Así que, es realmente importante que realmente leas y ejecutes el código, y me hagas saber en los comentarios que lo hiciste. 🤓

### Pydantic v1 y v2 en la misma app { #pydantic-v1-and-v2-on-the-same-app }

No está soportado por Pydantic tener un modelo de Pydantic v2 con sus propios campos definidos como modelos de Pydantic v1 o viceversa.

O valor da variável `PATH` é uma longa string composta por diretórios separados por dois pontos `:` no Linux e macOS, e por ponto e vírgula `;` no Windows.

Por exemplo, a variável de ambiente `PATH` poderia ter esta aparência:

//// tab | Linux, macOS

```plaintext
/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin
```

Pronto también crearemos la verdadera *path operation*.

Si eres un "Pythonista" muy estricto, tal vez no te guste el estilo del nombre del parámetro `tokenUrl` en lugar de `token_url`.
