P2.2.1The XOR operator

There is no exclusive-or operator provided "out of the box" by Python, but one can be constructed from the existing operators. Find two different ways of doing this. (The XOR truth table is provided below).

P	Q	P xor Q
True	True	False
False	True	True
True	False	True
False	False	False

Show solution

The following is equivalent to the missing exclusive-or operator a xor b

(not a and b) or (not b and a)

Alternatively, if a and b are boolean values, a != b is the same as the above. If they are not, they must be converted first:

bool(a) != bool(b)
