Python ConnectionError：HTTPSConnectionPool（host ='finance.yahoo.com'，端口= 443）：读取超时

Question

我正在编写以下代码行

import numpy as np
import pandas as pd
from pandas_datareader import data as wb
tickers=['RELIANCE.NS','MBECL.NS']
mystocks=pd.DataFrame()
for t in tickers:
    mystocks[t]=wb.DataReader(t,data_source='yahoo',start='2015-1-1')['Adj Close']

mystocks

但这返回了
ConnectionError: HTTPSConnectionPool(host='finance.yahoo.com', port=443): Read timed out.

从浏览器访问Yahoo Finance。直到上周我才能够执行此操作，但是现在同一行代码抛出连接错误。

Answer 1

我建议您将获取数据帧的代码放在 try / except 语句中。这样它就会等到你的连接重新建立。

for t in tickers:
    try:
        mystocks[t]=wb.DataReader(t,data_source='yahoo',start='2015-1-1')['Adj Close']
    except:
        continue

mystocks
