Python 'for' Loop

Hi all, am new to scripting in python, was wondering how to recreate this effect (attached) within one Python component.

My approach looks something like this:

import rhinoscriptsyntax as rs

clsdcrv = []
clsdcrv.append(x)

for i in range (0,z):

    explodedCurves = []
    explodedCurves = rs.ExplodeCurves(clsdcrv, True)

    pts = []

    for curve in explodedCurves:
        parameter = rs.CurveParameter(curve, t)
        point_on_curve = rs.EvaluateCurve(curve, parameter)
        pts.append(point_on_curve)
    pts.append(pts[0])
    a = rs.AddPolyline(pts)
    clsdcrv.append(a)

Guessed I should have explained, made those images with the builtin grasshopper components by

1) evaluating curve edges at a certain parameter

2) then making a polyline that goes through the points from the evaluatecrv,

3) then doing step 1 on the polyline over and over until I got that result

I was wondering how you would do the same thing within the ghpython component? The approach I am taking doesn't seem to loop right when I set the range higher than 1, any idea what's wrong?
