O *modelo de dados* `HeroUpdate` é um pouco especial, ele tem **todos os mesmos campos** que seriam necessários para criar um novo hero, mas todos os campos são **opcionais** (todos têm um valor padrão). Dessa forma, quando você atualizar um hero, poderá enviar apenas os campos que deseja atualizar.

Como todos os **campos realmente mudam** (o tipo agora inclui `None` e eles agora têm um valor padrão de `None`), precisamos **declarar novamente** todos eles.

        has been moved to the GitHub repository
        [keras-team/keras](http://github.com/keras-team/keras). The API
        endpoints for `tf.keras` stay unchanged, but are now backed by the
        `keras` PIP package. All Keras-related PRs and issues should now be
        directed to the GitHub repository.

#### Mais detalhes

Digamos que seu arquivo se chama `myapp.py`.

Se você executá-lo com:

<div class="termy">

```console
$ python myapp.py
```

</div>

então a variável interna `__name__` no seu arquivo, criada automaticamente pelo Python, terá como valor a string `"__main__"`.

Então, a seção:

```Python
    uvicorn.run(app, host="0.0.0.0", port=8000)
```

vai executar.
