```Python
with open("./somefile.txt") as f:
    contents = f.read()
    print(contents)
```

Под капотом" open("./somefile.txt") создаёт объект называемый "контекстным менеджером".

Когда блок `with` завершается, он обязательно закрывает файл, даже если были исключения.

```Python
with open("./somefile.txt") as f:
    contents = f.read()
    print(contents)
```

Underneath, the `open("./somefile.txt")` creates an object that is called a "Context Manager".

When the `with` block finishes, it makes sure to close the file, even if there were exceptions.

- Fixed an issue where kubectl doesn't print image volume when kubectl describe a pod with that volume. ([#126706](https://github.com/kubernetes/kubernetes/pull/126706), [@carlory](https://github.com/carlory))

### Langkah 5: hasilkan konten

{* ../../docs_src/first_steps/tutorial001.py hl[8] *}

Anda bisa menghasilkan `dict`, `list`, nilai singular seperti `str`, `int`, dll.

Anda juga bisa menghasilkan model Pydantic (anda akan belajar mengenai ini nanti).

**FastAPI**는 각각을 인지하고 데이터를 옳바른 위치에 가져올 것입니다.

{* ../../docs_src/body/tutorial004_py310.py hl[16] *}

함수 매개변수는 다음을 따라서 인지하게 됩니다:

* 만약 매개변수가 **경로**에도 선언되어 있다면, 이는 경로 매개변수로 사용될 것입니다.
* 만약 매개변수가 (`int`, `float`, `str`, `bool` 등과 같은) **유일한 타입**으로 되어있으면, **쿼리** 매개변수로 해석될 것입니다.
* 만약 매개변수가 **Pydantic 모델** 타입으로 선언되어 있으면, 요청 **본문**으로 해석될 것입니다.

/// note | 참고

FastAPI는 `q`의 값이 필요없음을 알게 될 것입니다. 기본 값이 `= None`이기 때문입니다.

### Passo 5: retorne o conteúdo

{* ../../docs_src/first_steps/tutorial001.py hl[8] *}

Você pode retornar um `dict`, `list` e valores singulares como `str`, `int`, etc.

Você também pode devolver modelos Pydantic (você verá mais sobre isso mais tarde).
