//// tab | Python 3.9+

In Python 3.9 ist `Annotated` ein Teil der Standardbibliothek, Sie können es von `typing` importieren.

```Python hl_lines="1  4"

//// tab | Python 3.8+

In Versionen niedriger als Python 3.9 importieren Sie `Annotated` von `typing_extensions`.

                newApi("Method", "SourceKt.setBazool(boolean)"),
                newApi("Method", "SourceKt.setFool(boolean)")
            )
        }

        // new file-facade class can be annotated with @Incubating, members must be annotated with @since
        checkBinaryCompatible(
            v2 = {
                withFile(
                    "kotlin/com/example/Source.kt",
                    """

from fastapi import FastAPI, Query
from fastapi.testclient import TestClient
from typing_extensions import Annotated

from .utils import needs_py310


def get_client():
    app = FastAPI()
    with pytest.warns(DeprecationWarning):

        @app.get("/items/")
        async def read_items(
            q: Annotated[str | None, Query(regex="^fixedquery$")] = None,
        ):
            if q:

```

...the bigger the codebase, the more noticeable it is.

Now you can create an annotated dependency once, like this:

```Python
CurrentUser = Annotated[User, Depends(get_current_user)]
```

And then you can reuse this `Annotated` dependency:

```Python
CurrentUser = Annotated[User, Depends(get_current_user)]


@app.get("/items/")
def read_items(user: CurrentUser):

Depending on your use case, you might prefer to use a different library, but if you asked me, I would probably suggest you try **Strawberry**.

Here's a small preview of how you could integrate Strawberry with FastAPI:

defaultConfig:
  proxyMetadata:
    # should be overridden by the command
    ISTIO_META_DNS_CAPTURE: "false"
    # should be overridden by the annotation on the WorkloadGroup
    PROXY_CONFIG_ANNOT_VALUE: "foo"
    # should be in the final cluster.env/mesh.yaml

  // resource. This replaces the deprecated `kubernetes.io/ingress.class`
  // annotation. For backwards compatibility, when that annotation is set, it
  // must be given precedence over this field. The controller may emit a
  // warning if the field and annotation have different values.
  // Implementations of this API should ignore Ingresses without a class
