我需要组合两个列表，其中有一个相似的列和第二个唯一的列

def combine_lists(list1, list2, similar_column):
    combined_list = []
    for item1 in list1:
        found_match = False
        for item2 in list2:
            if item1[similar_column] == item2[similar_column]:
                combined_item = {**item1, **item2}  # 合并两个字典
                combined_list.append(combined_item)
                found_match = True
                break
        if not found_match:
            combined_list.append(item1)
    
    for item2 in list2:
        found_match = False
        for item1 in list1:
            if item2[similar_column] == item1[similar_column]:
                found_match = True
                break
        if not found_match:
            combined_list.append(item2)
    
    return combined_list

# 示例数据
list1 = [
    {"id": 1, "name": "A", "age": 20},
    {"id": 2, "name": "B", "age": 25},
    {"id": 3, "name": "C", "age": 30}
]

list2 = [
    {"id": 2, "address": "X", "phone": "123"},
    {"id": 4, "address": "Y", "phone": "456"}
]

similar_column = "id"

combined_list = combine_lists(list1, list2, similar_column)
print(combined_list)

[
    {"id": 1, "name": "A", "age": 20},
    {"id": 2, "name": "B", "age": 25, "address": "X", "phone": "123"},
    {"id": 3, "name": "C", "age": 30},
    {"id": 4, "address": "Y", "phone": "456"}
]
