上例中 ，从 `user_in.dict()` 中得到了 `user_dict`，下面的代码：

```Python
user_dict = user_in.dict()
UserInDB(**user_dict)
```

等效于：

```Python
UserInDB(**user_in.dict())
```

……因为 `user_in.dict()` 是字典，在传递给 `UserInDB` 时，把 `**` 加在  `user_in.dict()` 前，可以让 Python 进行**解包**。

这样，就可以用其它 Pydantic 模型中的数据生成 Pydantic 模型。

#### 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：

  // User is the user you're testing for.
  // If you specify "User" but not "Groups", then is it interpreted as "What if User were not a member of any groups
  // +optional
  optional string user = 3;

  // Groups is the groups you're testing for.
  // +optional
  repeated string groups = 4;

Da wir in obigem Beispiel `user_dict` mittels `user_in.dict()` erzeugt haben, ist dieser Code:

```Python
user_dict = user_in.dict()
UserInDB(**user_dict)
```

äquivalent zu:

```Python
UserInDB(**user_in.dict())
```

... weil `user_in.dict()` ein `dict` ist, und dann lassen wir Python es „entpacken“, indem wir es `UserInDB` übergeben, mit vorangestelltem `**`.

}

// UserInfo holds the information about the user needed to implement the
// user.Info interface.
message UserInfo {
  // The name that uniquely identifies this user among all active users.
  // +optional
  optional string username = 1;

  // A unique value that identifies this user across time. If this user is
  // deleted and another user by the same name is added, they will have
  // different UIDs.
