OUT = dim

the input node accepts only one input what should i need to change to make node accepts list inputs ???

i know the question is too simple but i may get permision to work on python with this node

You have a few options. You can modify the input line of code a little bit and add a for loop.

items = UnwrapElement(IN[0])

for item in items:
     line = item.GeometryCurve

Or you can wrap the python code in a custom node (if it’s not already) and set the lacing to Longest. Modifying the code may also require a few more changes to make your list structure work but both are viable options.
