I'm trying to run a python program that uses Selenium and Chrome to analyze data from some websites. The problem I'm having is that either Selenium or the Webdriver is flooding the console with output I don't care about and making it difficult to view my programs output. I've read many other threads about this with various driver options, but nothing seems to work. The best these options do is remove this:

But all of these remain:

Is there any way to get these removed as well? Here is my setup for the webdriver (I've tried enabling/disabling many combinations of these options in case something is conflicting, but that didn't help):
from selenium import webdriver
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities
options = webdriver.ChromeOptions()
options.binary_location = chrome_path
options.add_experimental_option('excludeSwitches', ['enable-logging'])
options.add_argument("--headless")
options.add_argument("--log-level=3")
options.add_argument("--window-size=1400x1080")
options.add_argument("--mute-audio")
options.add_argument("--no-sandbox")
options.add_argument("--disable-dev-shm-usage")
options.add_argument('--disable-extensions')
options.add_argument('--disable-gpu')
capa = DesiredCapabilities.CHROME
capa["pageLoadStrategy"] = "none"
browser = webdriver.Chrome(chrome_options=options,
desired_capabilities=capa,
executable_path=chromedriver_path)
Here are my versions:
python: 3.8.2
selenium: 3.141.0
chrome: 83.0.4103.61
chromedriver: 83.0.4103.39
To dismiss a popup, the method switch_to. alert(). dismiss() is used. To obtain the text on a popup, we have to use the switch_to.
As said before, Selenium WebDriver provides an API for automation test engineers to select options based on option values too, i.e., select_by_value (self, value). On our demo page, the first “Select your lang:” section is a form element implemented using select & option with value attribute. To select python using select_by_value method –
Running Python Selenium causes the ChromeDriver console window to appear. In this article, I will note how to hide it. Pay attention to the version. In older versions of Selenium, the methods described in this article may not work. You can hide the console window by directly rewriting the creationflags of the Service class. Written below.
Selenium Python bindings provides a simple API to write functional/acceptance tests using Selenium WebDriver. To open a webpage using Selenium Python, checkout – Navigating links using get method – Selenium Python. Just being able to go to places isn’t terribly useful.

this worked for me
chrome_options.add_argument("--log-level=3")
another answer suggested using "--log-level=OFF" however this didn't seem to work for me
You can send all logs to the void, as described in this question
import os
# Let python handle it
driver = webdriver.Chrome(service_log_path=os.devnull)
# The proper null device option for Windows
driver = webdriver.Chrome(service_log_path='NUL')
, or use the less documented 'silent mode' explained here
options.add_argument("--log-level=OFF")
Hope one of these helps!
