使用Selenium从Google下拉菜单中选择时出现问题(Python)

from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC

# 初始化浏览器驱动
driver = webdriver.Chrome()

# 打开Google首页
driver.get("https://www.google.com")

# 定位搜索框
search_box = driver.find_element_by_name("q")

# 输入搜索关键词
search_box.send_keys("关键词")

# 等待下拉菜单元素出现
dropdown_menu = WebDriverWait(driver, 10).until(
    EC.visibility_of_element_located((By.CLASS_NAME, "sbl1"))
)

# 选择下拉菜单中的选项
dropdown_menu.click()

# 关闭浏览器
driver.quit()

# 等待下拉菜单元素出现
dropdown_menu = WebDriverWait(driver, 10).until(
    EC.presence_of_element_located((By.CLASS_NAME, "sbl1"))
)

# 执行JavaScript代码，展开下拉菜单
driver.execute_script("arguments[0].style.display = 'block';", dropdown_menu)

# 选择下拉菜单中的选项
dropdown_menu.click()

# 使用XPath定位下拉菜单元素
dropdown_menu = WebDriverWait(driver, 10).until(
    EC.visibility_of_element_located((By.XPATH, "//ul[@role='listbox']/li[1]"))
)

# 选择下拉菜单中的选项
dropdown_menu.click()
