For convenient, I would like to add an attribute, upper_bounds, to Poset objects
However, after writing the method and issue Poset.upper_bounds = upper_bounds X.upper_bounds(S) complains 'FinitePoset_with_category' object has no attribute 'upper_bounds' When I try FinitePoset_with_category.upper_bounds = upper_bounds I got name 'FinitePoset_with_category' is not defined So how can one add an attribute to FinitePoset_with_category? -- You received this message because you are subscribed to the Google Groups "sage-support" group.
