그리고 여러분이 원하는 무엇이든 반환할 수 있습니다.

이 경우, 이 의존성은 다음과 같은 경우를 기대합니다:

* 선택적인 쿼리 매개변수 `q`, `str`을 자료형으로 가집니다.
* 선택적인 쿼리 매개변수 `skip`, `int`를 자료형으로 가지며 기본 값은 `0`입니다.
* 선택적인 쿼리 매개변수 `limit`,`int`를 자료형으로 가지며 기본 값은 `100`입니다.

그 후 위의 값을 포함한 `dict` 자료형으로 반환할 뿐입니다.

/// info | 정보

FastAPI는 0.95.0 버전부터 `Annotated`에 대한 지원을 (그리고 이를 사용하기 권장합니다) 추가했습니다.

from datetime import date

from pydantic import BaseModel

# 宣告一個變數為 string
# 並在函式中獲得 editor support
def main(user_id: str):
    return user_id


# 宣告一個 Pydantic model
class User(BaseModel):
    id: int
    name: str
    joined: date
```


可以像這樣來使用：

```python
my_user: User = User(id=3, name="John Doe", joined="2018-07-19")

second_user_data = {
    "id": 4,
    "name": "Mary",

	}

	resp := CheckPartsResp{
		// By default, all results have an unknown status
		Results: make([]int, len(fi.Parts)),
	}

	for i, part := range fi.Parts {
		resp.Results[i], err = xioutil.WithDeadline[int](ctx, globalDriveConfig.GetMaxTimeout(), func(ctx context.Context) (int, error) {
			return s.checkPart(volumeDir, path, fi.DataDir, part.Number, fi.Erasure.ShardFileSize(part.Size), skipAccessChecks(volume)), nil
