Answer 1

您试图访问的元素在iframe中
因此，为了访问iframe中的元素，您必须切换到该iframe，如下所示：

from selenium import webdriver
from selenium.webdriver.chrome.options import Options
from selenium.webdriver.common.keys import Keys
import time
from datetime import datetime
from random import randint
import random
import string
import os
def get(link):
CHROMEDRIVER_PATH = 'chromedriver.exe'
options = webdriver.ChromeOptions()
options.add_argument("user-data-dir=E:\profile")
options.add_argument("--disable-notifications")
#options.add_argument("--headless")
options.add_experimental_option('excludeSwitches', ['enable-logging'])
driver = webdriver.Chrome(executable_path=CHROMEDRIVER_PATH,options=options)
driver.get(link)
time.sleep(2)
iframe = driver.find_element_by_xpath("//iframe[@class='embed-responsive-item']")
driver.switch_to.frame(iframe)
url_video = driver.find_element_by_xpath("/html/body/div/div[2]/div[3]/video").get_attribute('src')
print(url_video)
return url_video

link = "https://www.ofw.su/family-feud-july-29-2022"
get(link)

当您完成对iframe内元素的处理时，为了切换到常规内容，您应该使用以下代码：

driver.switch_to.default_content()

此外，您应该使用显式等待而不是硬编码延迟time.sleep(2)，并使用相对定位器，而不是像/html/body/div/div[2]/div[3]/video这样的绝对XPaths
