Resumindo, você declara **uma vez** os tipos dos parâmetros, corpo etc. como parâmetros de função.

Você faz isso com os tipos padrão do Python moderno.

Você não terá que aprender uma nova sintaxe, os métodos ou classes de uma biblioteca específica etc.

Apenas **Python** padrão.

Por exemplo, para um `int`:

```Python
item_id: int
```

ou para um modelo mais complexo, `Item`:

Normalerweise befinden sich die **Paketanforderungen** für Ihre Anwendung in einer Datei.

Dies hängt hauptsächlich von dem Tool ab, mit dem Sie diese Anforderungen **installieren**.

Die gebräuchlichste Methode besteht darin, eine Datei `requirements.txt` mit den Namen der Packages und deren Versionen zu erstellen, eine pro Zeile.

```JSON
{"item_id": 5, "q": "somequery"}
```

Artık şunları yapan bir API oluşturdunuz:

* `/` ve `/items/{item_id}` _path_'lerinde HTTP request'leri alır.
* Her iki _path_ de `GET` operasyonlarını (HTTP _method_'ları olarak da bilinir) kabul eder.
* `/items/{item_id}` _path_'i, `int` olması gereken `item_id` adlı bir _path parameter_'a sahiptir.
* `/items/{item_id}` _path_'i, opsiyonel `str` bir _query parameter_ olan `q`'ya sahiptir.

			if len(etag) >= 32 && strings.Count(etag, "-") != 1 {
				etag = etag[len(etag)-32:]
			}
		}
	}

	// We must not use the http.Header().Set method here because some (broken)
	// clients expect the ETag header key to be literally "ETag" - not "Etag" (case-sensitive).
	// Therefore, we have to set the ETag directly as map entry.
