I would like to know if there's a way to list weak compositions in SageMath Similar to: list(Compositions(2, length=2)) The result is: [[1, 1]] I would like to have: [[1, 1],[2, 0],[0, 2]]

IntegerVectors do that. E.g. IntegerVectors(2,2).list() give [[2, 0], [1, 1], [0, 2]] as requested.

It would be nice to have a "See also: IntegerVectors" in the documentation for Compositions.

I see such "See also" there. Don't you?
