You can define the (HTTP) `status_code` to be used in the response of your *path operation*.

You can pass directly the `int` code, like `404`.

## 프로젝트 생성

먼저, 프로젝트를 위한 디렉터리를 하나 생성합니다.

보통 사용자 홈 디렉터리 안에 `code`라는 디렉터리를 만들고, 그 안에 프로젝트마다 하나씩 디렉터리를 만들어 관리합니다.

<div class="termy">

```console
// 홈 디렉터리로 이동
$ cd
// 모든 코드 프로젝트를 위한 디렉터리 생성
$ mkdir code
// code 디렉터리로 이동
$ cd code
// 이번 프로젝트를 위한 디렉터리 생성
$ mkdir awesome-project
// 해당 프로젝트 디렉터리로 이동
$ cd awesome-project
```
