    "id": 4,
    "name": "Mary",
    "joined": "2018-11-30",

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

!!! info
    `**second_user_data` یعنی:

    کلید ها و مقادیر دیکشنری `second_user_data` را مستقیما به عنوان ارگومان های key-value بفرست، که معادل است با : `User(id=4, name="Mary", joined="2018-11-30")`

👥 🔜 ⚙️ `Session` (1️⃣ 🗄 ⚪️➡️ 🇸🇲) ⏪.

✍ `SessionLocal` 🎓, ⚙️ 🔢 `sessionmaker`:

Dazu deklarieren wir eine Methode `__call__`:

=== "Python 3.9+"

    ```Python hl_lines="12"
    {!> ../../../docs_src/dependencies/tutorial011_an_py39.py!}
    ```

=== "Python 3.8+"

    ```Python hl_lines="11"
    {!> ../../../docs_src/dependencies/tutorial011_an.py!}
    ```

=== "Python 3.8+ nicht annotiert"

    !!! tip "Tipp"
        Bevorzugen Sie die `Annotated`-Version, falls möglich.

    {!> ../../../docs_src/dependencies/tutorial005_an.py!}
    ```

=== "Python 3.10 non-Annotated"

    !!! tip
        Prefer to use the `Annotated` version if possible.

    ```Python hl_lines="11"
    {!> ../../../docs_src/dependencies/tutorial005_py310.py!}
    ```

=== "Python 3.8 non-Annotated"

    !!! tip
        Prefer to use the `Annotated` version if possible.

    ```Python hl_lines="13"

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

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

!!! info "정보"
    `**second_user_data`가 뜻하는 것:

    `second_user_data` 딕셔너리의 키와 값을 키-값 인자로서 바로 넘겨줍니다. 다음과 동일합니다: `User(id=4, name="Mary", joined="2018-11-30")`

### 편집기 지원

모든 프레임워크는 사용하기 쉽고 직관적으로 설계되었으며, 좋은 개발 경험을 보장하기 위해 개발을 시작하기도 전에 모든 결정들은 여러 편집기에서 테스트됩니다.

# (8)
COPY --from=requirements-stage /tmp/requirements.txt /code/requirements.txt

# (9)
RUN pip install --no-cache-dir --upgrade -r /code/requirements.txt

# (10)
COPY ./app /code/app

# (11)
CMD ["uvicorn", "app.main:app", "--host", "0.0.0.0", "--port", "80"]
```

1. 첫 스테이지로, `requirements-stage`라고 이름 붙였습니다.

2. `/tmp`를 현재의 워킹 디렉터리로 설정합니다.

    이 위치에 우리는 `requirements.txt` 파일을 생성할 것입니다.

*경로 작동 함수*가 가질 수 있는 모든 매개변수를 갖는 단순한 함수입니다:

=== "Python 3.10+"

    ```Python hl_lines="8-9"
    {!> ../../../docs_src/dependencies/tutorial001_an_py310.py!}
    ```

=== "Python 3.9+"

    ```Python hl_lines="8-11"
    {!> ../../../docs_src/dependencies/tutorial001_an_py39.py!}
    ```

=== "Python 3.8+"

    ```Python hl_lines="9-12"
    {!> ../../../docs_src/dependencies/tutorial001_an.py!}
    ```

Tudo isso, aninhado arbitrariamente.

### Defina um sub-modelo

Por exemplo, nós podemos definir um modelo `Image`:

```Python hl_lines="9-11"
{!../../../docs_src/body_nested_models/tutorial004.py!}
```

### Use o sub-modelo como um tipo

E então podemos usa-lo como o tipo de um atributo:

```Python hl_lines="20"

=== "🐍 3️⃣.6️⃣ & 🔛"

    ```Python hl_lines="13"
    {!> ../../../docs_src/dependencies/tutorial005.py!}
    ```

=== "🐍 3️⃣.1️⃣0️⃣ & 🔛"

    ```Python hl_lines="11"
    {!> ../../../docs_src/dependencies/tutorial005_py310.py!}
    ```
