Python Selenium Explicit WebDriverWait function only works with presence_of_element_located

I am trying to use Selenium WebDriverWait in Python to wait for items to load on a webpage , however, using any expected condition apart from presence_of_element_located seems to result in the error

selenium.common.exceptions.WebDriverException: Message: SyntaxError: missing ) in parenthetical

I thought it might be linked to the site I was trying against , however I get the same error on any site - see snippit below where I have replaced presence_of_element_located with visibility_of_element_located and am trying to confirm visibility of the search box on python.org.

from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.common.keys import Keys

driver = webdriver.Firefox()
driver.get("http://www.python.org")

try:
    element = WebDriverWait(driver, 5).until(EC.visibility_of_element_located((By.NAME,"q")))
    element.send_keys("pycon")
    element.send_keys(Keys.RETURN)
finally:
    driver.quit()

The Full stack trace is as below , Any help would be appreciated !

selenium.common.exceptions.WebDriverException: Message: SyntaxError: missing ) in parenthetical

Update - > After a few comments below i have done some testing on versions and browsers and this issue seems isolated to Python 3 and Firefox , the script works with Python 2.7 and works on both versions of python for Chrome webdriver .

These minor changes work for me.

  1. visibility_of_element_located ===> presence_of_element_located
  2. driver.quit() ===> driver.close()

See the following:

from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.common.keys import Keys

driver = webdriver.Firefox()
driver.get("http://www.python.org")

try:
    element = WebDriverWait(driver, 5).until(EC.presence_of_element_located((By.NAME,"q")))
    element.send_keys("pycon")
    element.send_keys(Keys.RETURN)
finally:
    driver.close()
