응답 모델은 아래와 같이 기본값을 가질 수 있습니다:

{* ../../docs_src/response_model/tutorial004_py310.py hl[9,11:12] *}

* `description: Union[str, None] = None` (또는 Python 3.10에서 `str | None = None`)은 기본값으로 `None`을 갖습니다.
* `tax: float = 10.5`는 기본값으로 `10.5`를 갖습니다.
* `tags: List[str] = []`는 기본값으로 빈 리스트 `[]`를 갖습니다.

하지만 실제로 저장되지 않았을 경우 결과에서 이를 생략하고 싶을 수 있습니다.

#### Muhtemelen `None` { #possibly-none }

Bir değerin `str` gibi bir tipi olabileceğini ama aynı zamanda `None` da olabileceğini bildirebilirsiniz.

```

```

Це означає, що `item` може бути `int` або `str`.

#### Можливо `None` { #possibly-none }

Ви можете оголосити, що значення може мати тип, наприклад `str`, але також може бути `None`.

### 3.1 Handle Types
```java
public enum HandleType {
    NONE(0),                    // No durability
    DURABLE_V1(1),              // SMB 2.1 - survives network loss
    DURABLE_V2(2),              // SMB 3.0 - with timeout
    PERSISTENT(3);              // SMB 3.0 - survives server reboot

// Returns nil if the bytes are invalid or empty.
// AppendTo() can append a serialized Checksum to another already-serialized Checksum,
// however, in practice, we only use one at a time.
// ChecksumFromBytes only returns the first one and no part checksums.
func ChecksumFromBytes(b []byte) *Checksum {
	if len(b) == 0 {
		return nil

	// Read checksum type
	t, n := binary.Uvarint(b)
