Beachten Sie, dass wir in diesem Fall eine Standard-Python-Funktion `open()` verwenden, die mit einer Datei interagiert.

Es handelt sich also um I/O (Input/Output), welches „Warten“ erfordert, bis Dinge auf die Festplatte geschrieben werden.

Aber `open()` verwendet nicht `async` und `await`.

Daher deklarieren wir die Eventhandler-Funktion mit Standard-`def` statt mit `async def`.

// User represents information about user.
type User struct {
	Name    string `json:"username"`
	ID      string `json:"id"`
	Enabled bool   `json:"enabled"`
}

// Standard errors.
var (
	ErrNotImplemented     = errors.New("function not implemented")
	ErrAccessTokenExpired = errors.New("access_token expired or unauthorized")
)

### Összefoglalás

Összegzésül, deklarálod **egyszer** a paraméterek, body, stb típusát funkciós paraméterekként.

Ezt standard modern Python típusokkal csinálod.

Nem kell új szintaxist, vagy specifikus könyvtár mert metódósait, stb. megtanulnod.

Csak standard **Python**.

Például egy `int`-nek:

```Python
item_id: int
```

Egy komplexebb `Item` modellnek:

```Python

// similar attributes and is identified by a pair of strings: the name of the FlowSchema and a "flow distinguisher".
message FlowSchema {
  // `metadata` is the standard object's metadata.
  // More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#metadata
  // +optional
  optional k8s.io.apimachinery.pkg.apis.meta.v1.ObjectMeta metadata = 1;

                    return Lists.newArrayList(Sets.newTreeSet(insertionOrder));
                  }
                })
            .named("ForwardingSortedSet[SafeTreeSet] with standard implementations")
            .withFeatures(
                CollectionSize.ANY,
                CollectionFeature.KNOWN_ORDER,
                CollectionFeature.GENERAL_PURPOSE)
            .createTestSuite());

# GraphQL

As **FastAPI** is based on the **ASGI** standard, it's very easy to integrate any **GraphQL** library also compatible with ASGI.

You can combine normal FastAPI *path operations* with GraphQL on the same application.

/// tip

**GraphQL** solves some very specific use cases.

It has **advantages** and **disadvantages** when compared to common **web APIs**.

		APICode: "kms:NotSupported",
		Err:     "requested functionality is not supported",
	}
)

// Error is a KMS error that can be translated into an S3 API error.
//
// It does not implement the standard error Unwrap interface for
// better error log messages.
type Error struct {
	Code    int    // The HTTP status code returned to the client
	APICode string // The API error code identifying the error

		"Invalid storage class value",
		"Please check the value",
		`MINIO_STORAGE_CLASS_STANDARD: Format "EC:<Default_Parity_Standard_Class>" (e.g. "EC:3"). This sets the number of parity drives for MinIO server in Standard mode. Objects are stored in Standard mode, if storage class is not defined in Put request

Isso é provavelmente o que você faria quando você quisesse lançar sua aplicação em produção:

```
pip install fastapi
```

Também instale o `uvicorn` para funcionar como servidor:

```
pip install "uvicorn[standard]"
```

E o mesmo para cada dependência opcional que você quiser usar.

Falcon est un autre framework Python haute performance, il est conçu pour être minimal, et est utilisé comme fondation pour d'autres frameworks comme Hug.

Il utilise le standard précédent pour les frameworks web Python (WSGI) qui est synchrone, donc il ne peut pas gérer les WebSockets et d'autres cas d'utilisation. Néanmoins, il offre de très bonnes performances.
