Making a series of circles on a curve with grasshopper and python

Hi guys,

i started using python in grasshopper not long ago. Right now I am trying to create a series of chain linked circles with increasing radius on a rail curve. And the centre of each circle is determined by the intersection of previous circle and the rail curve. I was hoping to create something like the evaluate length component in grasshopper which will create a set of points on a curve. And i was hoping my will work with a set of given values as distance between points. I have made the grasshopper definition of it as shown in the files attached. Meanwhile when i tried to recreate it in python but i can’t get it to work. can someone help me with this?test evaluate distance.gh (23.9 KB)
