Why can't I xor strings?

I'm guessing the OP has already guessed this solution from the variety already 
provided, but the direct translation of this statement would be:

bool(x) ^ bool(y)

for example:

>>> bool("") ^ bool("a")
True
>>> bool("") ^ bool("")
False
>>> bool("a") ^ bool("a")
False
>>> bool("a") ^ bool("")
True
