My $0.02 on this discussion: There would be nothing gained by having non-bitwise XOR operator. You can't short-circuit XOR, because you must evaluate all operands to produce a result. Consequently, returning the "true" item also doesn't make much sense. XOR is closer to the the logical NOT operator than it is to AND or OR. Here's my own take on a function that can handle any number of arguments (it should probably raise an exception for 0 or 1 arguments, but I'm lazy): def xor(*operands): if operands: operands = list(operands) a = bool(operands.pop(0)) while operands: b = bool(operands.pop(0)) if a: if b: a = False elif b: a = True return a return False -- http://mail.python.org/mailman/listinfo/python-list
