gehen, so ist das das gleiche wie die URL:

```
http://127.0.0.1:8000/items/?skip=0&limit=10
```

Aber wenn Sie zum Beispiel zu:

```
http://127.0.0.1:8000/items/?skip=20
```

gehen, werden die Parameter-Werte Ihrer Funktion sein:

* `skip=20`: da Sie das in der URL gesetzt haben
* `limit=10`: weil das der Defaultwert ist
