/// info | 정보

`EmailStr`을 사용하려면 먼저 [`email-validator`](https://github.com/JoshData/python-email-validator)를 설치하세요.

[가상 환경](../virtual-environments.md)을 생성하고, 활성화한 다음 설치해야 합니다. 예를 들어:

```console
$ pip install email-validator
```

또는 다음과 같이:

```console
$ pip install "pydantic[email]"
```

SwitchableHttpClient (extends FaultTolerantClient)

4. Run `mvn formatter:format license:format test`
5. Update JavaDoc for changed/new classes

**Principles:**
- Avoid over-engineering - keep solutions simple
- Only expose necessary public APIs
- Validate parameters with `Objects.requireNonNull()`
- Provide detailed error messages with context
- Add logging with contextual information
