I there a more efficient way of printing ?

[DeaD_EyE]

Complete different approach, not only about printing/representation. Requires Python 3.7+
The dataclass decorator makes a nice representation from a class and some other convenient stuff. In addition, usually you want to keep points together in a tuple, a sequence or mapping. If you have more than one point, it's better to keep x, y and z together in one object.

from dataclasses import dataclass

@dataclass
class Point:
    x: int
    y: int
    z: int


point1 = Point(1, 2, 3)
point2 = Point(x=-5, y=10, z=5)

print(point1)
print(point2)

If you want to sort Points by x, y and z, dataclass needs the extra argument order. The Argument frozen will prevent assigning new objects to the Point object. Then the dataclass behaves like a tuple.

from dataclasses import dataclass

@dataclass(order=True, frozen=True)
class Point:
    x: int
    y: int
    z: int


point1 = Point(1, 2, 3)
point2 = Point(x=-5, y=10, z=5)

sorted_points = sorted([point1, point2])
print(sorted_points)
