关于python爬虫IndexError: list index out of range的问题

​
def get_total_num_of_article(URL):
  source_code_from_url = urllib.request.urlopen(URL)
  soup = BeautifulSoup(source_code_from_url, 'lxml', from_encoding='utf-8')
  total_num_of_article = soup.select('span.total_number')
  num = total_num_of_article[0].string
  position = num.index('(') 
  num = num[position:]  
  num = re.sub('[^0-9]', '', str(num)) 
  num = int(num)
  if(num % 15 >= 1): 
    page_num = int((num / 15) + 1) 
  else: 
    page_num = int(num / 15) 
  return page_num

page_num = get_total_num_of_article(TARGET_URL)

请教一下为什么第6行 num = total_num_of_article[0].string这一行代码总是报错list index out of range啊

有没有大神帮忙解答55

是用colab写的，也试了查到的tryexcept方法好像还是不太行

是爬取韩网新闻的代码

total_num_of_article 的长度能可能为 0，你调用 total_num_of_article[0] 前先判断一下吧。
