(Readability is
supposed to be one of the major selling points of Python). But, this is
probably good enough.
In the words of those greater than myself, "Not every one-liner needs
to be in the standard library."
def xor(a, b):
return bool(a) != bool(b)
Let's see...
and returns the last object that is "true"
or returns the first object that is "true"
so should xor return the only object that is "true", else False/None?
def xor(a, b)
if a and b:
return None
elif a:
return a
elif b:
return b
else:
return None
How about:
def xor(a, b):
return not b and a or not a and b
