我写了下面的代码，它正在运行。当循环第四次运行时，它给出了一个错误。它给出“IndexError：列表索引超出范围”。如何修复此错误？

import yfinance as yf

dow_list = ['AAPL', 'AXP', 'BA', 'CAT', 'CSCO', 'CVX', 'DIS', 'DOW', 'GS', 'HD', 'IBM', 'INTC', 'JNJ', 'JPM', 'KO', 'MCD', 'MMM', 'MRK', 'MSFT', 'NKE', 'PFE', 'PG', 'RTX', 'TRV', 'UNH', 'V', 'VZ', 'WBA', 'WMT', 'XOM']

rows = []

for ticker in dow_list:
    stk_container = yf.Ticker(ticker)
    stk_info = stk_container.info
    print(stk_info)

追溯
