### Trabajando con *enumeraciones* de Python { #working-with-python-enumerations }

El valor del *path parameter* será un *miembro* de enumeración.

#### Comparar *miembros* de enumeraciones { #compare-enumeration-members }

Puedes compararlo con el *miembro* de enumeración en tu enum creada `ModelName`:

Con `pwdlib`, incluso podrías configurarlo para poder leer contraseñas creadas por **Django**, un plug-in de seguridad de **Flask** u otros muchos.

Así, podrías, por ejemplo, compartir los mismos datos de una aplicación de Django en una base de datos con una aplicación de FastAPI. O migrar gradualmente una aplicación de Django usando la misma base de datos.

  private static long saturatedCast(BigInteger big) {
    if (big.compareTo(MAX_LONG) > 0) {
      return Long.MAX_VALUE;
    }
    if (big.compareTo(MIN_LONG) < 0) {
      return Long.MIN_VALUE;
    }
    return big.longValue();
  }
