These dependencies can `raise` exceptions, the same as normal dependencies:

함수는 예외를 `return`하는 것이지 `raise`하지 않는다는 점에 유의하세요. 예외를 발생시키는(`raise`) 작업은 내부 코드의 나머지 부분에서 수행됩니다.

### Lance o `HTTPException` no seu código { #raise-an-httpexception-in-your-code }

`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.

### Eine `HTTPException` in Ihrem Code auslösen { #raise-an-httpexception-in-your-code }

`HTTPException` ist eine normale Python-Exception mit zusätzlichen Daten, die für APIs relevant sind.

Weil es eine Python-Exception ist, geben Sie sie nicht zurück (`return`), sondern lösen sie aus (`raise`).

    hero = session.get(Hero, hero_id)
    if not hero:
        raise HTTPException(status_code=404, detail="Hero not found")
    return hero


@app.delete("/heroes/{hero_id}")
def delete_hero(hero_id: int, session: Session = Depends(get_session)):
    hero = session.get(Hero, hero_id)
    if not hero:
        raise HTTPException(status_code=404, detail="Hero not found")
    session.delete(hero)
