如何使用python下載csv文件到目錄

Question

我想從雅虎查詢下載AAPL的歷史股票價格，但失敗。我對python非常陌生，不知道應用哪種方法將指定的鏈接自動提取到我所需的本地目錄中。

pullData（ 「AAPL」）的結果是： AAPL https://query1.finance.yahoo.com/v7/finance/download/AAPL?period1=345398400&period2=1505577600&interval=1d&events=history&crumb=X44gAJPyoNu 主迴路HTTP錯誤401：未經授權

import urllib2 
import time 
import csv 
import requests 
import pandas as pd 

def pullData(stock): 
    try: 
     print stock 
     url = 'https://query1.finance.yahoo.com/v7/finance/download/'+stock+'?period1=345398400&period2=1505577600&interval=1d&events=history&crumb=X44gAJPyoNu' 
     print url 

     response = urllib2.urlopen(url) 
     html = response.read() 


    except Exception,e: 
     print 'main loop',str(e)

你應該這樣解決 更新大熊貓的DataReader https://github.com/pydata/pandas-datareader/issues/315

import pandas as pd 
from pandas_datareader import data as web 

start = datetime.datetime(2015, 7, 1) 
end = datetime.datetime(2016, 7, 1) 
data - web.DataReader('AAPL', 'yahoo',start, end)
