【问题描述】：

我曾尝试从雅虎财经下载市场数据，但一直出错。这是我的代码：

import yfinance as yf

#import data of different asset classes
VT = yf.download("VT",interval="1d", start="2017-01-01", end="2021-01-01") #stocks
BND = yf.download("BND",interval="1d", start="2017-01-01", end="2021-01-01") #bonds
VNQ = yf.download("VNG",interval="1d", start="2017-01-01", end="2021-01-01") #real estate
DBC = yf.download("DBC",interval="1d", start="2017-01-01", end="2021-01-01") #commodities

出现此错误：

KeyboardInterrupt                         Traceback (most recent call last)

      4 VNQ = yf.download("VNG",interval="1d", start="2017-01-01", end="2021-01-01") #real estate
      5 DBC = yf.download("DBC",interval="1d", start="2017-01-01", end="2021-01-01") #commodities

【问题讨论】：

当前版本好像有各种问题。在我的环境中，使用最新版本（0.62.1），没有错误。

请问有没有其他下载市场数据的方式可能比雅虎财经更好？

我敢肯定还有像yahoo_fin、yahooquery、pandas-datareader这样的人，但我个人推荐yfinance。

【参考方案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")
