Sum land area grid based on land class grid in Python

Vote count:

0

I have two grids of equal shape, one is for land class and the other is land area.

Examples: Land class [[1 4 3], [3 2 3], [1 3 3]]

Land area [[0.3 0.8 2.0], [5.0 1.5 0.5], [0.1 1.0 3.2]]

I need to sum up land area based on land class, and it would be delightful to print something like this:

1 0.4 2 1.5 3 11.7 4 0.8

The only module I've imported is numpy, and I would like to avoid importing others if possible. Suggestions?
