Selenium chrome use multiple add_experimental_option

Question

I want to use 2 experimental options on my selenium chromedriver project, but I don't get enough information about the "add_experimental_option" function, I want to use 2 experimental options "prefs" and "debuggerAddress", and when I try to run it, it gets error, I can only use one of them, how can I use both of them?

opt = Options()
opt.add_experimental_option("debuggerAddress", "127.0.0.1:9222")
opt.add_experimental_option("prefs", { \
    "profile.managed_default_content_settings.images": 2
})

error messages

Answer 1

ChromeOptions objects

• prefs [type: dictionary]: A dictionary with each entry consisting of the name of the preference and its value. These preferences are only applied to the user profile in use.

• debuggerAddress [type: string]: An address of a Chrome debugger server to connect to, in the form of <hostname/ip:port>, e.g. '127.0.0.1:38947'

You can add both the experimental_option as follows:

opt = webdriver.ChromeOptions()
prefs = {"profile.managed_default_content_settings.images" : 2}
opt.add_experimental_option("prefs", prefs)
opt.add_experimental_option("debuggerAddress", "127.0.0.1:9222")
driver = webdriver.Chrome(executable_path=r'C:\path\to\chromedriver.exe', options=opt, service_log_path='NUL')
