프로젝트 작업을 마쳤다면 가상 환경을 **비활성화**할 수 있습니다.

<div class="termy">

```console
$ deactivate
```

</div>

이렇게 하면 `python`을 실행할 때, 해당 가상 환경과 그 안에 설치된 패키지에서 실행하려고 하지 않습니다.

## 작업할 준비 완료 { #ready-to-work }

이제 프로젝트 작업을 시작할 준비가 되었습니다.

// If the pointer sent to done is non-nil AND the error
// is either nil or io.EOF the disk is considered good.
// So if unsure if the disk status is ok, return nil as a parameter to done.
// Shadowing will work as long as return error is named: https://go.dev/play/p/sauq86SsTN2

因此，我们通过 `..` 对依赖项使用了相对导入：
