inflation_calc
inflation_calc provides a toolkit with economical computations based on data from data.okfn.org. This project builds heavily on the work of economics <https://pypi.python.org/pypi/economics>
Features
- CPI
- Inflation (based on CPI by default)
- predict (predicts future cpi's based on current cpi's using ARIMA)
Requirements
CPI
>> from inflation_calc.cpi import CPI >> import datetime >> >> # Create a new CPI instance >> cpi = CPI() >> >> # Get CPI for Iceland in 2007 >> cpi.get(datetime.date(2007,1,1), 'Iceland') CPI(date=datetime.date(2007, 1, 1), value=112.07753358) >> >> # We're going to work with Iceland so set default country >> # (we're creating a new instance but the country variable can be set) >> iceland = CPI(country='Iceland') >> >> # Get CPI in 2012 (not in the data) >> iceland.get(datetime.date(2012,1,1)) ... KeyError: 'Date 2012-01-01 not found in data' >> >> # Get the closest CPI value sintead >> iceland.closest(datetime.date(2012,1,1)) CPI(date=datetime.date(2011, 1, 1), value=155.03663004)
Inflation
>> from inflation_calc.inflation import Inflation >> import datetime >> >> # Create a new Inflation instance >> inflation = Inflation() >> >> # How many US $ would I need in 2011 to pay for what cost $5 in 2007 >> inflation.inflate(5, datetime.date(2011,1,1), datetime.date(2007,1,1), 'United States') 5.424340332378624 >> >> # We can also set the reference year and the country >> usa_2007 = Inflation(reference=datetime.date(2007,1,1), country='United States') >> >> # Get the inflation for 2007 in the United States >> usa_2007.get(datetime.date(2011,1,1)) Inflation(factor=1.0848680664757249, value=0.08486806647572484)
