在python中使用列表中的元素创建无序对的所有情况

import itertools

def create_unordered_pairs(elements):
    pairs = []
    for r in range(2, len(elements) + 1):
        combinations = itertools.combinations(elements, r)
        pairs.extend(combinations)
    return pairs

elements = [1, 2, 3, 4]
pairs = create_unordered_pairs(elements)
print(pairs)

[(1, 2), (1, 3), (1, 4), (2, 3), (2, 4), (3, 4), (1, 2, 3), (1, 2, 4), (1, 3, 4), (2, 3, 4), (1, 2, 3, 4)]
