如何获得 Python 中的股票市场价格。可靠，每次都有效

Question

我希望将股票市场数据导入数据框。我试过 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。我已经尝试过 yahoo finance 和 web.DataReader 解决方案。这些结果发布在下面。

我也试过 Quandl，但它没有我要找的所有代码....

df_IJR = yf.download("IJR", start=start_data, end=end_data).reset_index()

df_IJR = yf.download("IJR", start=start_data, end=end_data).reset_index()
Exception in thread Thread-22:

这里是 web.DataReader 结果。

df_google = web.DataReader("GOOGL", 'yahoo', start_data, end_data)['Close'].reset_index()

Answer 1

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")

我还建议查看 financialmodelingprep，它们非常可靠并且有免费版本。
