## Создание `main.py`

Скопируйте пример в файл `main.py`:

//// tab | Python 3.9+

```Python
{!> ../../docs_src/security/tutorial001_an_py39.py!}
```

////

//// tab | Python 3.8+

```Python
{!> ../../docs_src/security/tutorial001_an.py!}
```

////

//// tab | Python 3.8+ без Annotated

/// tip | "Подсказка"

Dit betekent ook dat je in Python 3.10 `EenType | None` kunt gebruiken:

//// tab | Python 3.10+

```Python hl_lines="1"
{!> ../../docs_src/python_types/tutorial009_py310.py!}
```

////

//// tab | Python 3.8+

```Python hl_lines="1  4"
{!> ../../docs_src/python_types/tutorial009.py!}
```

////

//// tab | Python 3.8+ alternative

```Python hl_lines="1  4"

## 🖼

📥 🖼 *➡ 🛠️* ⏮️ 🔢 ⚙️ 🔛 🆎.

//// tab | 🐍 3️⃣.6️⃣ & 🔛

```Python hl_lines="1  3  12-16"
{!> ../../docs_src/extra_data_types/tutorial001.py!}
```

////

//// tab | 🐍 3️⃣.1️⃣0️⃣ & 🔛

```Python hl_lines="1  2  11-15"
{!> ../../docs_src/extra_data_types/tutorial001_py310.py!}
```

////

В этом случае они будут применяться ко всем *операциям пути* в приложении:

//// tab | Python 3.9+

```Python hl_lines="16"
{!> ../../docs_src/dependencies/tutorial012_an_py39.py!}
```

////

//// tab | Python 3.8+

```Python hl_lines="16"
{!> ../../docs_src/dependencies/tutorial012_an.py!}
```

////

//// tab | Python 3.8 non-Annotated

/// tip | "Подсказка"

Điều này cũng có nghĩa là trong Python 3.10, bạn có thể sử dụng `Something | None`:

//// tab | Python 3.10+

```Python hl_lines="1"
{!> ../../docs_src/python_types/tutorial009_py310.py!}
```

////

//// tab | Python 3.8+

```Python hl_lines="1  4"
{!> ../../docs_src/python_types/tutorial009.py!}
```

////

//// tab | Python 3.8+ alternative

```Python hl_lines="1  4"

Nesse caso, elas serão aplicadas a todas as *operações de rota* da aplicação:

//// tab | Python 3.9+

```Python hl_lines="16"
{!> ../../docs_src/dependencies/tutorial012_an_py39.py!}
```

////

//// tab | Python 3.8+

```Python hl_lines="16"
{!> ../../docs_src/dependencies/tutorial012_an.py!}
```

////

//// tab | Python 3.8 non-Annotated

/// tip | "Dica"

//// tab | Python 3.10+

```Python hl_lines="22-27"
{!> ../../docs_src/schema_extra_example/tutorial003_an_py310.py!}
```

////

//// tab | Python 3.9+

```Python hl_lines="22-27"
{!> ../../docs_src/schema_extra_example/tutorial003_an_py39.py!}
```

////

//// tab | Python 3.8+

```Python hl_lines="23-28"

from fastapi import FastAPI

app = FastAPI()


@app.get("/items/", openapi_extra={"x-aperture-labs-portal": "blue"})
async def read_items():

Wenn Sie jedoch dasselbe Modell als Ausgabe verwenden, wie hier:

//// tab | Python 3.10+

```Python hl_lines="19"
{!> ../../docs_src/separate_openapi_schemas/tutorial001_py310.py!}
```

////

//// tab | Python 3.9+

```Python hl_lines="21"
{!> ../../docs_src/separate_openapi_schemas/tutorial001_py39.py!}
```

//// tab | Python 3.8+
