Status: New Owner: ---- Labels: Type-Defect Priority-Medium New issue 1483 by hastebrot: no xor in sympy.core.basic for new logic module http://code.google.com/p/sympy/issues/detail?id=1483
I wonder why there is no xor in the new logic module, resp. in sympy.core.basic. Is this intentional? into sympy/core/basic.py: def __xor__(self, other): """Overloading for ^ operator""" from sympy.logic.boolalg import Or, And, Not return And(Or(self, other), Not(And(self, other))) test it in the console: >>> a, b = symbols("ab") >>> a ^ b And(Or(a, b), Or(Not(a), Not(b))) looks strange after normalisation. I see the problem, that creating a Xor class into sympy.logic.boolalg (for better readability) is redundant, since it uses fundamental logical operators (and, or, not) which are already defined. so is it better to put only the fundamental ones into the modules? -- You received this message because you are listed in the owner or CC fields of this issue, or because you starred this issue.
