例如，您可以创建一个名为 `config.py` 的文件，其中包含以下内容：

```Python
{!../../docs_src/settings/app01/config.py!}
```

然后在一个名为 `main.py` 的文件中使用它：

```Python hl_lines="3  11-13"
{!../../docs_src/settings/app01/main.py!}
```

/// tip

```Python hl_lines="4  78"
{!> ../../docs_src/security/tutorial003_an_py310.py!}
```

////

//// tab | Python 3.9+

```Python hl_lines="4  78"
{!> ../../docs_src/security/tutorial003_an_py39.py!}
```

////

//// tab | Python 3.8+

```Python hl_lines="4  79"
{!> ../../docs_src/security/tutorial003_an.py!}
```

////

//// tab | Python 3.10+ non-Annotated

/// tip

```Python hl_lines="4  78"
{!> ../../docs_src/security/tutorial003_an_py310.py!}
```

////

//// tab | Python 3.9+

```Python hl_lines="4  78"
{!> ../../docs_src/security/tutorial003_an_py39.py!}
```

////

//// tab | Python 3.8+

```Python hl_lines="4  79"
{!> ../../docs_src/security/tutorial003_an.py!}
```

////

//// tab | Python 3.10+ nicht annotiert

/// tip | "Tipp"

Sie könnten beispielsweise eine Datei `config.py` haben mit:

```Python
{!../../docs_src/settings/app01/config.py!}
```

Und dann verwenden Sie diese in einer Datei `main.py`:

```Python hl_lines="3  11-13"
{!../../docs_src/settings/app01/main.py!}
```

/// tip | "Tipp"

```
.
├── app
│   ├── __init__.py
│   ├── main.py
│   └── test_main.py
```

Die Datei `main.py` hätte als Inhalt:

```Python
{!../../docs_src/async_tests/main.py!}
```

Die Datei `test_main.py` hätte die Tests für `main.py`, das könnte jetzt so aussehen:

```Python
{!../../docs_src/async_tests/test_main.py!}
```

## Es ausführen

```
.
├── app
│   ├── __init__.py
│   ├── main.py
│   └── test_main.py
```

The file `main.py` would have:

{* ../../docs_src/async_tests/main.py *}

The file `test_main.py` would have the tests for `main.py`, it could look like this now:

{* ../../docs_src/async_tests/test_main.py *}

## Run it

You can run your tests as usual via:

<div class="termy">

{!> ../../docs_src/dependencies/tutorial006_an_py39.py!}
```

```Python hl_lines="18"

////

//// tab | Python 3.8 non-Annotated

/// tip | "Dica"

Utilize a versão com `Annotated` se possível

```

////

//// tab | Python 3.8+

```Python hl_lines="18  23"

```

FastAPI will use this return type to:

{!../../docs_src/dependencies/tutorial007.py!}
```

The yielded value is what is injected into *path operations* and other dependencies:

```Python hl_lines="4"
{!../../docs_src/dependencies/tutorial007.py!}
```

The code following the `yield` statement is executed after the response has been delivered:

```Python hl_lines="5-6"
{!../../docs_src/dependencies/tutorial007.py!}
```

/// tip

{!> ../../docs_src/dependencies/tutorial006_an_py39.py!}
```

////

//// tab | Python 3.8+

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

////

//// tab | Python 3.8 Annotated가 없는 경우

/// tip | "팁"

가능하다면 `Annotated`가 달린 버전을 권장합니다.
