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]`

Örneğin, bir şeyin `str` ya da `None` olabileceğini şöyle belirtebilirsiniz:

```python
from typing import Union


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

`typing`, bir şeyin `None` olabileceğini belirtmek için `Optional` ile bir kısayol da sunar.

Benim oldukça öznel bakış açıma göre küçük bir ipucu:

- 🚨 `Optional[SomeType]` kullanmaktan kaçının

			if e != nil {
				return e
			}
			// Quote string...
			b, _ := json.Marshal(file.Name)
			if hasWritten {
				fmt.Print(",\n")
			}
			fmt.Printf("\t%s: ", string(b))

			b, e = decode(r, file.Name)
			if e != nil {
				return e
			}
			fmt.Print(string(b))
			hasWritten = true
		}
	}
	fmt.Println("")
	fmt.Println("}")

	return nil
}

var (

```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]`** ✨.
