通过两个重复的元素对元组的嵌套列表进行分组

def group_tuples(tuples):
    groups = {}
    for tup in tuples:
        key = (tup[0], tup[1])
        if key in groups:
            groups[key].append(tup)
        else:
            groups[key] = [tup]
    return list(groups.values())

# 示例数据
tuples = [(1, 2), (3, 4), (1, 2), (5, 6), (3, 4), (7, 8)]

# 调用函数进行分组
result = group_tuples(tuples)

# 输出结果
for group in result:
    print(group)

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