And then adding the extra keyword argument `hashed_password=hashed_password`, like in:

```Python
UserInDB(**user_in.dict(), hashed_password=hashed_password)
```

...ends up being like:

```Python
UserInDB(
    username = user_dict["username"],
    password = user_dict["password"],
    email = user_dict["email"],
    full_name = user_dict["full_name"],
    hashed_password = hashed_password,
)
```

#### `dict`の展開と追加引数

そして、追加のキーワード引数`hashed_password=hashed_password`を以下のように追加すると:

```Python
UserInDB(**user_in.dict(), hashed_password=hashed_password)
```

...以下のようになります:

```Python
UserInDB(
    username = user_dict["username"],
    password = user_dict["password"],
    email = user_dict["email"],
    full_name = user_dict["full_name"],
    hashed_password = hashed_password,
)
```

#### Распаковка `dict` и дополнительные именованные аргументы

И затем, если мы добавим дополнительный именованный аргумент `hashed_password=hashed_password` как здесь:

```Python
UserInDB(**user_in.dict(), hashed_password=hashed_password)
```

... то мы получим что-то подобное:

```Python
UserInDB(
    username = user_dict["username"],
    password = user_dict["password"],

FE48          ; disallowed_STD3_mapped ; 005D          # 4.0  PRESENTATION FORM FOR VERTICAL RIGHT SQUARE BRACKET
FE49..FE4C    ; disallowed_STD3_mapped ; 0020 0305     # 1.1  DASHED OVERLINE..DOUBLE WAVY OVERLINE
FE4D..FE4F    ; disallowed_STD3_mapped ; 005F          # 1.1  DASHED LOW LINE..WAVY LOW LINE
FE50          ; disallowed_STD3_mapped ; 002C          # 1.1  SMALL COMMA

```Python
UserInDB(**user_in.dict(), hashed_password=hashed_password)
```

...acaba sendo como:

```Python
UserInDB(
    username = user_dict["username"],
    password = user_dict["password"],
    email = user_dict["email"],
    full_name = user_dict["full_name"],
    hashed_password = hashed_password,
)
```
