我想从 yfinance 模块中获取历史收盘价，并创建一个数据框，其中有一列包含存储在 Holdings 列表中的每个代码的收盘价。除了最后创建该数据框外，我可以做任何事情。有人可以帮忙吗？：

Holdings = ['RL', 'AMC', 'BYND', 'BRK-B', 
            'BBY', 'AYX', 'AAPL', 'KO', 
            'FB', 'RACE', 'INTC', 'PFE', 
            'CRM', 'WFC', 'JPM', 'GOOG']

Hist_Holdings = []

for symbol in Holdings:
    Ticker = yf.Ticker(symbol)
    Hist = Ticker.history(period = "6mo", interval = "1d")
    
    Hist = Hist['Close']
    Hist.columns = [symbol]
    Hist_Holdings.append(Hist)

所需的数据框格式未知，但以下代码会将您想要获取的股票与空格连接起来。它速度很快，并以数据帧格式返回数据。下面的代码仅指定收盘价。

import yfinance as yf
import datetime

now_ = datetime.datetime.today()

start = datetime.datetime(now_.year, now_.month - 6, now_.day + 1)
end = datetime.datetime(now_.year, now_.month, now_.day - 1)

Holdings = 'RL AMC BYND BRK-B BBY AYX AAPL KO FB RACE INTC PFE CRM WFC JPM GOOG'
data = yf.download(Holdings, start=start, end=end)['Close']

AAPL    AMC     AYX     BBY     BRK-B   BYND    CRM     FB  GOOG    INTC    JPM     KO  PFE     RACE    RL  WFC
Date
