```Usually I never do someones homework!!

liste[n_] :== RandomReal[{0, 1}, {n, 3}];
points[n_] :== With[{pts == liste[n]}, Graphics3D[{PointSize[0.03], Table[
{Hue[i/n], Point[pts[[i]]]}, {i, 1, n}]},
PlotRange -> {{0, 1}, {0, 1}, {0, 1}}]
];
ligne[n_] :==
With[{pts == liste[n]}, Graphics3D[{Line[pts], PointSize[0.03], Table[
{Hue[i/n], Point[pts[[i]]]}, {i, 1, n}]},
PlotRange -> {{0, 1}, {0, 1}, {0, 1}}]
]
