This looks super cool! Nice addition. Please consider adding either namedtuples or dataclasses for Particle and Coord3D (please change those names to suit your use case). This would make the function signature:

defcenter_of_mass(particles: list[Particle]) ->Coord3D:

Here is a bit of code for creating and using namedtuples:

>>> from collections import namedtuple
>>> Particle = namedtuple("Particle", "x y z mass")
>>> p = Particle(1, 2, 3, 4)
>>> p
Particle(x=1, y=2, z=3, mass=4)
>>> p.mass
4
>>> total_mass = sum(particle.mass for particle in particles)
>>> Coord3D = namedtuple("Coord3D", "x y z")
>>> Coord3D(6, 7, 8)
Coord3D(x=6, y=7, z=8)

I went back to collections.namedtuple(). Thanks for doing this.

This looks super cool! Nice addition. Please consider adding either namedtuples or dataclasses for Particle and Coord3D (please change those names to suit your use case). This would make the function signature:

defcenter_of_mass(particles: list[Particle]) ->Coord3D:

Here is a bit of code for creating and using namedtuples:

>>> from collections import namedtuple
>>> Particle = namedtuple("Particle", "x y z mass")
>>> p = Particle(1, 2, 3, 4)
>>> p
Particle(x=1, y=2, z=3, mass=4)
>>> p.mass
4
>>> total_mass = sum(particle.mass for particle in particles)
>>> Coord3D = namedtuple("Coord3D", "x y z")
>>> Coord3D(6, 7, 8)
Coord3D(x=6, y=7, z=8)
