python - 抓取 href 链接

Question

尝试使用正确的关键字收集此页面上的特定链接，到目前为止我有:

from bs4 import BeautifulSoup
import random
url = 'http://www.thenextdoor.fr/en/4_adidas-originals'
r = requests.get(url)
soup = BeautifulSoup(r.text, 'lxml')
raw = soup.findAll('a', {'class':'add_to_compare'})
links = raw['href']
keyword1 = 'adidas'
keyword2 = 'thenextdoor'
keyword3 = 'uncaged'
for link in links:
    text = link.text
    if keyword1 in text and keyword2 in text and keyword3 in text:

我正在尝试提取 this link

Answer 1

您可以使用 all() 检查是否所有都存在，以及是否存在 any()

from bs4 import BeautifulSoup
import requests

res = requests.get("http://www.thenextdoor.fr/en/4_adidas-originals").content
soup = BeautifulSoup(res)

atags = soup.find_all('a', {'class':'add_to_compare'})
links = [atag['href'] for atag in atags]
keywords = ['adidas', 'thenextdoor', 'Uncaged']

for link in links:  
    if all(keyword in link for keyword in keywords):
        print link

输出:
