Question

有人知道如何将yahoo finance csv直接导入python吗？

问题在于，当我尝试使用此（示例）链接获取数据时：

http://real-chart.finance.yahoo.com/table.csv?s=WU&a=4&b=20&c=2015&d=05&e=21&f=2016&g=d&ignore=.csv'

它会弹出一个询问我是否要下载csv文件的弹出窗口。当我尝试将其读入python时，这会导致它崩溃。我的脚本是：

today = datetime.date.today()

def get_url(stock='GOOG', START_date = str(int(str(today).split('-')[0])-1)+
            '-' +str(int(str(today).split('-')[1])-1) + ('-') +
            str(int(str(today).split('-')[2])-1), END_date= str(today)):
    baseurl = 'http://real-chart.finance.yahoo.com/table.csv?'
    stock = 's=WU'

    FROM_date = ('&a=' + START_date.split('-')[1] + '&b=' +
    START_date.split('-')[2] + '&c=' +
    START_date.split('-')[0])

    TO_date = ('&d=' + END_date.split('-')[1] + '&e=' +
    END_date.split('-')[2] + '&f=' + END_date.split('-')[0])

    url = baseurl + stock + FROM_date + TO_date + '&g=d&ignore=.csv'
    return url

rawdate = []
with open(get_url()) as csvfile:
    reader = csv.reader(csvfile, delimiter = ",")
    for row in reader:
        rawdata.append(row)

如果我首先下载csv我可以将其读入python，但我想直接访问csv文件而不必先下载它。这可能吗？或者将csv作为临时值。

谢谢！

我建议您使用熊猫。这是link。

import pandas.io.data as web
import datetime
start = datetime.datetime(2010, 1, 1)
end = datetime.datetime(2013, 1, 27)
f = web.DataReader("F", 'yahoo', start, end)
f.ix['2010-01-04']

以这种方式试试。

in this file "C:/Users/your_path/Desktop/symbols/tickers.txt"
you have the following tickers
ibm
sbux
msft
"""

import urllib
import re
import json

symbolslist = open("C:/Users/rshuell001/Desktop/symbols/tickers.txt").read()
symbolslist = symbolslist.split("\n")

for symbol in symbolslist:
    myfile = open("C:/Users/rshuell001/Desktop/symbols/" +symbol +".txt", "w+")
    myfile.close()

    htmltext = urllib.urlopen("http://www.bloomberg.com/markets/chart/data/1D/"+ symbol+ ":US")
    data = json.load(htmltext)
    datapoints = data["data_values"]

    myfile = open("C:/Users/rshuell001/Desktop/symbols/" +symbol +".txt", "a")
    for point in datapoints:
        myfile.write(str(symbol+","+str(point[0])+","+str(point[1])+"\n"))
    myfile.close()

那可以给你你想要的东西。
