Hello,

I am new to python scripting in Rhino/Grasshopper. I am confused about a certain issue. I have a mix of geometries (Curves, breps ets) and which are connected to the python component as"list access". I am iterating over this list to make a new list of first 3 curves. However, the output shows a tree with same 3 curves being repeated 5 times. What is going wrong in the code? See attached image.
