Par exemple, vous pourriez déclarer que quelque chose peut être un `str` ou `None` :

```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]`
