Das ist nützlich, wenn Sie Schlüssel empfangen, deren Namen Sie nicht bereits kennen.

Ein anderer nützlicher Anwendungsfall ist, wenn Sie Schlüssel eines anderen Typs haben wollen, z. B. `int`.

Das schauen wir uns mal an.

Im folgenden Beispiel akzeptieren Sie irgendein `dict`, solange es `int`-Schlüssel und `float`-Werte hat.

@REM do not let MAVEN_PROJECTBASEDIR end with a single backslash which would escape the double quote. This happens when .mvn at drive root.

## Use `StaticFiles` { #use-staticfiles }

* Import `StaticFiles`.
* "Mount" a `StaticFiles()` instance in a specific path.

/// note | Technical Details

You could also use `from starlette.staticfiles import StaticFiles`.

**FastAPI** provides the same `starlette.staticfiles` as `fastapi.staticfiles` just as a convenience for you, the developer. But it actually comes directly from Starlette.
