Python: How to hide output Chrome messages in Selenium?

Question

What I want to do:

I want to open Chrome browser using Selenium ChromeDriver without the Chrome messages getting output to the console.

What I did:

from selenium import webdriver
driver = webdriver.Chrome(r'C:\Users\u1\Documents\scripts\chromedriver.exe')

Output:

C:\Users\u1\Documents\scripts>python test.py

DevTools listening on ws://127.0.0.1:50605/devtools/browser/11c9063a-44ce-4b39-9566-9e6c6270025c

I want to hide the output message "DevTools listening on..."

What I tried to solve this:

Using contextlib

from selenium import webdriver
import contextlib

with contextlib.redirect_stdout(None):
   driver = webdriver.Chrome(r'C:\Users\u1\Documents\scripts\chromedriver.exe')

Using devnull

from selenium import webdriver
import subprocess

devnull = subprocess.DEVNULL
subprocess.Popen(open_browser(), stdout=devnull, stderr=devnull)
def open_browser():
    driver = webdriver.Chrome(r'C:\Users\u1\Documents\scripts\chromedriver.exe')

Using log-level=3

chrome_options = Options()
chrome_options.add_argument("--log-level=3")
driver = webdriver.Chrome(r'C:\Users\u1\Documents\scripts\chromedriver.exe', chrome_options=chrome_options)

But still the message is getting displayed. How do I hide the output message "DevTools listening on..." in Python?

I already checked that answer. That answer did not solve this issue. So, I try to solve it in a different way. — Dipankar Nalui

Add this option to your driver and your problem will be solved:

options = webdriver.ChromeOptions()
options.add_experimental_option('excludeSwitches', ['enable-logging'])

similar question in DevTools listening on ws://127.0.0.1:57671/devtools/browser/8a586f7c-5f2c-4d10-8174-7a7bf50e49b5 with Selenium and Python.

the answer is:

base on Chanticleer in hide chromeDriver console in python

Locate and edit this file as follows: located at Lib\site-packages\selenium\webdriver\common\services.py in your Python folder.

Edit the Start() function by adding the creation flags this way: creationflags=CREATE_NO_WINDOW

from win32process import CREATE_NO_WINDOW

def start(self):
    """
    Starts the Service.

    :Exceptions:
     - WebDriverException : Raised either when it can't start the service
       or when it can't connect to the service
    """
    try:
        cmd = [self.path]
        cmd.extend(self.command_line_args())
        self.process = subprocess.Popen(cmd, env=self.env,
                                        close_fds=platform.system() != 'Windows',
                                        stdout=self.log_file, stderr=self.log_file, creationflags=CREATE_NO_WINDOW)
    except TypeError:
        raise

Works Perfectly for me (python3.7, selenium 3.141.0)

please give me credit to spending hours for searching the answer.

For me Full path is C:\Users\u1\AppData\Local\Programs\Python\Python37\Lib\site-packages\selenium\webdriver\common\service.py

Dipankar Nalui Over a year ago

It is service.py not services.py for me

Dipankar Nalui Over a year ago

I did as you answered. But I see this error from win32process import CREATE_NO_WINDOW ModuleNotFoundError: No module named 'win32process'

Dipankar Nalui Over a year ago

pip install win32process Gives me this error

Collecting win32process   Could not find a version that satisfies the requirement win32process (from versions: ) No matching distribution found for win32process

Those are chrome messages, so you need to set the options for the Chrome-Log Level to hide those messages, setting the log-level to --log-level=3 should be enough (only fatal log messages.

from selenium.webdriver.chrome.options import Options
[...]
chrome-options = Options()
chrome-options.add_argument("--log-level=3")
driver = webdriver.Chrome(chrome_options=chrome-options)

Also out of curiosity, might I ask why?

I already used this code. That message is still displayed. This does not solve my problem.

Dipankar Nalui Over a year ago

I googled and found this same solution earlier. Many people suggested this solution in stackoverflow. But this did not solve my problem. So, I wanted to solve it in a different way.

Bernhard Over a year ago

Thought that would help. btw I'd put the fact that you found a "solution" that worked for somebody else and that it did not work for you in the question with a link.

scavenger Over a year ago

this does not hide the message, neither does loglevel 0, 1 ,2 , 3 or 4

YoussefDir Over a year ago

@Dipankar you're right in that it doesn't hide "DevTools listening on ws://..." message but it still hides some other logs.

There is a way to modify the library selenium to solve this problem.

you can search directly with the next route, for modify the lines the that subprocess, this close the message that apper in the console.

you go to main folder In the route /venv/selenium/webdriver/common/service.py you modify the next lines, please you write this.

cmd = [self.path]
cmd.extend(self.command_line_args())
self.process = subprocess.Popen(cmd, stdin=PIPE, stdout=PIPE, 
                                stderr=PIPE, shell=False,
                               creationflags=0x08000000)

with this piece of code you will get the solution.

It might be written badly, but this is the only answer I've found that actually solves the problem. Go to venv\Lib\site-packages\selenium\webdriver\common\service.py and under the "_start_process" function search for the only subprocess.Popen... statement and change the "creationflags=self.creation_flags" for "creationflags=0x08000000".

passing --show-capture=no does the job
