我正試圖從紐約時報頭版 (www.nytimes.com) 上獲取頭條新聞。過程完成而不從soup.find_all函數(shù)打印文本（或任何東西）。我已經soup.find_all(class_="blancedHeadline")嘗試過語法，將其從soup.find_all("span", {"class" : "blancedHeadline")甚至attrs=在類區(qū)別之前添加。這是我擁有的代碼，在嘗試弄清楚我做錯了什么之后，我不知道是什么導致了問題：import requestsfrom bs4 import BeautifulSoupbase_url = 'https://www.nytimes.com/'r = requests.get(base_url)soup = BeautifulSoup(r.text, 'lxml')headline_text = soup.find_all('span', {'class':'balancedHeadline'})for headline in headline_text:    print(headline)
