PythonObject xor PythonObject -- logical exclusive disjunction of Python objects

Description

Perform the logical exclusive disjunction ("xor") operation on Python objects.

i1 : toPython true xor toPython true

o1 = False

o1 : PythonObject of class bool

If one of the arguments is a Macaulay2 object, then it is first converted to a Python object.

i2 : toPython true xor false

o2 = True

o2 : PythonObject of class bool
 
i3 : false xor toPython true

o3 = True

o3 : PythonObject of class bool

Unlike Macaulay2, Python supports using xor with non-boolean objects. If exactly one of the arguments is truthy, then it will return that argument. Otherwise, it will return False.

i4 : toPython 0 xor toPython "foo"

o4 = foo

o4 : PythonObject of class str
 
i5 : toPython 5 xor toPython ""

o5 = 5

o5 : PythonObject of class int
 
i6 : toPython 6 xor toPython "bar"

o6 = False

o6 : PythonObject of class bool
