### Tags com Enums

Se você tem uma grande aplicação, você pode acabar acumulando **várias tags**, e você gostaria de ter certeza de que você sempre usa a **mesma tag** para *operações de rota* relacionadas.

Nestes casos, pode fazer sentido armazenar as tags em um `Enum`.

**FastAPI** suporta isso da mesma maneira que com strings simples:

 *
 * <p>For example, an XML escaper would convert the literal string {@code "Foo<Bar>"} into {@code
 * "Foo&lt;Bar&gt;"} to prevent {@code "<Bar>"} from being confused with an XML tag. When the
 * resulting XML document is parsed, the parser API will return this text as the original literal
 * string {@code "Foo<Bar>"}.
 *

            }
            ASN1TaggedObject tagged = (ASN1TaggedObject) vec.getObjectAt(1);
            if (tagged.getTagNo() != 0) {
                throw new IOException("Malformed SPNEGO token: tag " + tagged.getTagNo() + " " + tagged);
            }
            ASN1Sequence sequence = ASN1Sequence.getInstance(tagged, true);
            final Enumeration<ASN1Object> fields = sequence.getObjects();

Pass `*`, as the first parameter of the function.

Python won't do anything with that `*`, but it will know that all the following parameters should be called as keyword arguments (key-value pairs), also known as <abbr title="From: K-ey W-ord Arg-uments"><code>kwargs</code></abbr>. Even if they don't have a default value.
