As others have said, ^ is for XOR. That's buried here in the documentation: http://docs.python.org/release/2.7/reference/expressions.html#binary-bitwise-operations Not that I would have expected you to find it there since that's pretty dense. In fact, older versions of the Python doc used to describe this section as "for language lawyers" but I see they've changed that now. BTW the more common name for this character is caret (ka-RAY).
