<a class="yt-simple-endpoint style-scope yt-formatted-string" spellcheck="false" href="/redirect?redir_token=ix1uBK3TO3bxXdcT7EvDFp-vI9p8MTU0NjQxNTExOEAxNTQ2MzI4NzE4&amp;event=comments&amp;q=https%3A%2F%2Fjulissars.itworks.com%2F&amp;stzid=Ugw6ip_QkzwyJPIq3bp4AaABAg" rel="nofollow">https://julissars.itworks.com&#65279;</a>

代码试用（没有用户代理，它工作）：

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

driver = webdriver.Firefox()
driver.get("https://www.youtube.com/watch?v=UJezMYvf8Ss&lc=Ugw6ip_QkzwyJPIq3bp4AaABAg")
WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//a[@class='yt-simple-endpoint style-scope yt-formatted-string' and contains(., 'julissars')]"))).click()

代码试用（使用用户代理，不起作用）：

from selenium import webdriver
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.chrome.options import Options
from fake_useragent import UserAgent

useragent = UserAgent()
profile = webdriver.FirefoxProfile()
profile.set_preference("general.useragent.override", useragent.random)
driver = webdriver.Firefox(firefox_profile=profile)
driver.get("https://www.youtube.com/watch?v=UJezMYvf8Ss&lc=Ugw6ip_QkzwyJPIq3bp4AaABAg")
WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//a[@class='yt-simple-endpoint style-scope yt-formatted-string' and contains(., 'julissars')]"))).click()

要在url中单击所需的注释，文本为https://julissars.itworks.com，您需要引导WebDriverwait以使元素可单击，您可以通过Selenium和Python使用useragent使用以下解决方案：

代码块：

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

ua = UserAgent()
options = webdriver.ChromeOptions()
userAgent = ua.random
print(userAgent)
options.add_argument('user-agent=' + userAgent)
driver = webdriver.Chrome(chrome_options=options, executable_path=r'C:\Utility\BrowserDrivers\chromedriver.exe')
driver.get("https://www.youtube.com/watch?v=UJezMYvf8Ss&lc=Ugw6ip_QkzwyJPIq3bp4AaABAg")
WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//a[@class='yt-uix-sessionlink  ' and contains(@href, 'julissars')]"))).click()
