이때 "첫 글자를 대문자로 바꾸는 함수"를 호출해야 합니다.

`upper`였나? 아니면 `uppercase`? `first_uppercase`? `capitalize`?

그때 개발자들의 오랜 친구, 에디터 자동완성을 시도해봅니다.

당신은 `first_name`를 입력한 뒤 점(`.`)을 입력하고 자동완성을 켜기 위해서 `Ctrl+Space`를 눌렀습니다.

하지만 슬프게도 아무런 도움이 되지 않습니다:

### 타입 추가하기

이전 버전에서 한 줄만 수정해봅시다.

저희는 이 함수의 매개변수 부분:

```Python
    first_name, last_name
```

# Header Parameter Models

If you have a group of related **header parameters**, you can create a **Pydantic model** to declare them.

This would allow you to **re-use the model** in **multiple places** and also to declare validations and metadata for all the parameters at once. 😎

/// note

This is supported since FastAPI version `0.115.0`. 🤓

# "TFCI_MACOS_BAZEL_TEST_DIR_PATH" specifies the directory that Bazel should use
