# 파이썬 타입 소개

파이썬은 선택적으로 "타입 힌트(type hints)"를 지원합니다.

이러한 **타입 힌트**들은 변수의 <abbr title="예를 들면: str, int, float, bool">타입</abbr>을 선언할 수 있게 해주는 특수한 구문입니다.

변수의 타입을 지정하면 에디터와 툴이 더 많은 도움을 줄 수 있게 됩니다.

이 문서는 파이썬 타입 힌트에 대한 **빠른 자습서 / 내용환기** 수준의 문서입니다. 여기서는 **FastAPI**를 쓰기 위한 최소한의 내용만을 다룹니다.

**FastAPI**는 타입 힌트에 기반을 두고 있으며, 이는 많은 장점과 이익이 있습니다.

비록 **FastAPI**를 쓰지 않는다고 하더라도, 조금이라도 알아두면 도움이 될 것입니다.

Once the **patch** is successfully applied, developer must run tests to validate the fix that was backported by running following tests, locally.

Unit tests

```
λ make test
```

Verify different type of MinIO deployments work

```
λ make verify
```

Verify if healing and replacing a drive works

```
λ make verify-healing
```
