accessor/mutator functions

If the class had two attributes--x and y--would the code look like
something lik this:

 class C(object):
        def __init__(self):
            self.__x = 0
            self.__y = 0
        def getx(self):
            return self.__x
        def setx(self, x):
            if x < 0: x = 0
            self.__x = x
        def gety(self):
            return self.__y
        def sety(self, y):
            if y < 0: y = 0
            self.__y = y
        x = property(getx, setx)
        y = property(gety, sety)

?

Because if so, does the term 'lazy evaluation' refer to the fact that
instead of:

C().getx()
C().gety()
C().setx(10)
C().sety(10)

one would substitute:

C().x
C().y
C().x = 10
C().y = 10
