如何使用 Python 和 Selenium 检索视频在 Youtube 上发布的日期

Question

我在 python 和 selenium 中制作了一个脚本，可以在 youtube 上进行搜索。完全加载后，我只能从结果中获取所有标题。有没有我可以集成的任何代码行来获取发布日期？

这是我的代码：

def youTube():
    term = 'bitcoin'
    tit = []
    
    d = webdriver.Firefox()
    d.get('https://www.youtube.com/results?search_query='+term+'&sp=CAISAhAB')
    sleep(3)
    
    d.find_element_by_xpath("//*[contains(text(), 'Accetto')]").click()
    sleep(2)
    
    scrollHeight = d.execute_script("return window.scrollMaxY")
    print(scrollHeight)
    scrolled_pages = 0
    # while we have not reached the max scrollHeight
    while d.execute_script("return window.pageYOffset") < 3000:
        d.execute_script("window.scrollByPages(1)")
        scrolled_pages += 1
        sleep(0.2)
    for my_elem in WebDriverWait(d, 20).until(EC.visibility_of_all_elements_located((By.XPATH, "//yt-formatted-string[@class='style-scope ytd-video-renderer' and @aria-label]"))):
        tit.append(my_elem.text)

当视频在 Youtube using Python and you can use the following 上发布时检索 date/time：

代码块：

driver.get("https://www.youtube.com/results?search_query=%27+term+%27&sp=CAISAhAB")
print([my_elem.get_attribute("innerHTML") for my_elem in WebDriverWait(driver, 20).until(EC.visibility_of_all_elements_located((By.XPATH, "//div[@id='metadata-line' and @class='style-scope ytd-video-meta-block']////following::span[2][contains(., 'hours') or contains(., 'day')]")))])

控制台输出：

['2 hours ago', '2 hours ago', '3 hours ago', 'Streamed 3 hours ago', 'Streamed 3 hours ago', '5 hours ago', 'Streamed 6 hours ago', '6 hours ago', '6 hours ago', '7 hours ago', '8 hours ago', 'Streamed 8 hours ago', '9 hours ago', 'Streamed 10 hours ago', '11 hours ago']
