### Besser mit `Annotated`

@app.put("/items/{item_id}")
def update_item(item_id: int, item: Item):
    return {"item_name": item.name, "item_id": item_id}
```

A szerver automatikusan újraindul (mert hozzáadtuk a --reload paramétert a fenti `uvicorn` parancshoz).

pkg syscall (freebsd-386-cgo), type Kevent_t struct, Filter int16
pkg syscall (freebsd-386-cgo), type Kevent_t struct, Flags uint16
pkg syscall (freebsd-386-cgo), type Kevent_t struct, Ident uint32

pkg syscall (freebsd-386-cgo), type Msghdr struct
pkg syscall (freebsd-386-cgo), type Msghdr struct, Control *uint8

関数の最初のパラメータとして`*`を渡します。

Pythonはその`*`で何かをすることはありませんが、それ以降のすべてのパラメータがキーワード引数（キーと値のペア）として呼ばれるべきものであると知っているでしょう。それは<abbr title="From: K-ey W-ord Arg-uments"><code>kwargs</code></abbr>としても知られています。たとえデフォルト値がなくても。

## 数値の検証: 以上

Python won't do anything with that `*`, but it will know that all the following parameters should be called as keyword arguments (key-value pairs), also known as <abbr title="From: K-ey W-ord Arg-uments"><code>kwargs</code></abbr>. Even if they don't have a default value.
