```

A one będą mogły zostać później użyte w następujący sposób:

```Python
my_user: User = User(id=3, name="John Doe", joined="2018-07-19")

second_user_data = {
    "id": 4,
    "name": "Mary",
    "joined": "2018-11-30",
}

my_second_user: User = User(**second_user_data)
```

def main(user_id: str):
    return user_id


# Модель Pydantic
class User(BaseModel):
    id: int
    name: str
    joined: date
```

Это можно использовать так:

```Python
my_user: User = User(id=3, name="John Doe", joined="2018-07-19")

second_user_data = {
    "id": 4,
    "name": "Mary",
    "joined": "2018-11-30",
}

my_second_user: User = User(**second_user_data)
```

def main(user_id: str):
    return user_id


# Pydantic 모델
class User(BaseModel):
    id: int
    name: str
    joined: date
```

위의 코드는 다음과 같이 사용될 수 있습니다:

```Python
my_user: User = User(id=3, name="John Doe", joined="2018-07-19")

second_user_data = {
    "id": 4,
    "name": "Mary",
    "joined": "2018-11-30",
}

my_second_user: User = User(**second_user_data)
```

Daha yeni başladık ama çalışma mantığını çoktan anlamış oldunuz.

Şimdi aşağıdaki satırı değiştirmeyi deneyin:

```Python
    return {"item_name": item.name, "item_id": item_id}
```

...bundan:

```Python
        ... "item_name": item.name ...
```

...buna:

```Python
        ... "item_price": item.price ...
```

---

Ми лише трішки доторкнулися до коду, але Ви вже маєте уявлення про те, як все працює.

Спробуйте змінити рядок:

```Python
    return {"item_name": item.name, "item_id": item_id}
```

...із:

```Python
        ... "item_name": item.name ...
```

...на:

```Python
        ... "item_price": item.price ...
```

And the spec says that the fields have to be named like that. So `user-name` or `email` wouldn't work.

But don't worry, you can show it as you wish to your final users in the frontend.

And your database models can use any other names you want.
