#### 解包 `dict` 和更多关键字

接下来，继续添加关键字参数 `hashed_password=hashed_password`，例如：

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

……输出结果如下：

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

!!! warning "警告"

				</div>
				<la:form styleId="updatePassword" method="post">
					<div class="input-group mb-3">
						<c:set var="ph_old_password">
							<la:message key="labels.profile.placeholder_old_password" />
						</c:set>
						<la:password property="oldPassword" class="form-control"
									 placeholder="${ph_old_password}" />
						<div class="input-group-append">
							<span class="input-group-text"><em class="fa fa-lock fa-fw"></span>

```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,
)
```
