尝试使用Except将无法使用TimeoutException

Question

我正在尝试查看是否在YouTube视频上启用了评论部分。如果不是，程序应该再次返回顶部。

def bot1():
    while True:

        #  First search
        driver.get("https://www.youtube.com/results?sp=CAISAggBUBQ%253D&q=" + k1)
        driver.find_element_by_class_name("yt-uix-tile-link").click()
        try:
            WebDriverWait(driver, 15).until(
                EC.presence_of_element_located((By.CLASS_NAME, "comment-simplebox-renderer-collapsed-content"))
            )
        except TimeoutException:
            bot1()

这给了我错误

Traceback (most recent call last):
  File "C:/Users/Admin/Desktop/My Programs/YouTubeTest/YouTubeTest.py", line 98, in <module>
    bot1()
  File "C:/Users/Admin/Desktop/My Programs/YouTubeTest/YouTubeTest.py", line 73, in bot1
    EC.presence_of_element_located((By.CLASS_NAME, "comment-simplebox-renderer-collapsed-content"))
  File "C:\Users\Admin\AppData\Local\Programs\Python\Python35-32\lib\site-packages\selenium\webdriver\support\wait.py", line 80, in until
    raise TimeoutException(message, screen, stacktrace)
selenium.common.exceptions.TimeoutException: Message: 

我有这个

from selenium.common.exceptions import TimeoutException

我完全不知道为什么会这样。
