title: Selenium / Python switch webdriver from headless to window mode
body: <p>Is there any way to switch Chrome webdriver from headless mode to window mode?</p>
  
  <p>One thing that came to my mind is to 'switch' existing web driver to non-headless mode.
  Another idea: to create new instance of webdriver (this time non-headless) with some sort of 'state' from old one so the user operations can be executed. I don't know how to do or if it is possible though.</p>
  
  <pre><code>import os
  from selenium import webdriver
  from selenium.common.exceptions import NoSuchElementException,
  
  options = webdriver.ChromeOptions()
  options.add_argument('headless')
  driver = webdriver.Chrome(
      executable_path=os.path.join(os.getcwd(), 'chromedriver'),
      chrome_options=options,
      )
  driver.get('https://website.com')
  try:
      driver.find_element_by_xpath('//h1').click()
  except NoSuchElementException:
      print('You have to click it manually')
      # here I need Chrome browser
      # to be opened so that I can click a link
  print('The name of this thing is: ', end='')
  print(driver.find_element_by_xpath("//h1[@class='name']").text)
  </code></pre>
