Problem with forecasting a stationary time series with Python:

Hi guys!

I need to forecast a time series with Statsmodels but I have a stationary time series with seasonality. Theoretically it should be easier if I have a stationary time series, but I am having a lot of difficulties.

On internet there are a lot of examples of forecasting with non stationary time series, but but I haven’t found any examples with stationary time series.

Who can give me an example of forecasting with a stationary time series?
