Question

我正在尝试从下面的页面获取信息

http://books.toscrape.com/

我想获得每本书的评分（星级），我使用了下面的代码

import requests
from bs4 import BeautifulSoup
from urllib.request import urlopen
import re

response = requests.get(
    'http://books.toscrape.com/')
if response.status_code == 200:
    print('Requisição bem sucedida!')

linhas = soup.find_all(class_=re.compile("rating"))

但接下来是

<p class="star-rating Three">
<i class="icon-star"></i>
<i class="icon-star"></i>
<i class="icon-star"></i>
<i class="icon-star"></i>
<i class="icon-star"></i>
</p>,

我做错了什么？

Answer 1

实际上，class-name 包含了星级值，因此我们可以使用 attrs['class'] 方法或 d['class'][1] 进行提取！

import requests
from bs4 import BeautifulSoup
from urllib.request import urlopen
import re

response = requests.get(
    'http://books.toscrape.com/')

soup=BeautifulSoup(response.text,"html.parser")

data=soup.find_all("p",class_="star-rating")
for d in data:
    print(d.attrs['class'][1])

输出：

Three
One
One
Four
..
