I am trying to make a point object in 3D in python, and I have the following code

import numpy as np

class Point3D:
    def __init__(self, x, y, z):

        self.vector = np.matrix([x, y, z])
        self.vector.reshape(3, 1)

    def x(self): return self.vector.item((0, 0))
    def y(self): return self.vector.item((0, 1))
    def z(self): return self.vector.item((0, 2))

I am using numpy to create vertical matrices to eventually use this for a rendering engine. I want to be able to reference the x,y and z of this vector without having to type self.vector.item((0, 0)) for example. I want to be able to do point.x and get the x value from the vector automatically. I also want to be able to set the values as such: point.x = 5. Is there any way this possible?

I tried setting them at the start in the init function but then I would have to update it every time. I then made functions to there would only have to be an extra 2 chars, but setting is still not implemented.
