### 無効な戻り値の型アノテーション { #invalid-return-type-annotations }

しかし、Pydantic型として有効ではない別の任意のオブジェクト（例: データベースオブジェクト）を返し、関数でそのようにアノテーションすると、FastAPIはその型アノテーションからPydanticレスポンスモデルを作成しようとして失敗します。

同様に、<dfn title="複数の型のユニオンは「これらの型のいずれか」を意味します。">ユニオン</dfn>のように、複数の型のうち1つ以上がPydantic型として有効でないものを含む場合も起こります。例えば次は失敗します 💥:

Go is a general-purpose language designed with systems programming

Je pense que `Union[SomeType, None]` est plus explicite quant à sa signification.

Il ne s'agit que des mots et des noms. Mais ces mots peuvent influencer la manière dont vous et vos coéquipiers pensez au code.

À titre d'exemple, prenons cette fonction :

```python
from typing import Optional


def say_hi(name: Optional[str]):
    print(f"Hey {name}!")
```

### Target language

Translate to Portuguese (Português).

Language code: pt.

For instructions or titles in imperative, keep them in imperative, for example "Import FastAPI" to "Importe o FastAPI".

Keep existing translations as they are if the term is already translated.

        // this configuration is on fess_env.properties because this is true only when development
        direction.directDevelopmentHere(fessConfig.isDevelopmentHere());

        // titles of the application for logging are from configurations
        direction.directLoggingTitle(fessConfig.getDomainTitle(), fessConfig.getEnvironmentTitle());

Translate to Spanish (español).

Use the informal grammar (use "tú" instead of "usted").

For instructions or titles in imperative, keep them in imperative, for example "Edit it" to "Edítalo".

For the next terms, use the following translations:

* framework: framework (do not translate to "marco")
* performance: rendimiento
* program (verb): programar
* code (verb): programar
* type hints: anotaciones de tipos
