Analyze empty lists and sublists

Good morning.
I have a problem when parsing empty lists with empty sublists…
I want to be able to check if the list and sublists are empty…?
but the problem occurs when using the parsing node… it doesn’t keep the number of elements parsed and reduces it… I want the number of elements not to be lost… how could I perform said operation…?
something in Python??
Thanks a lot…
