## Motivación

Comencemos con un ejemplo simple:

```Python
{!../../docs_src/python_types/tutorial001.py!}
```

Llamar este programa nos muestra el siguiente <abbr title="en español: salida">output</abbr>:

```
John Doe
```

La función hace lo siguiente:

* Toma un `first_name` y un `last_name`.
* Convierte la primera letra de cada uno en una letra mayúscula con `title()`.

* `app`: el objeto creado dentro de `main.py` con la línea `app = FastAPI()`.
* `--reload`: hace que el servidor se reinicie cada vez que cambia el código. Úsalo únicamente para desarrollo.

///

En el output, hay una línea que dice más o menos:

```hl_lines="4"
INFO:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
```

Esa línea muestra la URL dónde se está sirviendo tu app en tu maquina local.

- kubeadm: Added support for machine-readable output with `-o yaml` and `-o json` to the command `kubeadm certs check-expiration`. This change is introduced in a new API: ``` kind: CertificateExpirationInfo apiVersion: output.kubeadm.k8s.io/v1alpha3 ``` The existing non-structured formatting is preserved. The output API version v1alpha2 is now deprecated and will be removed in a future release. Please migrate to using v1alpha3.

             * to populate fields if the writeXxx operation needs this header data

    **Note:** You can add `--test_sharding_strategy=disabled` to the `flags` to
    disable the sharding so that all the test outputs are in one file. However,
    it may slow down the tests for not running in parallel and may cause the
    test to timeout but it could be useful when you need to execute a single

 * Converter.apply (like Converter.convert) is capable of accepting null inputs. However, a
 * supertype of `Function<A, B>` turns out to be massively more useful to callers in practice: They
 * want their output to be non-null in operations like `stream.map(myConverter)`, and we can
 * guarantee that as long as we also require the input type to be non-null[*] (which is a
 * requirement that existing callers already fulfill).
