I'm not sure I understand your question, but here is a way to group a list into sub-lists, each with three members(the last list may have fewer):

grouped_lst = [lst[x:x+3] for x in range(0, len(lst), 3)]

Hi Shridhar, I don't speak Parseltongue so I cannot help you with your script, but I don't think Grasshopper supports pointclouds at all.
Or did you just mean 'multiple points'...?

If you post the file that you are working with it will be easier to debug.

If I have to guess, you need an output on your ghPython component called grouped_lst (or whatever name you assign the list of grouped points.)

a = (x[:y]) is the one liner in the py comp. the idea is to slice points into 3 groups and mesh em.
