```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]`** ✨.

```python
from typing import Union


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

`typing` also has a shortcut to declare that something could be `None`, with `Optional`.

Here's a tip from my very **subjective** point of view:

* 🚨 Avoid using `Optional[SomeType]`
* Instead ✨ **use `Union[SomeType, None]`** ✨.

// The logic to sort by last octet is implemented to
// prefer CIDRs with higher octets, this in-turn skips the
// localhost/loopback address to be not preferred as the
// first ip on the list. Subsequently this list helps us print
// a user friendly message with appropriate values.
func sortIPs(ipList []string) []string {
	if len(ipList) == 1 {
		return ipList
	}

	var ipV4s []net.IP
	var nonIPs []string

Par exemple, vous pouvez avoir un fichier `main.py` contenant :

```Python hl_lines="3"
import os

name = os.getenv("MY_NAME", "World")
print(f"Hello {name} from Python")
```

/// tip | Astuce

Le deuxième argument de [`os.getenv()`](https://docs.python.org/3.8/library/os.html#os.getenv) est la valeur par défaut à retourner.
