如何将此字典中的所有ID值放入一个列表中？

def extract_ids(dictionary):
    id_list = []
    for key, value in dictionary.items():
        if isinstance(value, dict):
            id_list.extend(extract_ids(value))
        elif isinstance(value, list):
            for item in value:
                if isinstance(item, dict):
                    id_list.extend(extract_ids(item))
                else:
                    id_list.append(item)
        else:
            id_list.append(value)
    return id_list

# 示例字典
example_dict = {
    'key1': 'id1',
    'key2': {
        'subkey1': 'id2',
        'subkey2': ['id3', 'id4']
    },
    'key3': ['id5', 'id6']
}

# 提取ID值列表
id_list = extract_ids(example_dict)
print(id_list)

['id1', 'id2', 'id3', 'id4', 'id5', 'id6']
