`yield` kullanan bir dependency içinde `except` ile bir exception yakalar ve bunu tekrar fırlatmazsanız (ya da yeni bir exception fırlatmazsanız), FastAPI normal Python'da olduğu gibi bir exception olduğunu fark edemez:

{* ../../docs_src/dependencies/tutorial008c_an_py310.py hl[15:16] *}

            "mode": "absolute",
            "steps": [
              {
                "color": "green",
                "value": null
              },
              {
                "color": "semi-dark-red",
                "value": 80
              }
            ]
          }
        },
        "overrides": []
      },
      "gridPos": {
        "h": 6,
        "w": 12,
        "x": 0,

Ayrıca normal `def` *path operation function*'ları içinde `async def` dependency tanımlayabilir veya `async def` *path operation function*'ları içinde `def` dependency kullanabilirsiniz vb.

Fark etmez. **FastAPI** ne yapacağını bilir.

/// note | Not

Eğer bilmiyorsanız, dokümanlarda `async` ve `await` için [Async: *"In a hurry?"*](../../async.md#in-a-hurry) bölümüne bakın.

**FastAPI**’nin kendi `HTTPException`’ı vardır.

Ve **FastAPI**’nin `HTTPException` hata sınıfı, Starlette’in `HTTPException` hata sınıfından kalıtım alır (inherit).

Tek fark şudur: **FastAPI**’nin `HTTPException`’ı `detail` alanı için JSON’a çevrilebilir herhangi bir veri kabul ederken, Starlette’in `HTTPException`’ı burada sadece string kabul eder.
