如何仅打印网站中的特定href

Question

我正在尝试制作自动加入抽奖的网络抓取机器人。我有一个问题，只列出一个href，因为在URL中有2个。

其中一个页面指向我可以加入抽奖活动的页面，而另一个页面则指向创建抽奖活动的人的个人资料页面。

代码：

URL = 'https://scrape.tf/raffles/ending'
pagee = requests.get(URL)
Soup = BeautifulSoup(pagee.content, 'html.parser')
for link in Soup.select('a'):
    print(link.get('href'))

使用上面的代码，它打印个人资料页面和抽奖页面的href。我想做的是让代码只将href打印到抽奖页面。

配置文件页面和抽奖页面的href是不同的：

profile page = /profile/(raffle creator's username)
raffle page = /raffles/######

我尝试使用filter()函数，但它显示：

TypeError: filtfunc() takes 0 positional arguments but 1 was given

当我在filter()函数中使用其他代码时，它显示：

<filter object at ...........>

有没有办法让Python只打印抽奖的href？

Answer 1

您可以使用re模块和soup.find_all()

import re
import requests
from bs4 import BeautifulSoup


url = 'https://scrap.tf/raffles/ending'
soup = BeautifulSoup(requests.get(url).content, 'html.parser')

for raffle_link in soup.find_all(href=re.compile(r'/raffles/[A-Z\d]{6}')):
    print('{:<40} {}'.format('https://scrap.tf' + raffle_link['href'], raffle_link.text))

打印：
