python - 找不到 pandas.read_html 表

Question

我正尝试通过此 URL 在 Yahoo Finance 中获取主要世界指数的列表:https://finance.yahoo.com/world-indices .我首先尝试通过运行来获取表中的索引

major_indices=pd.read_html("https://finance.yahoo.com/world-indices")[0]

在这种情况下，错误是:

ValueError: No tables found

So I read a solution using selenium at pandas read_html - no tables foundthe solution they came up with is (with some adjustment):

from selenium import webdriver
import pandas as pd
from selenium.webdriver.common.keys import Keys
from webdrivermanager.chrome import ChromeDriverManager


driver = webdriver.Chrome(ChromeDriverManager().download_and_install())
driver.get("https://finance.yahoo.com/world-indices")

html = driver.page_source

tables = pd.read_html(html)
data = tables[1]

此代码再次给了我另一个错误:

ValueError: No tables found

我不知道是继续使用 selenium 还是 pd.read_html 就好了。无论哪种方式，我都在尝试获取这些数据，但不知道如何进行。谁能帮帮我？

Answer 1

这里不需要Selenium，你只需要设置euConsentId cookie:

import pandas as pd
import requests
import uuid

url = 'https://finance.yahoo.com/world-indices'
cookies = {'euConsentId': str(uuid.uuid4())}

html = requests.get(url, cookies=cookies).content
df = pd.read_html(html)[0]

输出:
