In other words, this function classifies all the things present in any of the input sets, into similar classes, based on which sets things are a member of. If sort=True, return class sets are sorted by decreasing size and their natural sort order within each class size. Otherwise, class sets are returned in the order that they were identified, which is generally not significant. >>> classify([]) == ([], {}) True >>> classify([[]]) == ([], {}) True >>> classify([[], []]) == ([], {}) True >>> classify([[1]]) == ([{1}], {1: {1}}) True >>> classify([[1,2]]) == ([{1, 2}], {1: {1, 2}, 2: {1, 2}}) True >>> classify([[1],[2]]) == ([{1}, {2}], {1: {1}, 2: {2}}) True >>> classify([[1,2],[2]]) == ([{1}, {2}], {1: {1}, 2: {2}}) True >>> classify([[1,2],[2,4]]) == ([{1}, {2}, {4}], {1: {1}, 2: {2}, 4: {4}}) True >>> classify([[1,2],[2,4,5]]) == ( ...
