Yahoo Finance Python API JSON 오류?

Question

저는 역사적인 가격을 얻기 위해 Yahoo Finance Python API를 사용하려고했지만 코드를 실행하려고 할 때마다 동일한 오류가 발생합니다. 그것이 내가 Jupyter 노트북 및 파이썬 3

를 사용하고, 도움이된다면

파이썬 코드

from yahoo_finance import Share 

name = Share('YHOO') 
temp = (name.get_historical('2014-04-25','2015-04-29')) 

print (temp) 

그리고 오류 메시지

는 여기 https://pypi.python.org/pypi/yahoo-finance

그것은 말한다로부터의 지시를 따랐습니다 :

Yahoo! Finance backend is http://datatables.org/ . If this service is down or has network problems you will receive errors from group YQL*, eg. YQLQueryError.

그래서이 서비스는 밖으로 그리고 당신은 YQL 오류가 계속 이유입니다. 나는이 문제가 2016 년으로 거슬러 올라간다면 서비스가 잠시 중단 된 것으로 가정하고 있습니다.

YQL (Yahoo Query Language)을 사용해 볼 수 있습니다. 여기에 시작하기위한 페이지가 있습니다 https://developer.yahoo.com/yql/#python
