如何将键控2列表列表转换为相同键控N列表列表？

def convert_lists(lists):
    # Step 1: 获取所有唯一键
    unique_keys = list(set([key for sublist in lists for key in sublist.keys()]))

    # Step 2: 创建字典
    key_value_dict = {}

    # Step 3: 添加键值对到字典
    for sublist in lists:
        for key, value in sublist.items():
            if key in key_value_dict:
                key_value_dict[key].append(value)
            else:
                key_value_dict[key] = [value]

    # Step 4: 转换为相同键控N列表列表
    n_lists = []
    for key in unique_keys:
        n_lists.append({key: key_value_dict.get(key, [])})

    return n_lists

# 示例数据
lists = [
    [{"key1": "value1"}, {"key2": "value2"}],
    [{"key2": "value3"}, {"key3": "value4"}],
    [{"key1": "value5"}, {"key3": "value6"}]
]

# 转换为相同键控N列表列表
result = convert_lists(lists)

print(result)

[{'key1': ['value1', 'value5']}, {'key2': ['value2', 'value3']}, {'key3': ['value4', 'value6']}]
