从 Yahoo Finance 下载多个代码数据

Question

我看到了 Andrej Kesely 在 StackOverflow 上发布的这段代码。我真的觉得它很有帮助，但我正在尝试下载多个代码而不是一个代码。 Cannot scrape from table in yahoo finance

目前，我正在下载多个价格代码，并且我使用 ['AAPL', 'MSFT', 'AMZN']，所以我尝试更改

url = ["https://finance.yahoo.com/quote/AAPL/key-statistics?p=AAPL","https://finance.yahoo.com/quote/AAPL/key-statistics?p =MSFT"]

它不起作用，我想知道是否有人知道如何将其更改为 url。非常感谢。

import requests
from bs4 import BeautifulSoup


url = "https://finance.yahoo.com/quote/AAPL/key-statistics?p=AAPL"

headers = {
    "User-Agent": "Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:89.0) Gecko/20100101 Firefox/89.0"
}

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

for t in soup.select("table"):
    for tr in t.select("tr:has(td)"):
        for sup in tr.select("sup"):
            sup.extract()
        tds = [td.get_text(strip=True) for td in tr.select("td")]
        if len(tds) == 2:
            print("{:<50} {}".format(*tds))

Answer 1

为什么不使用DataReader？

from pandas_datareader.data import DataReader # conda install pandas-datareader
data = DataReader(['AAPL', 'AMZN', 'GOOG', 'MFST'], 'yahoo', start='2015-01-01', end='2021-08-30')
print(data)

结果：

Answer 2

你也可以试试 yfinace:

import yfinance as yf
etf = ['AXP','AAPL','BA','CAT','CSCO','CVX','XOM','GS','HD','IBM','INTC','JNJ','KO'] #and any tickers you'd add to be retrived
tit = yf.download(tickers=etf, period='max')

Answer 3

您应该寻找：

• https://finance.yahoo.com/quote/MSFT/key-statistics?p=MSFT
• https://finance.yahoo.com/quote/AMZN/key-statistics?p=AMZN
• https://finance.yahoo.com/quote/APPL/key-statistics?p=APPL

在这种情况下，您可以使用 f-string：

tickers = ['AAPL', 'MSFT', 'AMZN']
for tick in tickers:
    print(f"https://finance.yahoo.com/quote/{tick}/key-statistics?p={tick}")
