Python Selenium Webdriver: How to avoid headless Chrome and run in new window on Windows 10 instead Ask

[Alexander Farr]

I would like to observe what my Selenium webdriver program is doing. However, I currently use headless Chrome and it does not work in its own window. How could I run the program in a window I can see?

This is the code I use:

from selenium import webdriver
from webdriver_manager.chrome import ChromeDriverManager
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.support.ui import Select
from selenium.webdriver.chrome.options import Options
import os
import time
def acxiom_DD_formfill(title, firstname, middlename, lastname, suffix, email):
    chrome_options = Options()
    chrome_options.add_argument('--no-sandbox')
    chrome_options.add_argument('--headless')
    chrome_options.add_argument('--disable-dev-shm-usage')
    chrome_options.add_experimental_option("excludeSwitches", ["enable-automation"])
    chrome_options.add_experimental_option('useAutomationExtension', False)
    driver = webdriver.Chrome(options=chrome_options)
    #driver = webdriver.Chrome('/usr/lib/chromium-browser/chromedriver', options=chrome_options)
    driver.set_page_load_timeout(10)
    driver.set_window_size(1124, 850) # set browser size.
    # link to data delete form
    print("opening data delete form")
    driver.get("https://isapps.acxiom.com/optout/optout.aspx#section8")
    #Select opt out segment: Following option values: "Mail", "Telemarketing", "Email"
    ele = driver.find_element_by_xpath("//select[@id='OptOutChoices2']/option[@value='Mail']") 
    driver.execute_script("arguments[0].click()",ele)
    print("dropdown selected")
    time.sleep(4)
    driver.quit()
    return None

When not including following line: #chrome_options.add_argument('--headless')

I get this error:

Traceback (most recent call last):

  (The process started from chrome location /usr/bin/chromium-browser is no longer running, so ChromeDriver is assuming that Chrome has crashed.)

Thank you for your help!
