Xor Operator

 

Definition: Performs a logical exclusion on two expressions.

 

The XOR operator is a crazy one. XOR evaluates two expressions and returns Trueif the two are different; that is, if one expression is True and the other expression is False. If both expression are true (or false) then XOR returns False.

·          23 is less than 12

·          12 is greater than 40
