注意，函数内的参数有原生的数据类型，你可以，例如，执行正常的日期操作，如:

=== "Python 3.10+"

    ```Python hl_lines="18-19"
    {!> ../../../docs_src/extra_data_types/tutorial001_an_py310.py!}
    ```

=== "Python 3.9+"

    ```Python hl_lines="18-19"
    {!> ../../../docs_src/extra_data_types/tutorial001_an_py39.py!}
    ```

=== "Python 3.8+"

    ```Python hl_lines="19-20"

    ```

Обратите внимание, что параметры внутри функции имеют свой естественный тип данных, и вы, например, можете выполнять обычные манипуляции с датами, такие как:

=== "Python 3.8 и выше"

    ```Python hl_lines="18-19"
    {!> ../../../docs_src/extra_data_types/tutorial001.py!}
    ```

=== "Python 3.10 и выше"

    ```Python hl_lines="17-18"
    {!> ../../../docs_src/extra_data_types/tutorial001_py310.py!}

{!../../../docs_src/extra_data_types/tutorial001.py!}
```

Note que os parâmetros dentro da função tem seu tipo de dados natural, e você pode, por exemplo, realizar manipulações normais de data, como:

```Python hl_lines="18-19"
{!../../../docs_src/extra_data_types/tutorial001.py!}

        in 13..14 -> {
          type = source.readUtf8LineStrict().takeIf { it.isNotEmpty() }
        }

        in 15..17 -> {
          type = null // 'event' on a line of its own
        }

        in 18..19 -> {
          val retryMs = source.readRetryMs()
          if (retryMs != -1L) {
            callback.onRetryChange(retryMs)
          }
        }

        -1 -> {

{!../../../docs_src/path_operation_configuration/tutorial002b.py!}
```

## Краткое и развёрнутое содержание

Вы можете добавить параметры `summary` и `description`:

=== "Python 3.10+"

    ```Python hl_lines="18-19"
    {!> ../../../docs_src/path_operation_configuration/tutorial003_py310.py!}
    ```

=== "Python 3.9+"

    ```Python hl_lines="20-21"
    {!> ../../../docs_src/path_operation_configuration/tutorial003_py39.py!}
