& ⤴️ ❎ ➕ 🇨🇻 ❌ `hashed_password=hashed_password`, 💖:

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

...🔚 🆙 💆‍♂ 💖:

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

    disabled: Union[bool, None] = None


class UserInDB(User):
    hashed_password: str


pwd_context = CryptContext(schemes=["bcrypt"], deprecated="auto")

oauth2_scheme = OAuth2PasswordBearer(tokenUrl="token")

app = FastAPI()


def verify_password(plain_password, hashed_password):
    return pwd_context.verify(plain_password, hashed_password)


def get_password_hash(password):

    disabled: bool | None = None


class UserInDB(User):
    hashed_password: str


pwd_context = CryptContext(schemes=["bcrypt"], deprecated="auto")

oauth2_scheme = OAuth2PasswordBearer(tokenUrl="token")

app = FastAPI()


def verify_password(plain_password, hashed_password):
    return pwd_context.verify(plain_password, hashed_password)


def get_password_hash(password):

async def read_pet(pet_id: int):
    user = UserDB(
        email="******@****.***",
        hashed_password="secrethashed",
    )
    pet = PetDB(name="Nibbler", owner=user)
    return pet


@app.get("/pets/", response_model=List[PetOut])
async def read_pets():
    user = UserDB(
        email="******@****.***",
        hashed_password="secrethashed",
    )
    pet1 = PetDB(name="Nibbler", owner=user)

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,
)
```

#### 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"],

```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,
)
```

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

... was am Ende ergibt:

```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,
)
```
