title: How to replace default values in the text field using selenium python?
body: <p>I know how to send keys into a blank field as follows:</p>
  
  <pre><code>from selenium import webdriver
  from selenium.webdriver.common.keys import Keys
  
  browser = webdriver.Firefox()
  url = 'https://www.aircanada.com/en/'
  browser.get(url)
  browser.find_element_by_id('departure1').send_keys('28/03/2014')
  </code></pre>
  
  <p>However, since the field already has default value 'DD/MM/YYYY', how can I replace that field value with my value (i.e., '28/03/2014')</p>
