That is not the same as declaring default values like would be with:

```Python
    first_name="john", last_name="doe"
```

It's a different thing.

We are using colons (`:`), not equals (`=`).

And adding type hints normally doesn't change what happens from what would happen without them.

But now, imagine you are again in the middle of creating that function, but with type hints.

 *
 * <p>The views returned by {@link #column}, {@link #columnKeySet()}, and {@link #columnMap()} have
 * iterators that don't support {@code remove()}. Otherwise, all optional operations are supported.
 * Null row keys, columns keys, and values are not supported.
 *
 * <p>Lookups by row key are often faster than lookups by column key, because the data is stored in

    implements Serializable {

  /**
   * Returns a {@code Collector} that accumulates elements into an {@code ImmutableTable}. Each
   * input element is mapped to one cell in the returned table, with the rows, columns, and values
   * generated by applying the specified functions.
   *
   * <p>The returned {@code Collector} will throw a {@code NullPointerException} at collection time

## Validation additionnelle

Nous allons imposer que bien que `q` soit un paramètre optionnel, dès qu'il est fourni, **sa longueur n'excède pas 50 caractères**.

## Importer `Query`

Pour cela, importez d'abord `Query` depuis `fastapi` :

`app.add_middleware()` recebe uma classe de middleware como o primeiro argumento e quaisquer argumentos adicionais a serem passados para o middleware.

## Middlewares Integrados

**FastAPI** inclui vários middlewares para casos de uso comuns, veremos a seguir como usá-los.

Para o próximo exemplo, você também poderia usar `from starlette.middleware.something import SomethingMiddleware`.
