selenium 'nonetype' object has no attribute 'send_keys'

Question

title='this is the title'

I want to locate with python/selenium, within a web page, this line:

<input id="subject" name="subject" maxlength="50" value="" class="nude error" type="text">

I use this code with python-selenium (under Debian):

title = driver.find_element_by_id("subject").clear()
title.send_keys(title) 

I got the following error:

Traceback (most recent call last):

  File "./basic0", line 49, in <module>
titre.send_keys(title)

AttributeError: 'NoneType' object has no attribute 'send_keys'

note:when the script stops because of this error, the mouse cursor is at the right at place within the web page; but I cannot find a way to send_keys to fill in the input

I also tried:

title = driver.find_element_by_xpath("div[contains(text(),'subject')]")

title = driver.find_element_by_xpath("//form[input/@id='subject']")

title = driver.find_element_by_xpath("//form[input[@name='subject']")

but it does not work; furthermore the mouse cursor is not at the right place.

then I tried a later selenium version:

I completly purge python-selenium package under Debian (which is selenium v. 2.53) then

pip install selenium==3.3.1

This time, when I launch the script it says that geckodriver is missing: so,

wget https://github.com/mozilla/geckodriver/releases/download/v0.23.0/geckodriver-v0.23.0-linux32.tar.gz

tar -xvzf geckodriver-v0.23.0-linux32.tar.gz

chmod 755 geckodriver (I also tried 777)

mv geckodriver /usr/local/bin/ (so it's in my PATH)

now when I launch the script, here is the error message I got:

Traceback (most recent call last):

  File "./basic0", line 13, in <module>
driver = webdriver.Firefox()

  File "/usr/local/lib/python2.7/dist-packages/selenium/webdriver/firefox/webdriver.py", line 155, in __init__

selenium.common.exceptions.WebDriverException: Message: connection refuse

firefox window pops-up, and then shutdown when the script stops

Solution

You've assigned method call (clear()) which returns None to title variable while you need to define WebElement and call methods subsequently as

title = driver.find_element_by_id("subject")
title.clear()
title.send_keys("title")

I tried your solution and first got: "AttributeError: 'WebDriver' object has no attribute 'clear' ". I then removed title.clear(); it worked but filled the input in with 'title' instead of the variable content. I then tried driver.send_keys(title): it was ok. Now just wondering why clear() did not work. Thank you indeed!

@achille , I guess you tried driver.clear() instead of title.clear() (title should be object of type WebElement)
