Answer 1

要获得“SIC”行的值，可以使用以下示例(还需要指定正确的User-Agent )：

import requests
from bs4 import BeautifulSoup


url = 'https://sec.report/CIK/1418076'
headers = {'User-Agent': 'Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:78.0) Gecko/20100101 Firefox/78.0'}

soup = BeautifulSoup(requests.get(url, headers=headers).content, 'html.parser')

print( soup.find('td', text="SIC").find_next('td').text )

指纹：

7129: Other Business Financing Companies Investors, Not Elsewhere Classified 6799

编辑:将解析器更改为lxml，以正确解析HTML：

import requests
from bs4 import BeautifulSoup

url = 'https://sec.report/CIK/1002771'
headers = {'User-Agent': 'Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:78.0) Gecko/20100101 Firefox/78.0'}

soup = BeautifulSoup(requests.get(url, headers=headers).content, 'lxml')

print( soup.find('td', text="SIC").find_next('td').text )

指纹：

Answer 2

试试下面的代码：

import requests
from bs4 import BeautifulSoup
headers = {'User-Agent': 'Mozilla/5.0 '}
r = requests.get('https://sec.report/CIK/1418076', headers=headers)

soup = BeautifulSoup(r.content, 'lxml')

sic = soup.select_one('.table:nth-child(5) tr~ tr+ tr td:nth-child(2)')
print(sic.text)

输出：

7129: Other Business Financing Companies Investors, Not Elsewhere Classified 6799
