I wrote the code below and it is running. When the loop run a fourth time, it gives an error. It gives "IndexError: list index out of range". How do I fix this error?

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)

推荐答案

• 对于8个股票代码，如果只有1个持有者，则 yfinance.ticker.Ticker 对象 stk_container.info 会导致错误.这是一个错误.
• yfinance:索引超出范围:一些代码#208
• 使用 try-except 块捕获异常.
  • Python:错误和异常
  • For 8 of the tickers, the yfinance.ticker.Ticker object, stk_container.info results in an error when there is only 1 holder. This is a bug.
  • yfinance: Index out of range: some Tickers #208
  • Use a try-except block to catch the exception.

    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)
        try:
            stk_info = stk_container.info
            print(stk_info)  # print the info
        except IndexError as e:
            print(f'{ticker}: {e}')  # print the ticker and the error
        print('\n')
