        response = spy(response);

/// tip | Consejo

La sintaxis `{"name", "description"}` crea un `set` con esos dos valores.

Es equivalente a `set(["name", "description"])`.

#### Usar `list`s en lugar de `set`s { #using-lists-instead-of-sets }

Más adelante la mejoraremos aumentando la seguridad y versatilidad con **múltiples modelos** a continuación. 🤓

### Crear Modelos { #create-models }

Importa `SQLModel` y crea un modelo de base de datos:

{* ../../docs_src/sql_databases/tutorial001_an_py310.py ln[1:11] hl[7:11] *}

La clase `Hero` es muy similar a un modelo de Pydantic (de hecho, en el fondo, realmente *es un modelo de Pydantic*).
