How to change the User Agent using Selenium and Python

I am having an error when changing the web driver user agent in Python using selenium.

Here is my code:

import requests
import json
from selenium import webdriver
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities
driver = webdriver.Chrome(driver_path) driver.execute_cdp_cmd('Network.setUserAgentOverride', {"userAgent": 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/83.0.4103.97 Safari/537.36'})
#Error is on line above

Here is my error:

>>> driver = webdriver.Chrome(driver_path) driver.execute_cdp_cmd('Network.setUserAgentOverride', {"userAgent":"python 3.7", "platform":"Windows"}) 
  File "<stdin>", line 1
    driver = webdriver.Chrome(driver_path) driver.execute_cdp_cmd('Network.setUserAgentOverride', {"userAgent":"python 3.7", "platform":"Windows"})```

follow the steps below :

1- you can use produce fake user-agent library in every request for use it

add to code :

from fake_useragent import UserAgent

2- and then in terminal do this :

 pip install fake_useragent

3- use in code : for example

chrome_options = webdriver.ChromeOptions()
chrome_options.add_argument(f'user-agent={userAgent}')
ua = UserAgent()
userAgent = ua.random
print(userAgent)
driver = webdriver.Chrome(options=chrome_options,executable_path=r"strin path 
chrome driver")

and if you want from static user-agent use this code :

chrome_options = webdriver.ChromeOptions()
chrome_options.add_argument('--user-agent="Mozilla/5.0 (Windows NT 6.1; 
WOW64; rv:50.0) Gecko/20100101 Firefox/50.0"')
driver = webdriver.Chrome(chrome_options=chrome_options)

Your code is just perfect. You simply have to write the line of code to change the in the next line. As an example:

  • Code Block:

    from selenium import webdriver

driver = webdriver.Chrome(executable_path=r'C:\WebDrivers\chromedriver.exe')
print(driver.execute_script("return navigator.userAgent;"))
# Setting user agent as Chrome/83.0.4103.97
driver.execute_cdp_cmd('Network.setUserAgentOverride', {"userAgent": 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/83.0.4103.97 Safari/537.36'})
print(driver.execute_script("return navigator.userAgent;"))
# Setting user agent as Chrome/83.0.4103.53
driver.execute_cdp_cmd('Network.setUserAgentOverride', {"userAgent": 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/83.0.4103.53 Safari/537.36'})
print(driver.execute_script("return navigator.userAgent;"))
driver.get('https://www.httpbin.org/headers')

  • Console Output:

    Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/83.0.4103.106 Safari/537.36
Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/83.0.4103.97 Safari/537.36
Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/83.0.4103.53 Safari/537.36

You should use driver options:

from selenium.webdriver.chrome.options import Options

options = Options()
options.add_argument("user-agent=[user-agent string]")

driver = webdriver.Chrome(executable_path='path', chrome_options=options)
