问题
I am learning and using the pandas and python.
Today, I am trying to make a fx rate table, but I got a trouble with getting the pricess of 'USDJPY'.
When I get a prices of 'EUR/USD', i code like this.
eur = web.DataReader('EURUSD=X','yahoo')['Adj Close']
it works.
But when I wrote
jpy = web.DataReader('USDJPY=X','yahoo')['Adj Close']
the error message comes like this:
--------------------------------------------------------------------------- IOError Traceback (most recent call last) in () ----> 1 jpy = web.DataReader('USDJPY=X','yahoo')['Adj Close']

Other currencies like 'GBPUSD' also have same problem.
Can you solve this problem?
Do you have any idea of getting 'USDJPY' from yahoo or google???
回答1:
Yahoo Finance doesn't provide historical data on exchange rates (i.e. there's no "Historical Prices" link in the top left of the page like there would be for stocks, indices, etc...)
You can use FRED (Federal Reserve of St. Louis data) to get these exchange rates...
import pandas.io.data as web
jpy = web.DataReader('DEXJPUS', 'fred')
or the more direct way...
jpy = web.get_data_fred('DEXJPUS')
A list of all of the exchange rate that FRED has daily data for can be found here: http://research.stlouisfed.org/fred2/categories/94

Yes it does but not on cross rates. All vs the USD List of Yahoo USD Exchange Rates
a = web.DataReader("JPY=X", 'yahoo')

Get the historical exchange rates from OANDA http://pandas-datareader.readthedocs.io/en/latest/remote_data.html
In [1]: from pandas_datareader.oanda import get_oanda_currency_historical_rates
In [2]: start, end = "2016-01-01", "2016-06-01"
In [3]: quote_currency = "USD"
In [4]: base_currency = ["EUR", "GBP", "JPY"]
In [5]: df_rates = get_oanda_currency_historical_rates(
start, end,
quote_currency=quote_currency,
base_currency=base_currency
)
In [6]: print(df_rates)
Update: Oanda started charging for this lately https://www.oanda.com/fx-for-business/exchange-rates-api
