### Lance o `HTTPException` no seu código.

`HTTPException`, ao fundo, nada mais é do que a conjunção entre uma exceção comum do Python e informações adicionais relevantes para APIs.

E porque é uma exceção do Python, você não **retorna** (return) o `HTTPException`, você lança o (raise) no seu código.

### Was ist ein Programm?

Das Wort **Programm** wird häufig zur Beschreibung vieler Dinge verwendet:

* Der **Code**, den Sie schreiben, die **Python-Dateien**.
* Die **Datei**, die vom Betriebssystem **ausgeführt** werden kann, zum Beispiel: `python`, `python.exe` oder `uvicorn`.

### Використання `HTTPException` у коді

`HTTPException` — це звичайна помилка Python із додатковими даними, які стосуються API.

Оскільки це помилка Python, Ви не `повертаєте` його, а `генеруєте` (генеруєте помилку).

/// tip

Here we use <a href="https://docs.python.org/3/library/time.html#time.perf_counter" class="external-link" target="_blank">`time.perf_counter()`</a> instead of `time.time()` because it can be more precise for these use cases. 🤓

* 나중에 재사용할 수 있는 `templates` 객체를 생성합니다.
* 템플릿을 반환할 경로 작업에 `Request` 매개변수를 선언합니다.
* 생성한 `templates`를 사용하여 `TemplateResponse`를 렌더링하고 반환합니다. 템플릿의 이름, 요청 객체 및 Jinja2 템플릿 내에서 사용될 키-값 쌍이 포함된 "컨텍스트" 딕셔너리도 전달합니다.

/// note | 참고

FastAPI 0.108.0 이전과 Starlette 0.29.0에서는 `name`이 첫 번째 매개변수였습니다.

또한 이전 버전에서는 `request` 객체가 Jinja2의 컨텍스트에서 키-값 쌍의 일부로 전달되었습니다.
