What's the idiomatic way to do maximumBy (higher order function taking a comparison function for the test), on a list of lists, where the comparison we want to make is the sum of the list, in Python?

Here's a Haskell implementation and example output:

> maximumBy (compare `on` sum) [[1,2,3],[4,5,6],[1,3,5]]
> [4,5,6]
