Apparently both the string representation and the hash *are* available before calling init: sage: P_init = Parent(category=Rings()) sage: P_init <type 'sage.structure.parent.Parent'> sage: hash(P_init) 6922428270616034436 sage: P_no_init = Parent.__new__(Parent, category=Rings()) sage: P_no_init <type 'sage.structure.parent.Parent'> sage: hash(P_no_init) 6922428270616034436 Here, I demonstrate that P_no_init is really not initialised: sage: P_init._is_category_initialized() True sage: P_no_init._is_category_initialized() False So, the result is the same with and without initialisation, and indeed the hash *is* called before the initialisation is finished. Thank you for the links!
