我正在尝试抓取https://www.betexplorer.com/soccer/england/premier-league/fixtures/来提取'a'标记中包含的文本，特别是在带有“ table-main”类的表中，然后针对其中的每一行。第一个td包含带有两个团队名称的文本，其td类为“ h-text-left”。不确定问题是否出在我的循环中，但是我收到的错误消息似乎是我在循环的最后一行中错误地使用了bs4。
我可以使用“ table-main”类刮擦表中的每个tr，然后使用“ h-text-left”类刮擦每个td。但是，当我尝试仅提取“ a”元素而不是“ a”文本时，我遇到了麻烦。
import requests
from bs4 import BeautifulSoup
headers = {'User-Agent':
'Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/47.0.2526.106 Safari/537.36'}
r = requests.get('https://www.betexplorer.com/soccer/england/premier-league/fixtures/', headers=headers)
c = r.content
soup = BeautifulSoup(c)
fixture_table = soup.find('table', attrs = {'class': 'table-main'})
for tr in soup.find_all('tr'):
match_tds = tr.find_all('td', attrs = {'class': 'h-text-left'})
matches = match_tds.find_all('a')
当我尝试查找所有'a'标签时，最后一行会跳出以下错误：
... matches = match_tds.find_all('a')
...
Traceback (most recent call last):

您可以使用单个类将其缩减为更快的选择器方法。所有链接具有相同的类名，因此您可以select在列表推导中将其传递给，以为您提供所有链接。
