### El archivo de configuración { #the-config-file }

Proveniente del ejemplo anterior, tu archivo `config.py` podría verse como:

{* ../../docs_src/settings/app02_an_py39/config.py hl[10] *}

Nota que ahora no creamos una instance por defecto `settings = Settings()`.

### El archivo principal de la app { #the-main-app-file }

            throw new CrawlingAccessException("Failed to parse " + url, e);
        }
    }

    /**

        assertNull(restriction.getUpperBound(), CHECK_UPPER_BOUND);
        assertFalse(restriction.isUpperBoundInclusive(), CHECK_UPPER_BOUND_INCLUSIVE);

        // TODO test reversed restrictions on all below
        range1 = VersionRange.createFromVersionSpec("[1.0,)");
        range2 = VersionRange.createFromVersionSpec("1.1");
        mergedRange = range1.restrict(range2);

Por supuesto, usarías las mismas ideas que leíste en [Acerca de las versiones de FastAPI](versions.md){.internal-link target=_blank} para establecer los rangos de versiones.

Por ejemplo, tu `requirements.txt` podría verse así:

```
fastapi[standard]>=0.113.0,<0.114.0
pydantic>=2.7.0,<3.0.0
```

Y normalmente instalarías esas dependencias de los paquetes con `pip`, por ejemplo:

<div class="termy">

```console

      try {
        cls = classInfo.load();
      } catch (NoClassDefFoundError e) {
        // In case there were linking problems, this is probably not a class we care to test anyway.
        logger.log(Level.SEVERE, "Cannot load class " + classInfo + ", skipping...", e);
        continue;
      }
      if (!cls.isInterface()) {
        classes.add(cls);
      }
    }
    return classes;
  }

// Again, the chance of this happening is cryptographically negligible. if s.IsZero() == 1 { return nil, errors.New("ecdsa: internal error: s is zero") } return &Signature{r.Bytes(c.N), s.Bytes(c.N)}, nil } // inverse sets kInv to the inverse of k modulo the order of the curve. func inverse[P Point[P]](c *Curve[P], kInv, k *bigmod.Nat) { if c.ordInverse != nil { kBytes, err := c.ordInverse(k.Bytes(c.N)) // Some platforms don't implement ordInverse, and always return an error. if err == nil { _, err...

### Usar el SDK { #using-the-sdk }

Ahora puedes importar y usar el código del cliente. Podría verse así, nota que tienes autocompletado para los métodos:

También obtendrás autocompletado para el payload a enviar:
