使用python ps4从网页中删除所有表

我想使用beautifulsoup获取此链接中的所有表

https://www.investing.com/indices/indices-futures

，接下来我想获取索引列中的标题以及这些标题的链接

我只想要第一栏的内容

比如说

title        href
Dow Jones    /indices/us-30-futures
S&P 500      /indices/us-spx-500-futures
...
Mini DAX     /indices/mini-dax-futures
...
VSTOXX Mini  /indices/vstoxx-mini 

我使用以下代码

url = "https://www.investing.com/indices/indices-futures"
req = requests.get(url, headers=urlheader)
soup = BeautifulSoup(req.content, "lxml")
table = soup.find('div', id="cross_rates_container")
for a in table.find_all('a', href=True):
    print (a['title'], a['href'])

我可以看到table变量，但似乎无法访问title（包含索引名）和href（包含链接）

有什么问题吗？如何一次获取所有表的条目

您可以迭代

元素并获得

这部分的意思
（'td.plusIconTd>a'）：
？@anarchy
汤。选择（'td.plusIconTd>a'）
选择
标记下带有
class=plusIconTd
的所有
元素<代码>'td.plusIconTd>a'

这是CSS选择器。<代码>{：你是怎么找到plusIconTd的？我看到的只是这个，我似乎找不到plusIconTd的一部分。谢谢你，我看到了，但是你怎么知道当名字是<代码>粗体左plusIconTd noWrap elp时只使用

plusIconTd

，

import requests
from bs4 import BeautifulSoup


url = 'https://www.investing.com/indices/indices-futures'
headers = {'User-Agent': 'Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:76.0) Gecko/20100101 Firefox/76.0'}
soup = BeautifulSoup(requests.get(url, headers=headers).content, 'html.parser')

print('{:<30} {}'.format('Title', 'URL'))
for a in soup.select('td.plusIconTd > a'):
    print('{:<30} {}'.format(a.text, 'https://www.investing.com' + a['href']))
