'DataFrame' 对象没有属性 'split' 从 .csv 文件导入股票代码列表时出现问题

Question

我在使用 yfinance 时遇到问题：我必须从 .csv 文件导入 101 个代码才能下载收盘价。

这是我的代码：

import pandas as pd
import yfinance as yf
import datetime

tickers = pd.read_csv('symbols.csv', sep=";", header=None, nrows=1)
stocks = yf.download(tickers, start="2020-03-31",end="2020-04-20")
close = stocks['Close']
print(close)

我的 .csv 文件只有一行，所有代码都用“;”分隔。我该如何修复它？谢谢！ :)

Answer 1

.download() 采用列表或字符串，但不采用 DataFrame。

我建议改为使用 csv 模块读取文件：

import csv 

with open('symbols.csv','r') as f:
    reader = csv.reader(f,delimiter=';')
    tickers = next(reader) # tickers is now a list

stocks = yf.download(tickers, start="2020-03-31",end="2020-04-20")

结果（使用 AAPL 和 GOOGL）：

In [19]: stocks
Out[19]: 
             Adj Close                    Close  ...         Open    Volume
