Helloooo everybody ! Here is the problem I met today:
sage: F = FiniteEnumeratedSet(("a","b","c")); F {'a', 'b', 'c'} sage: isinstance(F,Parent) True sage: F[0] 'a' sage: F[0].parent() --------------------------------------------------------------------------- AttributeError Traceback (most recent call last) <ipython-input-15-142f29211c68> in <module>() ----> 1 F[Integer(0)].parent() AttributeError: 'str' object has no attribute 'parent' Soooooooo sometimes you write code that applies to parents, and sometimes the elements know what their parents are, sometimes they don't.... 1) Is that normal ? 2) If not, what do we do against it ? Have fun ! Nathann -- You received this message because you are subscribed to the Google Groups "sage-combinat-devel" group.
