In python you would use name mangling to hide parts of the interface
from the public.

class Point3D:
    def __init__(self):
        self.__x = 0.0
        self.__y = 0.0
        self.__z = 0.0

    def __setPoint(x,y,z):
        self.__x = x
        self.__y = y
        self.__z = z

    def __getPoint(x,y,z):
        x = self.__x
        y = self.__y
        z = self.__z

p = Point3D()
p.__setPoint(1,2,3)

# ...
# AttributeError: Point3D instance has no attribute '__setPoint'
