Python Finance：get_data_yahoo 未检索数据

Question

大约一年前我运行了这段代码，它运行良好。 现在它已经停止工作，我认为它与 get_data_yahoo 函数有关。 这是我尝试运行的部分代码：

pd.options.display.width = 0

stocklist = si.tickers_sp500()
index_name = '^GSPC'  # S&P 500: ^GSPC  Dow Jones: ^DJI   Nasdaq: ^IXIC

# Initiate stock index
n = -1

for stock in stocklist:
    n += 1

    # Set a time delay between each stock
    time.sleep(0.25)

    # Inform user which stock is being evaluated
    print("\nPulling {} with Index {}".format(stock, n))

    # Set 1-year time duration starting from 365 days ago today
    start_date = datetime.datetime.now() - datetime.timedelta(days=365)
    end_date = datetime.date.today()

    # Download stock data for set time duration
    # (Optional??) stock = [stock + '.AX' for stock in stocklist]
    df = pdr.get_data_yahoo(stock, start=start_date, end=end_date)

现在这不返回任何数据。 我错过了什么？

可能库的语法已经改变。 我更改了您的代码并尝试请求几个 10 股。 40岁以后，我自己停止了。 在我看来，没有必要经常滥用和请求数据，而不是太多。 并且还将请求的深度减少了四天。 如果您请求深度数据，很有可能您会遇到未交易的股票并且脚本将关闭（我见过这样的问题）。

import pandas_datareader.data as web
import yahoo_fin.stock_info as si
import pandas as pd
import datetime
import time

pd.options.display.width = 0

stocklist = si.tickers_sp500()
index_name = '^GSPC'  # S&P 500: ^GSPC  Dow Jones: ^DJI   Nasdaq: ^IXIC
n = -1

for stock in stocklist:
    n += 1

    # Set a time delay between each stock
    time.sleep(0.25)

    # Inform user which stock is being evaluated
    print("\nPulling {} with Index {}".format(stock, n))

    # Set 1-year time duration starting from 365 days ago today
    start_date = datetime.datetime.now() - datetime.timedelta(days=4)
    end_date = datetime.date.today()

    df = web.DataReader(stock, 'yahoo', start=start_date, end=end_date)
    print(df)
