Fixing panda's datareader from yahoo finance with Enthought Canopy

问题

pandas' datareader from yahoo finance is not working at the moment because yahoo changed the url pandas used to get the data from, yahoo changed it from 'http://ichart.yahoo.com/table.csv?... to 'http://ichart.finance.yahoo.com/table.csv?....

The error I'm getting is IOError: after 3 tries, Yahoo! did not return a 200 for url '...'

So, I tried editing data.py, according to this fix, but still no go. I'm using pandas 0.12, with Enthought Canopy. Do I need to compile something..? is there anything more required?

回答1:

in (assuming that the user is using Enthought Canopy for Windows, and it's stored in the default location):

C:\Users\...\AppData\Local\Enthought\Canopy\System\Lib\site-packages\pandas\io

change yahoo_URL = 'http://ichart.yahoo.com/table.csv?'

to yahoo_URL = 'http://ichart.finance.yahoo.com/table.csv?'

Save and restart Canopy

Here is a current, working version of using Pandas datareader to fetch yahoo quotes:

from pandas.io.data import DataReader
from datetime import datetime

amd = DataReader('AMD',  'yahoo', datetime(2015,7,1), datetime(2015,7,1))
print(amd['Adj Close'][0])

Keep in mind that the returned dataset is an array. You need to enumerate said array to get the data, either by specifying your index, or with a for loop

The other keys you can use are Open, Close, High, Low, and Volume.

I have Pandas v 0.16.2

I hope this helps!
