### Поле `examples` у JSON Schema

Пізніше JSON Schema додала поле <a href="https://json-schema.org/draft/2019-09/json-schema-validation.html#rfc.section.9.5" class="external-link" target="_blank">`examples`</a> у нову версію специфікації.

І вже OpenAPI 3.1.0 базується на цій новій версії (JSON Schema 2020-12), яка включає поле `examples`.

```Python hl_lines="3"
import os

name = os.getenv("MY_NAME", "World")
print(f"Hello {name} from Python")
```

/// tip

El segundo argumento de <a href="https://docs.python.org/3.8/library/os.html#os.getenv" class="external-link" target="_blank">`os.getenv()`</a> es el valor por defecto a retornar.

Si no se proporciona, es `None` por defecto; aquí proporcionamos `"World"` como el valor por defecto para usar.

* The translation doesn't seem to change the original content, for example with obvious additional documentation sections.
* The translation doesn't use different Markdown structures, for example adding HTML tags when the original didn't have them.
* The "admonition" sections, like `tip`, `info`, etc. are not changed or translated. For example:

```
/// tip

This is a tip.
