Yes, that's possible too :-)

You can open your shapefile as a vector layer and then use its
provider to add some features:
layer = QgsVectorLayer(...)
provider = layer.getDataProvider()
provider.addFeatures( [ feature ] )

And that's it. I didn't try it now but should work as expected.
addFeatures() expects list of features, but of course you can add them
one by one.
