Answer 1

Rujuk kod berikut:

#!/usr/bin/env python
# -*- coding:utf-8 -*-

import re
import requests
from bs4 import BeautifulSoup

result = requests.get('https://movie.douban.com/subject/3541415/')
result.encoding = 'utf-8'
soup = BeautifulSoup(result.text, 'html.parser')

try:
    info = soup.select('#info')[0]
    print re.findall(ur'(?<=制片国家/地区: ).+?(?=\n)', info.text)[0]
except Exception, e:
    print e

soup.find_all("title")
# [<title>The Dormouse's story</title>]

soup.find_all("p", "title")

soup.find_all("a")
# [<a class="sister" href="http://example.com/elsie" id="link1">Elsie</a>,
