启动功能时

def run(driver_path):
    driver = webdriver.Chrome(executable_path=driver_path)
    driver.get('https://tproger.ru/quiz/real-programmer/')
    button = driver.find_element_by_class_name("quiz_button")
    button.click()
run(driver_path)

我收到这样的错误：

def run(driver_path):
    driver = webdriver.Chrome(executable_path=driver_path)
    driver.get('https://tproger.ru/quiz/real-programmer/')
    button = driver.find_element_by_class_name("quiz_button")
    button.click()
run(driver_path)

...但我不明白为什么。

我正在为我的 Chrome 版本使用最新版本的WebDriver 。我不知道为什么我得到

<ipython-input-27-c5a7960e105f>:6: DeprecationWarning: executable_path has been deprecated, please pass in a Service object
  driver = webdriver.Chrome(executable_path=driver_path)
<ipython-input-27-c5a7960e105f>:10: DeprecationWarning: find_element_by_* commands are deprecated. Please use find_element() instead
  button = driver.find_element_by_class_name("quiz_button")

...当文档中存在该命令时。

我正在使用以下代码运行 python 3.9。当我运行脚本时，我收到错误消息。不知道我错过了什么。该元素称为用户名。

使用 Selenium，我无法在 Udemy 网站上找到“电子邮件”元素。

这是我尝试过的：

browser.get('https://www.udemy.com/join/login-popup/')
browser.implicitly_wait(5)

email = browser.find_element(By.ID, 'email--1')
print(email)

但NoSuchElementException据我所知，它给出了“email”元素甚至不在 iframe 中的情况。

那么，我怎样才能找到这个特定的元素呢？
