### Попередження про заміну

Це означає, що якщо Ви хочете оновити елемент `bar`, використовуючи `PUT` з тілом:

```Python
{
    "name": "Barz",
    "price": 3,
    "description": None,
}
```

оскільки він не містить вже збереженого атрибута `"tax": 20.2`, модель введення прийме значення за замовчуванням `"tax": 10.5`.

І дані будуть збережені з цим "новим" значенням `tax` = `10.5`.

		{"ad", "", ObjectInfo{}, BucketNameInvalid{Bucket: "ad"}, false},
		// Test cases with valid but non-existing bucket names (Test number 5-6).
		{"abcdefgh", "abc", ObjectInfo{}, BucketNotFound{Bucket: "abcdefgh"}, false},
		{"ijklmnop", "efg", ObjectInfo{}, BucketNotFound{Bucket: "ijklmnop"}, false},

    * `dict`의 값(value)는 `float`타입이다. (각 아이템의 가격(price))

#### `Optional`

`str`과 같이 타입을 선언할 때 `Optional`을 쓸 수도 있는데, "선택적(Optional)"이기때문에 `None`도 될 수 있습니다:

```Python hl_lines="1  4"
{!../../docs_src/python_types/tutorial009.py!}
```

`Optional[str]`을 `str` 대신 쓰게 되면, 특정 값이 실제로는 `None`이 될 수도 있는데 항상 `str`이라고 가정하는 상황에서 에디터가 에러를 찾게 도와줄 수 있습니다.

#### Generic(제네릭) 타입

이 타입은 대괄호 안에 매개변수를 가지며, 종류는:

* `List`

            // Some SMB implementations may allow this, which is non-standard but acceptable for testing
            log.info("Non-empty directory deletion succeeded (non-standard behavior, but acceptable in Docker/Samba)");
        } catch (SmbException e) {
            // This is the expected behavior per SMB specification
            deletionFailed = true;

Some requests will have a cached response. When this cached response isn’t fresh, OkHttp can do a _conditional GET_ to download an updated response if it’s newer than what’s cached. This requires headers like `If-Modified-Since` and `If-None-Match` to be added.

## Rewriting Responses

			return false

		// if one of source or target is non MinIO, just replicate the top most version like `mc mirror`
