* Porque las estructuras de datos de pydantic son solo instances de clases que defines; autocompletado, linting, mypy y tu intuición deberían funcionar correctamente con tus datos validados.
* Valida **estructuras complejas**:
    * Uso de modelos jerárquicos de Pydantic, `List` y `Dict` de `typing` de Python, etc.
    * Y los validadores permiten definir, verificar y documentar de manera clara y fácil esquemas de datos complejos como JSON Schema.

## OAuth2 scopes and OpenAPI { #oauth2-scopes-and-openapi }

The OAuth2 specification defines "scopes" as a list of strings separated by spaces.

The content of each of these strings can have any format, but should not contain spaces.

These scopes represent "permissions".

In OpenAPI (e.g. the API docs), you can define "security schemes".

When one of these security schemes uses OAuth2, you can also declare and use scopes.

If you use Hypercorn, it also has the option `--root-path`.

/// note | Technical Details

The ASGI specification defines a `root_path` for this use case.

And the `--root-path` command line option provides that `root_path`.
