Python 中某些股票代码的盈利日期

Question

我想获取 S&P500 股票行情报告的发布日期列表。我正在使用 Python 语言中的 yfinance 和 Streamlit 模块并收到此错误消息：

“获取 WMB 收入数据时出错：尚未实现从 Yahoo API 获取“收入””。

当前代码：

import streamlit as st
import pandas as pd
import yfinance as yf
from datetime import datetime, timedelta
import requests
from io import StringIO

# Function to fetch earnings report dates for a given ticker
def get_earnings_dates(ticker):
    try:
        stock = yf.Ticker(ticker)
        earnings = stock.earnings
        return earnings
    except Exception as e:
        print(f"Error fetching earnings data for {ticker}: {e}")
        return None

# Function to generate earnings report dates for S&P 500 tickers in the past year
def generate_earnings_reports():
    try:
        # Fetch S&P 500 tickers
        url = "https://raw.githubusercontent.com/datasets/s-and-p-500-companies/master/data/constituents.csv"
        data = requests.get(url).content.decode('utf-8')
        sp500_tickers = pd.read_csv(StringIO(data))['Symbol'].tolist()
        
        print(f"Found {len(sp500_tickers)} S&P 500 tickers.")
        
        earnings_data = {}
        for ticker in sp500_tickers:
            print(f"Fetching earnings data for {ticker}...")
            earnings = get_earnings_dates(ticker)
            if earnings is not None and not earnings.empty:
                earnings_data[ticker] = earnings['Earnings Date'].tolist()
        return earnings_data
    except Exception as e:
        print(f"Error generating earnings report dates: {e}")
        return None

# Streamlit app
def main():
    st.title('S&P 500 Earnings Report Dates')

    earnings_data = generate_earnings_reports()

    if earnings_data:
        st.write("Earnings Report Dates for S&P 500 Stocks in the Past Year:")
        for ticker, dates in earnings_data.items():
            st.write(f"Ticker: {ticker}")
            st.write("Earnings Report Dates:")
            for date in dates:
                st.write(date.strftime('%Y-%m-%d'))
            st.write("---")
    else:
        st.write("Failed to fetch earnings report dates for S&P 500 tickers in the past year.")

if __name__ == "__main__":
    main()

我正在使用 stock.earnings_dates 从 yfinance 库调用收益。然而，我认为图书馆今天在提取收益日期方面存在问题。我从输出中收到 KeyError: 'Earnings Date'。
