### Tags with Enums

If you have a big application, you might end up accumulating **several tags**, and you would want to make sure you always use the **same tag** for related *path operations*.

In these cases, it could make sense to store the tags in an `Enum`.

**FastAPI** supports that the same way as with plain strings:

## 사전정의 값

만약 *경로 매개변수*를 받는 *경로 작동*이 있지만, *경로 매개변수*로 가능한 값들을 미리 정의하고 싶다면 파이썬 표준 <abbr title="열거형(Enumeration)">`Enum`</abbr>을 사용할 수 있습니다.

### `Enum` 클래스 생성

`Enum`을 임포트하고 `str`과 `Enum`을 상속하는 서브 클래스를 만듭니다.

`str`을 상속함으로써 API 문서는 값이 `string` 형이어야 하는 것을 알게 되고 이는 문서에 제대로 표시됩니다.

가능한 값들에 해당하는 고정된 값의 클래스 어트리뷰트들을 만듭니다:

```Python hl_lines="1  6-9"

### 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:

file_identifier "TFL3";
// File extension of any written files.
file_extension "tflite";

// IMPORTANT: All new members of tables, enums and unions must be added at the
// end to ensure backwards compatibility.

// The type of data stored in a tensor.
enum TensorType : byte {
  FLOAT32 = 0,
  FLOAT16 = 1,
  INT32 = 2,
  UINT8 = 3,
  INT64 = 4,
  STRING = 5,
  BOOL = 6,
  INT16 = 7,

		}
		for co := 0; co < len(ord.coprimes); co++ {
			enum := ord.start(uint32(co))
			checked := make([]bool, procs)
			for p := 0; p < procs; p++ {
				x := enum.position()
				if checked[x] {
					println("procs:", procs, "inc:", enum.inc)
					panic("duplicate during enumeration")
				}
				checked[x] = true
				enum.next()
			}
			if !enum.done() {
				panic("not done")
			}
		}
	}
