@blueman010112: You're using the list comprehension wrong: [polygons for polygon in polygons] just repeats the polygons list as many times as there are coordinates in that list. If polygons is already a list of QgsPoints, all you have to do is QgsGeometry.fromMultiPolygon([[polygons]]). I don't understand why you want to use a MultiPolygon for this, though, since you only seem to have one polygon. Maybe it's best if you edit your question with an example of your data.

I still have problem here, I use feature.setGeometry(QgsGeometry.fromMultiPolygon([polygons for polygon in polygons])) where polygons is a list of QgsPoints, but it's still give me same error before, so it's not a list of polygon?
