Save looped outputs in a list


i need to save the output of looped data in a list. Those are curves in my function.
Thats because i am drawing some global vectorpoints, creating a curve and then i have to delete some points again, but have to keep the curve. If i loop it several times i can just manage to keep in the end some curves where i didnt delete one of their points along the way.

Is there any way to keep some of the looped data somehow?

Thank you very much!

Got solved by himself.
