问题描述
我希望将股票市场数据导入数据框。我尝试过 web.DataReader 和 Yahoo Finance，结果如下。 我在网上寻找从互联网获取股票数据的“可重复”解决方案。 我尝试过雅虎金融和 web.DataReader 解决方案。这些结果发布在下面。
我也尝试过 Quandl，但它没有我正在寻找的所有代码......
df_IJR = yf.download("IJR",start=start_data,end=end_data).reset_index()
df_IJR = yf.download("IJR",end=end_data).reset_index()

使用 web.DataReader，结果如下。
df_google = web.DataReader("GOOGL",'yahoo',start_data,end_data)['Close'].reset_index()

解决方法
试试这个：
import datetime as dt
import pandas as pd
import yfinance as yf
from pandas_datareader import data as pdr
tickers = ["AAPL","GOOG","AMZN"]
yf.download(tickers,start = "2021-02-01",end = "2021-02-04")
我还建议您查看 Financialmodelingprep，它们非常可靠并且有免费版本。
