## Import `Field`

First, you have to import it:

=== "Python 3.10+"

    ```Python hl_lines="4"
    {!> ../../../docs_src/body_fields/tutorial001_an_py310.py!}
    ```

=== "Python 3.9+"

    ```Python hl_lines="4"
    {!> ../../../docs_src/body_fields/tutorial001_an_py39.py!}
    ```

=== "Python 3.8+"

    ```Python hl_lines="4"
    {!> ../../../docs_src/body_fields/tutorial001_an.py!}
    ```

## 导入 `Field`

首先，从 Pydantic 中导入 `Field`：

=== "Python 3.10+"

    ```Python hl_lines="4"
    {!> ../../../docs_src/body_fields/tutorial001_an_py310.py!}
    ```

=== "Python 3.9+"

    ```Python hl_lines="4"
    {!> ../../../docs_src/body_fields/tutorial001_an_py39.py!}
    ```

=== "Python 3.8+"

    ```Python hl_lines="4"
    {!> ../../../docs_src/body_fields/tutorial001_an.py!}
    ```

=== "Python 3.9+"

    ```Python hl_lines="19"
    {!> ../../../docs_src/dependencies/tutorial006_an_py39.py!}
    ```

=== "Python 3.8+"

    ```Python hl_lines="18"
    {!> ../../../docs_src/dependencies/tutorial006_an.py!}
    ```

=== "Python 3.8 Annotated가 없는 경우"

    !!! tip "팁"
        가능하다면 `Annotated`가 달린 버전을 권장합니다.

    ```Python hl_lines="17"

=== "Python 3.10+"

    ```Python hl_lines="13  15  22  25"
    {!> ../../../docs_src/background_tasks/tutorial002_an_py310.py!}
    ```

=== "Python 3.9+"

    ```Python hl_lines="13  15  22  25"
    {!> ../../../docs_src/background_tasks/tutorial002_an_py39.py!}
    ```

=== "Python 3.8+"

    ```Python hl_lines="14  16  23  26"
    {!> ../../../docs_src/background_tasks/tutorial002_an.py!}

```

como em:

=== "Python 3.10+"

    ```Python hl_lines="15"
    {!> ../../../docs_src/body_multiple_params/tutorial005_py310.py!}
    ```

=== "Python 3.8+"

    ```Python hl_lines="17"
    {!> ../../../docs_src/body_multiple_params/tutorial005.py!}
    ```

Neste caso o **FastAPI** esperará um corpo como:

```JSON hl_lines="2"
{
    "item": {
        "name": "Foo",

Vous devez vous assurer qu'il est unique pour chaque opération.

```Python hl_lines="6"
{!../../../docs_src/path_operation_advanced_configuration/tutorial001.py!}
```

### Utilisation du nom *path operation function* comme operationId

=== "Python 3.8 and above"

    ```Python hl_lines="9  11  16  22  24  29-30  33-35  40-41"
    {!> ../../../docs_src/extra_models/tutorial001.py!}
    ```

=== "Python 3.10 and above"

    ```Python hl_lines="7  9  14  20  22  27-28  31-33  38-39"
    {!> ../../../docs_src/extra_models/tutorial001_py310.py!}
    ```
