title: Selenium, Trying to Find an Element [Python]
body: <p>I am trying type the username and password into my University mail using <code>Selenium</code> module. This is the id's attribute value that I'm trying to locate:</p>
  
  <p><code>&lt;input id="ContentPlaceHolder1_UsernameTextBox" name="username" tabindex="1" placeholder="FAU Net ID" value="" autocomplete="false" type="text"&gt;</code></p>
  
  <p>Here's how I'm trying to find it in my program:</p>
  
  <p><code>userElem = browser.find_element_by_id('ContentPlaceHolder1_UsernameTextBox')</code></p>
  
  <p>But this is the error that I'm running into:</p>
  
  <p>Exception -:</p>
  
  <pre><code>Traceback (most recent call last):
    File "&lt;pyshell#10&gt;", line 1, in &lt;module&gt;
      emailElem = browser.find_element_by_id('ContentPlaceHolder1_UsernameTextBox')
    File "C:\Python\Python35\lib\site-packages\selenium\webdriver\remote\webdriver.py", line 269, in find_element_by_id
      return self.find_element(by=By.ID, value=id_)
    File "C:\Python\Python35\lib\site-packages\selenium\webdriver\remote\webdriver.py", line 752, in find_element
      'value': value})['value']
    File "C:\Python\Python35\lib\site-packages\selenium\webdriver\remote\webdriver.py", line 236, in execute
      self.error_handler.check_response(response)
  
    File "C:\Python\Python35\lib\site-packages\selenium\webdriver\remote\errorhandler.py", line 192, in check_response
      raise exception_class(message, screen, stacktrace)
  selenium.common.exceptions.NoSuchElementException: Message: Unable to locate element: [id="ContentPlaceHolder1_UsernameTextBox"]
  </code></pre>
  
  <p>Thanks and any help would be greatly appreciated.</p>
