python selinium CSS_SELECTOR error

Question

I am trying to automate login to a web cite with selenium and python.

driver = webdriver.Firefox ()
driver.get (page)

this line

WebDriverWait (driver, 10).until( EC.presence_of_element_located (By.CSS_SELECTOR("#top-login-uname")))

produces the following error

WebDriverWait (driver, 10).until( EC.presence_of_element_located (By.CSS_SELECTOR("#top-login-uname")))
TypeError: 'str' object is not callable

the argument to CSS_SELECTOR seems to be correct...
I able to find the line with Firefox search line.

In Python you should use

EC.presence_of_element_located((By.CSS_SELECTOR, "#top-login-uname")))

Note that EC.presence_of_element_located() should accept tuple of by and value

TypeError: 'str' object is not callable is generated because By.CSS_SELECTOR stands for a simple string 'css selector'
