Answer 1

注意-您的订阅文本框位于不同的< code>iframe中，要使用该< code>iframe，您需要首先切换到该< code>iframe。

尝试下面的代码，如果您需要更多澄清，请告诉我-

from selenium import webdriver
from selenium.webdriver.chrome.options import Options
from selenium.webdriver.common.by import By
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver import ActionChains
import time

chrome_options = Options()
chrome_options.add_argument("--window-size=1920x1080")

driver = webdriver.Chrome(options=chrome_options)

wait = WebDriverWait(driver, 5)
action = ActionChains(driver)

driver.get('https://dataengweekly.com/')

iframe = driver.find_element_by_xpath('//iframe')
driver.switch_to.frame(iframe)

email_input = wait.until(EC.presence_of_element_located((By.XPATH, "//input[@type='email']")))
action.move_to_element(email_input).click().send_keys("[e-mail]").perform()

driver.find_element_by_css_selector('button.subscribe-btn').click()
time.sleep(2)
