我正在使用代码来网络抓取客户评论。一切都按照我希望代码执行的操作进行，但我无法正确获取评级的类或属性，因此代码始终返回该Ratings列的空白结果。有人可以帮我找到正确的属性并修复Ratings代码行吗？from bs4 import BeautifulSoupimport requestsimport pandas as pdimport jsonprint ('all imported successfuly')# Initialize an empty dataframedf = pd.DataFrame()for x in range(1, 37):    names = []    headers = []    bodies = []    ratings = []    published = []    updated = []    reported = []    link = (f'https://www.trustpilot.com/review/fabfitfun.com?page={x}')    print (link)    req = requests.get(link)    content = req.content    soup = BeautifulSoup(content, "lxml")    articles = soup.find_all('article', {'class':'review'})    for article in articles:        names.append(article.find('div', attrs={'class': 'consumer-information__name'}).text.strip())        headers.append(article.find('h2', attrs={'class':'review-content__title'}).text.strip())        try:            bodies.append(article.find('p', attrs={'class':'review-content__text'}).text.strip())        except:            bodies.append('')        try:            #ratings.append(article.find('div', attrs={'class':'star-rating star-rating--medium'}).text.strip())            ratings.append(article.find('div', attrs={'class': 'star-rating star-rating--medium'})['alt'])        except:            ratings.append('')        dateElements = article.find('div', attrs={'class':'review-content-header__dates'}).text.strip()        jsonData = json.loads(dateElements)        published.append(jsonData['publishedDate'])        updated.append(jsonData['updatedDate'])        reported.append(jsonData['reportedDate'])
