## Використання `Annotated` у типі параметра `q`

Пам’ятаєте, як я раніше розповідав, що `Annotated` можна використовувати для додавання метаданих до параметрів у [Вступі до типів Python](../python-types.md#type-hints-with-metadata-annotations){.internal-link target=_blank}?

Зараз саме час використати його разом із FastAPI. 🚀

Раніше ми мали таку анотацію типу:

//// tab | Python 3.10+

```Python
q: str | None = None

Помните, я уже говорил, что `Annotated` можно использовать для добавления метаданных к параметрам в разделе [Введение в типы Python](../python-types.md#type-hints-with-metadata-annotations){.internal-link target=_blank}?

Пришло время использовать его с FastAPI. 🚀

У нас была такая аннотация типа:

//// tab | Python 3.10+

```Python
q: str | None = None
```

Remember I told you before that `Annotated` can be used to add metadata to your parameters in the [Python Types Intro](../python-types.md#type-hints-with-metadata-annotations){.internal-link target=_blank}?

Now it's the time to use it with FastAPI. 🚀

We had this type annotation:

//// tab | Python 3.10+

```Python
q: str | None = None
```

and adjust the corresponding coefficient. if u.IsOdd() == no { rshift1(u, 0) if A.IsOdd() == yes || B.IsOdd() == yes { rshift1(A, A.add(m)) rshift1(B, B.add(a)) } else { rshift1(A, 0) rshift1(B, 0) } } else { // v.IsOdd() == no rshift1(v, 0) if C.IsOdd() == yes || D.IsOdd() == yes { rshift1(C, C.add(m)) rshift1(D, D.add(a)) } else { rshift1(C, 0) rshift1(D, 0) } } if v.IsZero() == yes { return u, A, nil } } } //go:norace func rshift1(a *Nat, carry uint) { size := len(a.limbs) aLimbs := a.limbs[:size]...

  // (as in the case of ConstOp kernel creation on GPU, which involves copying a
  // CPU tensor to GPU).
  // Setting a larger thread pool does not help with the Swift caller, as we use
  // a different TFE context for each thread of execution (for running graph
  // functions, and their send/recvs corountines).
  config.set_inter_op_parallelism_threads(1);

## Verwenden von `Annotated` im Typ für den `q`-Parameter { #use-annotated-in-the-type-for-the-q-parameter }

Erinnern Sie sich, dass ich Ihnen zuvor in [Python-Typen-Intro](../python-types.md#type-hints-with-metadata-annotations){.internal-link target=_blank} gesagt habe, dass `Annotated` verwendet werden kann, um Metadaten zu Ihren Parametern hinzuzufügen?

Jetzt ist es soweit, dies mit FastAPI zu verwenden. 🚀

Lembra que eu disse antes que `Annotated` pode ser usado para adicionar metadados aos seus parâmetros na [Introdução aos tipos do Python](../python-types.md#type-hints-with-metadata-annotations){.internal-link target=_blank}?

Agora é a hora de usá-lo com FastAPI. 🚀

Tínhamos esta anotação de tipo:

//// tab | Python 3.10+

```Python
q: str | None = None
```

				writeErrorResponse(r.Context(), w, errorCodes.ToAPIErr(errCode), r.URL)
				atomic.AddUint64(&globalHTTPStats.rejectedRequestsTime, 1)
				return
			}
			// Verify if the request date header is shifted by less than globalMaxSkewTime parameter in the past
			// or in the future, reject request otherwise.
			curTime := UTCNow()
			if curTime.Sub(amzDate) > globalMaxSkewTime || amzDate.Sub(curTime) > globalMaxSkewTime {

    for (i in 0 until messageCount) {
      serverListener.assertBinaryMessage(message)
    }
    serverListener.assertClosing(1001, "")

    // When the server acknowledges the close the connection shuts down gracefully.
    server.close(1000, null)
    clientListener.assertClosing(1000, "")
    clientListener.assertClosed(1000, "")
    serverListener.assertClosed(1001, "")
  }
