add_experimental_option() missing 1 required positional argument: 'value'

Question

I used the following code according to this post Set chrome.prefs with python binding for selenium in chromedriver

chroptions = webdriver.ChromeOptions

chroptions.add_experimental_option('prefs',{'download.default_directory' : 'C:\\Users\\elek2'})

browser = webdriver.Chrome(executable_path ='C:\\Users\\elek2\\AppData\\Local\\chromedriver.exe', chrome_options = chroptions)

and I get this error:

TypeError: add_experimental_option() missing 1 required positional argument: 'value'

What am I doing wrong...

You didn't pass an argument called `'value'` into `add_experimental_option()` function — Laszlowaty, Oct 15 '15 at 14:37
Sorry, that doesn't clarify a lot... isn't {'download.default_directory' : 'C:\\Users\\elek2'} a value? — Helena K, Oct 15 '15 at 14:40

You need to create an instance of Options. Currently you're just accessing the class itself.

chroptions = webdriver.ChromeOptions()
