NameError：未定义名称“options”

问：

我正在使用 and 如何相应地设置此代码？代码我写了：selenium 4.14.0mozilla 119.0GeckoDriver-v0.33.0

    from selenium.webdriver.firefox.service import Service
    from selenium.webdriver.firefox.options import Options
    from selenium.webdriver.common.by import By
    from selenium.webdriver.common.keys import Keys
    import time
    def instagram_login(username, password):
    options = Options()
    options.headless = True
    service = Service('C:\geckodriver\geckodriver.exe')
    driver = webdriver.Firefox(service=service, options=options)
    driver.get('https://www.instagram.com/')
    time.sleep(2)
    username_input = driver.find_element(By.NAME, 'username')
    username_input.send_keys(username)
    username_input.send_keys(Keys.ENTER)
    time.sleep(2)
    password_input = driver.find_element(By.NAME, 'password')
    password_input.send_keys(password)
    password_input.send_keys(Keys.ENTER)
    time.sleep(2)
    driver.quit()
    username = ''
    password = ''
    instagram_login(username, password)

当我运行代码时，我遇到以下错误：

options.headless = True NameError: name 'options' is not defined. Did you mean: 'Options'?

和

service = Service('C:\geckodriver\geckodriver.exe') SyntaxWarning: invalid escape sequence '\g'
