Semua validasi data dikerjakan di belakang layar oleh <a href="https://docs.pydantic.dev/" class="external-link" target="_blank">Pydantic</a>, sehingga anda mendapatkan banyak kemudahan. Anda juga tahu proses ini akan ditangani dengan baik.

Anda bisa mendeklarasikan tipe data dengan `str`, `float`, `bool` dan banyak tipe data kompleks lainnya.

Beberapa tipe di atas akan dibahas pada bab berikutnya tutorial ini.

## Urutan berpengaruh

We could create an instance of this class with:

{* ../../docs_src/dependencies/tutorial011_an_py39.py hl[18] *}

And that way we are able to "parameterize" our dependency, that now has `"bar"` inside of it, as the attribute `checker.fixed_content`.

## Use the instance as a dependency { #use-the-instance-as-a-dependency }

	// For negative length read everything.

	// Reply back invalid range if the input offset and length fall out of range.

	// Get start part index and offset.

value is shown here). The user is then redirected to the OpenID provider's login page and performs necessary login actions (e.g. entering credentials, responding to MFA authentication challenges, etc). After successful login, the user is redirected back to the MinIO console. This redirect URL is specified as a parameter by MinIO when the user is redirected to the OpenID Provider in the beginning. For some setups, extra configuration may be required for this step to work correctly.

For a simple...

이는 **FastAPI**가 다음과 유사한 본문을 기대한다는 것을 의미합니다:

```JSON
{
    "name": "Foo",
    "description": "The pretender",
    "price": 42.0,
    "tax": 3.2,
    "tags": ["rock", "metal", "bar"],
    "image": {
        "url": "http://example.com/baz.jpg",
        "name": "The Foo live"
    }
}
```

다시 한번, **FastAPI**를 사용하여 해당 선언을 함으로써 얻는 것은:

* 중첩 모델도 편집기 지원(자동완성 등)
* 데이터 변환
* 데이터 검증
