# 打开 IMDb 网站
driver.get("https://www.imdb.com/")

# 获取前 10 部电影的标题和评分
titles = []
ratings = []
for i in range(1, 11):
    # 查找标题元素
    title_element = driver.find_element_by_xpath(f"(//h3)[{i}]/a")
    # 读标题
    title = title_element.text

    # 查找评分元素
    rating_element = driver.find_element_by_xpath(f"(//strong)[{i}]")
    # 读评分
    rating = rating_element.text

    titles.append(title)
    ratings.append(rating)

# 打印结果
for title, rating in zip(titles, ratings):
    print(f"{title}: {rating}")
