Ein Pfad-Parameter ist immer erforderlich, weil er Teil des Pfads sein muss.

Sie sollten ihn daher mit `...` deklarieren, um ihn als erforderlich auszuzeichnen.

# Tarefas em segundo plano

Você pode definir tarefas em segundo plano a serem executadas _ após _ retornar uma resposta.

Isso é útil para operações que precisam acontecer após uma solicitação, mas que o cliente realmente não precisa esperar a operação ser concluída para receber a resposta.

Isso inclui, por exemplo:

- Envio de notificações por email após a realização de uma ação:

* `datetime.datetime`:
    * 파이썬의 `datetime.datetime`.
    * 요청과 응답에서 `2008-09-15T15:53:00+05:00`와 같은 ISO 8601 형식의 `str`로 표현됩니다.
* `datetime.date`:
    * 파이썬의 `datetime.date`.
    * 요청과 응답에서 `2008-09-15`와 같은 ISO 8601 형식의 `str`로 표현됩니다.
* `datetime.time`:
    * 파이썬의 `datetime.time`.
    * 요청과 응답에서 `14:23:55.003`와 같은 ISO 8601 형식의 `str`로 표현됩니다.
* `datetime.timedelta`:
    * 파이썬의 `datetime.timedelta`.

Es gibt 3 Hauptalternativen:
