Clear old text and input new text in Python Selenium

Question

I am using Selenium to clear old text in a text area before input new text in a web browser. This is my code:

MY_UDP_SESSION = 32768
elem = driver.find_element_by_id("udp-session-quota").clear()
time.sleep(1)
elem.send_keys(MY_UDP_SESSION)

but I see this error:

'NoneType' object has no attribute 'send_keys'

clear()

clear() clears the text if it's a text entry element and is defined as:

def clear(self):
    """Clears the text if it's a text entry element."""
    self._execute(Command.CLEAR_ELEMENT)

As clear() doesn't returns anything hence as per your line of code:

elem = driver.find_element_by_id("udp-session-quota").clear()

elem is assigned as null i.e. NoneType. Moving forward when you try to invoke send_keys() on elem:

elem.send_keys(MY_UDP_SESSION)

You see the error.

Once the WebElement is returned then you can invoke clear() and send_keys() as follows:

MY_UDP_SESSION = "32768"
elem = driver.find_element_by_id("udp-session-quota")
elem.clear()
elem.send_keys(MY_UDP_SESSION)
