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

  ls=$(ls -ld "$SCRIPT")
  # Drop everything prior to ->
  link=$(expr "$ls" : '.*-> \(.*\)$')
  if expr "$link" : '/.*' > /dev/null; then
    SCRIPT="$link"
  else
    SCRIPT=$(dirname "$SCRIPT")/"$link"
  fi
done

if [ "$(uname -m)" = "arm64" ] || [ "$(uname -m)" = "aarch64" ]; then
  ## On ARM we use a different properties file for setting java home
  ## Also, we don't bother attempting to resolve dependencies for the 6.8 branch

   * that returns a {@code ClosingFuture} to its value. The function can use a {@link
   * DeferredCloser} to capture objects to be closed when the pipeline is done (other than those
   * captured by the returned {@link ClosingFuture}).
   *
   * <p>If this {@code ClosingFuture} succeeds, the derived one will be equivalent to the one
   * returned by the function.

### Değiştirerek güncelleme uyarısı { #warning-about-replacing }

Bu, `bar` öğesini `PUT` ile, body içinde şu verilerle güncellemek isterseniz:

```Python
{
    "name": "Barz",
    "price": 3,
    "description": None,
}
```

zaten kayıtlı olan `"tax": 20.2` alanını içermediği için, input model `"tax": 10.5` varsayılan değerini kullanacaktır.

Ve veri, bu "yeni" `tax` değeri olan `10.5` ile kaydedilecektir.

We had this type annotation:

```Python
q: str | None = None
```

What we will do is wrap that with `Annotated`, so it becomes:

```Python
q: Annotated[str | None] = None
```

Both of those versions mean the same thing, `q` is a parameter that can be a `str` or `None`, and by default, it is `None`.

Now let's jump to the fun stuff. 🎉

Response model’inizde şu şekilde default değerler olabilir:

{* ../../docs_src/response_model/tutorial004_py310.py hl[9,11:12] *}

* `description: Union[str, None] = None` (veya Python 3.10’da `str | None = None`) için default `None`’dır.
* `tax: float = 10.5` için default `10.5`’tir.
* `tags: List[str] = []` için default, boş bir list’tir: `[]`.

 *
 * All event methods must execute fast, without external locking, cannot throw exceptions,
 * attempt to mutate the event parameters, or be reentrant back into the client.
 * Any IO - writing to files or network should be done asynchronously.
