Sure!

The k-means algorithms tries to group the points, but how can we know to
which group a point has been assigned?
What I mean is that, on the output, I would like to color the points with
the same color as the centroid they "depend" on.

And another question, which I thought could be related to the first one, is
why does the algorithms returns the objective function? What's its use?

Thanks ffor spending time for my questions :)
