`Optional[EenType]` is eigenlijk een snelkoppeling voor `Union[EenType, None]`, ze zijn equivalent.

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!}

`Optional[Something]` es realmente un atajo para `Union[Something, None]`, son equivalentes.

Esto también significa que en Python 3.10, puedes usar `Something | None`:

//// tab | Python 3.10+

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

استفاده از `Optional[str]` به جای فقط `str` به ویرایشگر کمک می‌کنه خطاهایی که ممکنه فکر کنی یه مقدار همیشه `str` هست رو پیدا کنه، در حالی که می‌تونه `None` هم باشه.

`Optional[Something]` در واقع میان‌بر برای `Union[Something, None]` هست، این دو تا معادلن.

یعنی توی پایتون 3.10، می‌تونی از `Something | None` استفاده کنی:

//// tab | Python 3.10+

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