Zum Beispiel könnten Sie deklarieren, dass etwas ein `str` oder `None` sein könnte:

```python
from typing import Union


def say_hi(name: Union[str, None]):
        print(f"Hi {name}!")
```

`typing` hat außerdem eine Abkürzung, um zu deklarieren, dass etwas `None` sein könnte, mit `Optional`.

Hier ist ein Tipp aus meiner sehr **subjektiven** Perspektive:

Например, вы можете объявить, что значение может быть `str` или `None`:

```python
from typing import Union


def say_hi(name: Union[str, None]):
        print(f"Hi {name}!")
```

В `typing` также есть сокращение, чтобы объявить, что значение может быть `None`, — `Optional`.

Вот совет с моей очень субъективной точки зрения:

- 🚨 Избегайте использования `Optional[SomeType]`

```python
from typing import Union


def say_hi(name: Union[str, None]):
        print(f"Hi {name}!")
```

`typing` propose également un raccourci pour déclarer que quelque chose peut être `None`, avec `Optional`.

Voici un conseil issu de mon point de vue très subjectif :

- 🚨 Évitez d'utiliser `Optional[SomeType]`
- À la place ✨ **utilisez `Union[SomeType, None]`** ✨.
