使用 pandas yahoo finance datareader 下载多只股票并将它们放入 DataFrame

Question

大家好，我想使用 Pandas 从 yahoo finance 下载多只股票。
但与此同时，我需要 仅保存每只股票的“Adj Close”列。
此外，我想创建一个包含所有这些“Adj Close”列的DataFrame，并将列名称设置为股票代码。

我尝试使用此代码，但卡住了。

import numpy as np 
import pandas as pd 
from datetime import datetime
import pandas_datareader.data as web

stocks = ['ORCL', 'TSLA', 'IBM','YELP', 'MSFT']
ls_key = 'Adj Close'
start = datetime(2014,1,1)
end = datetime(2015,1,1)    
f = web.DataReader(stocks, 'yahoo',start,end)
f

希望有人能帮助我

df = f[[("Adj Close", s) for s in stocks]]
df.columns = df.columns.droplevel(level=0)
