import requests
from bs4 import BeautifulSoup

re  = requests.get("https://www.rtvs.sk/embed/audio/242500")
soup = BeautifulSoup(re.text, 'html.parser')

result = soup.findAll("div", id="player_audio_242500")
print(result)

for n in soup.findAll("div", id="player_audio_242500"):
    if 'src' in n.attrs:
        result = n['src']
    else:
        result = n.text
    print(result)

for n in soup.find_all('script'):
    print(n.get('src'))

for n in soup.find_all('script'):
    if 'src' in n.attrs:
        result = n['src']

from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.chrome.service import Service

ser = Service("chromedriver")
op = webdriver.ChromeOptions()
chrome_browser = webdriver.Chrome(service=ser, options=op)
chrome_browser.maximize_window()
chrome_browser.get('https://www.rtvs.sk/embed/audio/242500')

enter = chrome_browser.find_element(by=By.CSS_SELECTOR, value="[id^=player_audio]")
print(enter)
print(enter.text)

有人可以帮忙吗？

看看你的 css selector，它应该 select video 并且应该采用它的 src 属性：

chrome_browser.find_element(By.CSS_SELECTOR, 'video').get_attribute("src")
