简单的网页刮板格式，我如何解决这个问题？

Question

我有这个密码：

import requests
from bs4 import BeautifulSoup



def posts_spider():
    url = 'http://www.reddit.com/r/nosleep/new/'
    source_code = requests.get(url)
    plain_text = source_code.text
    soup = BeautifulSoup(plain_text)
    for link in soup.findAll('a', {'class': 'title'}):
        href = "http://www.reddit.com" + link.get('href')
        title = link.string
        print(title)
        print(href)
        print("\n")

def get_single_item_data():
    item_url = 'http://www.reddit.com/r/nosleep/new/'
    source_code = requests.get(item_url)
    plain_text = source_code.text
    soup = BeautifulSoup(plain_text)
    for rating in soup.findAll('div', {'class': 'score unvoted'}):
        print(rating.string)

posts_spider()
get_single_item_data()

输出为：

我想做的是，将每个帖子的匹配评分放在它旁边，这样我就可以立即知道该帖子有多少评分，而不是在一个“块”中打印标题和链接，在另一个“块”中打印评分数字。 提前感谢您的帮助！你知道吗

Answer 1

您可以通过使用class="thing"迭代div元素一次完成（可以将其视为对post的迭代）。对于每个div，获取链接和评级：

from urlparse import urljoin

from bs4 import BeautifulSoup
import requests

def posts_spider():
    url = 'http://www.reddit.com/r/nosleep/new/'
    soup = BeautifulSoup(requests.get(url).content)
    for thing in soup.select('div.thing'):
        link = thing.find('a', {'class': 'title'})
        rating = thing.find('div', {'class': 'score'})
        href = urljoin("http://www.reddit.com", link.get('href'))

        print(link.string, href, rating.string)

posts_spider()

仅供参考，div.thing是一个^{}，它将所有div与class="thing"匹配。你知道吗
