gt;
  </code></pre>
  
  <p>selection:</p>
  
  <pre class="lang-py prettyprint-override"><code>last_named_class = result.find_element_by_class_name('result-list-entry__data')
  </code></pre>
  
  <p>Current result(error):</p>
  
  <blockquote>
    <p>selenium.common.exceptions.NoSuchElementException: Message: no such
