If I've got it right, the path class represents a set of bezier curves. This is not exactly what I was looking for. Bezier splines and ordinary polynomial splines are essentially the same thing, of course, but I'd rather find a way to use the latter so that I won't have to do unnecessary conversions. Basically, my problem is that there are a set of points given and I should calculate and draw a cubic spline that interpolates them. My instructor has suggested using Matlab, but I don't have it, and I don't know how to use it. Besides, I always prefer Python, if possible.
