Ahora sabes que debes corregirlo, convertir `age` a un string con `str(age)`:

## Declaración de tipos

Acabas de ver el lugar principal para declarar anotaciones de tipos. Como parámetros de función.

Este también es el lugar principal donde los utilizarías con **FastAPI**.

### Tipos simples

        if (thrown == suppressed) {
          return;
        }
        try {
          thrown.addSuppressed(suppressed);
        } catch (Throwable e) {
          /*
           * A Throwable is very unlikely, but we really don't want to throw from a Suppressor, so
           * we catch everything. (Any Exception is either a RuntimeException or

 * hint, so this technique may fail at the whim of the JDK implementation, for example if a user
 * specified the JVM flag {@code -XX:+DisableExplicitGC}. But in practice, it works very well for
 * ordinary tests.
 *
 * <p>Failure of the expected event to occur within an implementation-defined "reasonable" time
 * period or an interrupt while waiting for the expected event will result in a {@link

**FastAPI** la usa para que, si usas un modelo Pydantic en `response_model`, y tus datos tienen un error, lo verás en tu log.

Pero el cliente/usuario no lo verá. En su lugar, el cliente recibirá un "Error Interno del Servidor" con un código de estado HTTP `500`.

        param("env.GRADLE_INTERNAL_REPO_URL", "%gradle.internal.repository.url%")
        if (os == Os.MACOS && arch == Arch.AMD64) {
            // Use fewer parallel forks only on Intel macOS builds, since they are not very powerful.
            param("maxParallelForks", "2")
        }
        if (os == Os.LINUX || os == Os.MACOS) {
            param("env.LC_ALL", "en_US.UTF-8")
        }
    }
}

					var successVersions, failVersions int
					for _, ver := range fiv.Versions {
						stopFn := globalScannerMetrics.timeSize(scannerMetricHealAbandonedVersion)
						err := bgSeq.queueHealTask(healSource{
							bucket:    bucket,
							object:    fiv.Name,
							versionID: ver.VersionID,
						}, madmin.HealItemObject)
						stopFn(int(ver.Size))
						if !isErrObjectNotFound(err) && !isErrVersionNotFound(err) {

// if the status is not ok.
TF_CAPI_EXPORT extern int TF_OpIsStateful(const char* op_type,
                                          TF_Status* status);

// Platform specific initialization routine. Very few platforms actually require
// this to be called.
TF_CAPI_EXPORT void TF_InitMain(const char* usage, int* argc, char*** argv);

// Platform-specific implementation to return an unused port. (This should used

**Concurrencia** y **paralelismo** ambos se relacionan con "diferentes cosas sucediendo más o menos al mismo tiempo".

Pero los detalles entre *concurrencia* y *paralelismo* son bastante diferentes.

Para ver la diferencia, imagina la siguiente historia sobre hamburguesas:

Vas con tu crush a conseguir comida rápida, te pones en fila mientras el cajero toma los pedidos de las personas frente a ti. 😍

FastAPI is a modern, fast (high-performance), web framework for building APIs with Python based on standard Python type hints.

The key features are:

* **Fast**: Very high performance, on par with **NodeJS** and **Go** (thanks to Starlette and Pydantic). [One of the fastest Python frameworks available](#performance).
* **Fast to code**: Increase the speed to develop features by about 200% to 300%. *

 * <h3>Invertibility</h3>
 *
 * <p>The reverse operation <b>may</b> be a strict <i>inverse</i> (meaning that {@code
 * converter.reverse().convert(converter.convert(a)).equals(a)} is always true). However, it is very
 * common (perhaps <i>more</i> common) for round-trip conversion to be <i>lossy</i>. Consider an
 * example round-trip using {@link com.google.common.primitives.Doubles#stringConverter}:
