Sets each bit to 1 if only one of two bits is 1 Sets each bit to 1 if one of two bits is 1 Returns True if both variables are not the same objectīitwise operators are used to compare binary numbers. Returns True if both variables are the same object Identity operators are used to compare the objects to see if they are actually the same object with the same memory location.
