signal processing - calculate exponential moving average in python -


I have dates and each measure of each of those dates, I want to calculate an exponential moving average for each date. Do anyone know how to do this?

I'm new to Python. It does not appear that the average standard is created in Python Library, which kills me in a weird way. Maybe I'm not looking at the right place.

So, the following code is given, how can I calculate the average points running in calendar dates? 

  date time import date from days = [date (2008,1,1), date (2008,1,2), date (2008,1,7)] IQ = [110, 105, 90]

(Perhaps a better way to structate the data, any advice would be appreciated)

Example: 

  $ python26 \ n (.mp (str, iqdata)) print (smooth (iqdata, alpha = 0.5)) Smooth.py IQData ( Date = datetime.date (2008, 1, 1), iq = 110) IQData (date = datetime.date (2008, 1, 2), iq = 105) IQData (date = datetime.date (2008), 1, 7), iq = 90) 95.0 < / Code>
