Need help with replace item at index of a list

[nkiakas]

Good evening.

I am trying to replace some items of a list with other items from another list, where the indices are also in another list. As you can see from the attachments, i am not defining something proper…
Do i have to do something with the levels of the lists, or the way of lacing?
Thank you for your time

Hey,
Try feeding it into a Python Script Node instead

lst = IN[0][:]  # original list
indexes = IN[1]
items = IN[2]

for i, item in zip(indexes, items):
    lst[i] = item

OUT = lst

clockwork works the way expected.
