Use one list as search key for another list with sublist of list

[jc4d]

Thank you for your time and answer
I wanted to go further and then compare the first item of the vector's list only so I tried the code bellow but I get a TypeError:

S = set(tuple(x[1]) for x in list1[0])
result = [x for x in list2[0] if tuple(x[1]) not in S]
