그렇지 않으면 `/users/{user_id}`는 `/users/me` 요청 또한 매개변수 `user_id`의 값이 `"me"`인 것으로 "생각하게" 됩니다.

## 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.

	// The primary group should not change from RID 513 here either
	// but the group will be called "None" instead:
	// https://www.adampalmer.me/iodigitalsec/2013/08/10/windows-null-session-enumeration/
	// "Group 'None' (RID: 513)"
	u, e := syscall.UTF16PtrFromString(username)
	if e != nil {
		return "", e
	}
	d, e := syscall.UTF16PtrFromString(domain)
	if e != nil {
		return "", e
	}

```

それ以外の場合、 `/users/{users_id}` は `/users/me` としてもマッチします。値が「"me"」であるパラメータ `user_id` を受け取ると「考え」ます。

## 定義済みの値

*パスパラメータ*を受け取る *path operation* をもち、有効な*パスパラメータ*の値を事前に定義したい場合は、標準のPython <abbr title="Enumeration">`Enum`</abbr> を利用できます。

### `Enum` クラスの作成

`Enum` をインポートし、 `str` と `Enum` を継承したサブクラスを作成します。

`str` を継承することで、APIドキュメントは値が `文字列` でなければいけないことを知り、正確にレンダリングできるようになります。

// StatefulSetUpdateStrategyType is a string enumeration type that enumerates
// all possible update strategies for the StatefulSet controller.

		}
		b, _, _ := isWindows.Call(uintptr(hwnd))
		if b == 0 {
			t.Error("USER32.IsWindow returns FALSE")
		}
		counter++
		return 1 // continue enumeration
	})
	a, _, _ := d.Proc("EnumWindows").Call(cb, 888)
	if a == 0 {
		t.Error("USER32.EnumWindows returns FALSE")
	}
	if counter == 0 {
		t.Error("Callback has been never called or your have no windows")
	}

			delete(e.shardsBySvc[serviceName], namespace)
		}
		if len(e.shardsBySvc[serviceName]) == 0 {
			delete(e.shardsBySvc, serviceName)
		}
	}
	epShards.Unlock()
}
