## 导入 Pydantic 的 `BaseModel` { #import-pydantics-basemodel }

从 `pydantic` 中导入 `BaseModel`：

{* ../../docs_src/body/tutorial001_py310.py hl[2] *}

## 创建数据模型 { #create-your-data-model }

把数据模型声明为继承 `BaseModel` 的类。

使用 Python 标准类型声明所有属性：

{* ../../docs_src/body/tutorial001_py310.py hl[5:9] *}

여러분은 타입이 있는 표준 Python을 다음과 같이 작성합니다:

```Python
from datetime import date

from pydantic import BaseModel

# 변수를 str로 선언합니다
# 그리고 함수 내부에서 편집기 지원을 받습니다
def main(user_id: str):
    return user_id


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

그 다음 다음과 같이 사용할 수 있습니다:

```Python

from typing import Annotated, Any
from uuid import UUID

from annotated_doc import Doc
from fastapi.exceptions import PydanticV1NotSupportedError
from fastapi.types import IncEx
from pydantic import BaseModel
from pydantic.color import Color  # ty: ignore[deprecated]
from pydantic.networks import AnyUrl, NameEmail
from pydantic.types import SecretBytes, SecretStr
from pydantic_core import PydanticUndefinedType

型を使った標準的な Python を記述します:

```Python
from datetime import date

from pydantic import BaseModel

# Declare a variable as a str
# and get editor support inside the function
def main(user_id: str):
    return user_id


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

これは次のように使えます:
