搜索字典键，嵌套字典中匹配的值，包装在列表中

def search_nested_dict(dictionary, key):
    result = []
    for k, v in dictionary.items():
        if k == key:
            result.append(v)
        elif isinstance(v, dict):
            nested_result = search_nested_dict(v, key)
            result.extend(nested_result)
    return result

data = {
    'key1': 'value1',
    'key2': {
        'key3': 'value2',
        'key4': {
            'key5': 'value3'
        }
    },
    'key6': 'value4'
}

result = search_nested_dict(data, 'key5')
print(result)  # 输出: ['value3']
