It is a bit verbose though. This variant is shorter on my system[*]:

class Vector:
    def __init__(self, x, y, z):
        self.x = x
        self.y = y
        self.z = z
    def abs(self):
        return math.sqrt(self.x*self.x + self.y*self.y + self.z*self.z)

[*] Windows, they are the same length on Linux.
