geoJSON: How to create FeatureCollection with dynamic number of Features?

I have a list of of Features (all Points) in a list in Python. The Features are dynamic stemming from database data which is updated on a 30 minutes interval. Hence I never have a static number of features.

I need to generate a Feature Collection with all Features in my list. However (as far as I know) the syntax for creating a FeatureCollection wants you to pass it all the features.

ie:

FeatureClct = FeatureCollection(feature1, feature2, feature3)

How does one generate a FeatureCollection without knowing how many features there will be beforehand? Is there a way to append Features to an existing FeatureCollection?

According to the documentation of python-geojson (which i guess you are using, you didn't mention it) you can also pass a list to FeatureCollection, just put all the results into a list and you're good to go:

feature1 = Point((45, 45));
feature2 = Point((-45, -45));

features = [feature1, feature2];

collection = FeatureCollection(features);
