I have a two column list like: 2,131 6,335 7,6 8,9 10,131 131,99 5,10
And I want to store it in a tree-like structure. So if I request 131, it should return all the child of 131, like 2, 10 and 5 (since 5 is child of 10). If I request 335, it should return: 6 and 7. If I request 9, it should return 8. I guess I could use tuples or dictionaries to do it, but I can't figure out how. Best, SB. -- Sebastián Bassi Diplomado Ciencia y Tecnología.
