一、在豆瓣電影網爬取影片的短評以及相關的信息：

二、參考代碼

            
              import requests
from bs4 import BeautifulSoup
import pandas as pd

url_list = []
for i in range(5):
    url_list.append('https://movie.douban.com/subject/26794435/comments?start=%s&limit=20&sort=new_score&status=P'%(i*20))

n = 0
commentInfo_list =[]
for url in url_list:
    txt = requests.get(url).text # 網頁的獲取
    soup = BeautifulSoup(txt,'lxml')  # 網頁的解析

    divs = soup.find('div',id='comments').find_all('div',class_='comment')        
    for div in divs:
        comments_dict ={}        
        comments_dict['用戶名'] = div.find('span',class_ = 'comment-info').find('a').text
        comments_dict['評論時間'] = div.find('span',class_= 'comment-time').text.replace(' ','').replace('\n','')
        comments_dict['有用數量'] = div.find('span',class_= 'votes').text
        comments_dict['評論內容'] = div.find('span',class_='short').text
        
        commentInfo_list.append(comments_dict)            
        n += 1        
print('已成功采集%s條評論'%n)    

df = pd.DataFrame(commentInfo_list)
