JSON은 오직 `str`형 키만 지원한다는 것을 염두에 두세요.

하지만 Pydantic은 자동 데이터 변환이 있습니다.

즉, API 클라이언트가 문자열을 키로 보내더라도 해당 문자열이 순수한 정수를 포함하는한 Pydantic은 이를 변환하고 검증합니다.

그러므로 `weights`로 받은 `dict`는 실제로 `int` 키와 `float` 값을 가집니다.

///

## 요약

**FastAPI**를 사용하면 Pydantic 모델이 제공하는 최대 유연성을 확보하면서 코드를 간단하고 짧게, 그리고 우아하게 유지할 수 있습니다.

물론 아래의 이점도 있습니다:

* 편집기 지원 (자동완성이 어디서나!)

This means that, even though your API clients can only send strings as keys, as long as those strings contain pure integers, Pydantic will convert them and validate them.

And the `dict` you receive as `weights` will actually have `int` keys and `float` values.

///

## Recap

With **FastAPI** you have the maximum flexibility provided by Pydantic models, while keeping your code simple, short and elegant.

```Python hl_lines="2"
@app.get('/')
def results():
    results = some_library()
    return results
```

Wenn Ihre Anwendung (irgendwie) mit nichts anderem kommunizieren und auf dessen Antwort warten muss, verwenden Sie `async def`.

Wenn Sie sich unsicher sind, verwenden Sie einfach `def`.

* Die API überprüft den `username` und das `password` und antwortet mit einem „Token“ (wir haben davon noch nichts implementiert).
    * Ein „Token“ ist lediglich ein String mit einem Inhalt, den wir später verwenden können, um diesen Benutzer zu verifizieren.
    * Normalerweise läuft ein Token nach einiger Zeit ab.

        // If we think this might be a 'chaining' call then we allow the return value to either
        // be the wrapper or the returnValue.
        if (!isPossibleChainingCall || wrapper != actualReturnValue) {

## Separating tests

In a real application, you probably would have your tests in a different file.

And your **FastAPI** application might also be composed of several files/modules, etc.

### **FastAPI** app file

Let's say you have a file structure as described in [Bigger Applications](bigger-applications.md){.internal-link target=_blank}:
