title: In python, selenium, how do I set the error messages for a wait?
body: <p>I have the following code:</p>
  
  <pre><code>WebDriverWait(self.driver, 20).until(expected_conditions.element_to_be_clickable(click))
  </code></pre>
  
  <p>Now this sometimes fails and I know why it fails.  But the error gives me </p>
  
  <pre><code>TimeoutException: Message: 
  </code></pre>
  
  <p>Which is useless.  Can I possibly set this message? </p>
