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) {
