标题: python使用beautifulsoup问题
  这里是代码
  1. import sys
  2. import urllib
  3. from urllib import request
  4. import os
  5. from bs4 import BeautifulSoup

  7. class DramaItem:
  8.     def __init__(self, num, title, url):
  9.         self.num = num
  10.         self.title = title
  11.         self.url = url
  12.     def __str__(self):
  13.         return self.num + '    ' + self.title
  14.     def openDrama(self):
  15.         os.startfile(self.url)
  16. response = urllib.request.urlopen('URL')
  17. html = response.read()
  18. soup = BeautifulSoup(html)
  19. dramaList = soup.findAll('div', attrs={'class':'list_block1 align_c'})
  20. dramaItems = []
  21. if(dramaList):
  22.     lis = dramaList[0].findAll('li')
  23.     for li in lis:
  24.         ps = li.findAll('p')
  25.         description = ps[1].text if len(ps)>1 else ''
  26.         num = ps[0].find('a').text
  27.         url = ps[0].find('a')['href']
  28.         di = DramaItem(num, description, url)
  29.         dramaItems.append(di)
  30. for di in dramaItems:
  31.     print(di)
  32. diLen = len(dramaItems)
  33. userChoice = int(input('input number to watch the drama:'))
  34. if userChoice >= 1 and userChoice <=diLen:
  35.     dramaItems[userChoice-1].openDrama()
复制代码
里面的dramaList = soup.findAll('div', attrs={'class':'list_block1 align_c'})中
attrs={'class':'list_block1 align_c'}这句怎么解释
