Ideally, the WebDriver service should stop once your script ends due to this code.
However if you want Chrome and ChromeDriver to stay open afterwards, you can add the experimental option detach
when initializing the chromedriver.
Through Selenium-Python client you can:
from selenium import webdriver
options = webdriver.ChromeOptions()
options.add_experimental_option("detach", True)
driver = webdriver.Chrome(chrome_options=options, executable_path=r'C:\WebDrivers\chromedriver.exe')
driver.get('https://www.google.com/')
