Beautifulsoup刮擦多页

Question

我正试图弄清楚如何遍历多个页面来获得确实的公司评级。有任何想法吗？？？这是我完成的工作，以提取一页数据。

def parse(base_url):
base_url = requests.get('https://www.indeed.com/cmp/Google/reviews', timeout=5)
page_content = BeautifulSoup(base_url.content, 'lxml')
containers = page_content.findAll('div', {'class':'cmp-review-container'})
df = pd.DataFrame(columns = ['rating', 'rating_title', 'rating_description',
                     'rating_pros', 'rating_cons'])
for item in containers:
    try:
        rating = item.find('div', {'class': 'cmp-ratingNumber'}).text.replace('\n', '')
    except:
        rating = None
    try:
        rating_title = item.find('div', {'class': 'cmp-review-title'}).text.replace('\n', '')
    except:
        rating_title = None
    try:
        rating_description = item.find('span', {'class': 'cmp-review-text'}).text.replace('\n', '')
    except:
        rating_description = None
    try:
        rating_pros = item.find('div', {'class': 'cmp-review-pro-text'}).text.replace('\n', '')
    except:
        rating_pros = None
    try:
        rating_cons = item.find('div', {'class': 'cmp-review-con-text'}).text.replace('\n', '')
    except:
        rating_cons = None
    df = df.append({'rating': rating, 'rating_title': rating_title, 'rating_description': rating_description,
                         'rating_pros': rating_pros, 'rating_cons': rating_cons}, ignore_index=True)
return df
