Answer 1

You can use set() method to remove duplicates from the list of tuples.

 >>> items = [(8, 8), (8, 8), (8, 8), (8, 8), (8, 8),
(6, 7), (7, 7), (7, 7), (7, 6), (6, 7),
(2, 12), (12, 3), (3, 4), (4, 12), (12, 12)]
>>> set_items = set(items)
>>> set_items
{(6, 7), (7, 6), (12, 12), (7, 7), (8, 8), (4, 12), (2, 12), (3, 4), (12, 3)}
