在元组列表中分组和查找相同的元素？

# 创建元组列表
tuple_list = [(1, 2), (3, 4), (1, 2), (5, 6), (3, 4), (7, 8)]

# 创建字典，统计元素出现的次数
count_dict = {}
for tuple in tuple_list:
    if tuple in count_dict:
        count_dict[tuple] += 1
    else:
        count_dict[tuple] = 1

# 创建集合，将具有相同值的键分组在一起
group_set = set()
for key, value in count_dict.items():
    if value > 1:
        group_set.add(key)

# 查找元素所在的分组
search_element = (3, 4)
result_group = []
for key in group_set:
    if search_element in key:
        result_group.append(key)

print("分组结果：", result_group)
