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:

[[es-release-notes]]
= Release notes

[partintro]
--

This section summarizes the changes in each release.

<% versions.each { print "* <<release-notes-${ it }>>\n" } %>
--

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]`

	}

	if _, ok := records[0]["@id"]; ok && fmt.Sprint(res2["id"]) != fmt.Sprint(records[0]["@id"]) {
		t.Errorf("failed to create data from map with table, @id != id, got %v, expect %v", res2["id"], records[0]["@id"])
	}

	if _, ok := records[1]["id"]; ok && fmt.Sprint(res3["id"]) != fmt.Sprint(records[1]["@id"]) {
		t.Errorf("failed to create data from map with table, @id != id")
	}

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

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 :

@app.exception_handler(StarletteHTTPException)
async def custom_http_exception_handler(request, exc):
    print(f"OMG! An HTTP error!: {repr(exc)}")
    return await http_exception_handler(request, exc)


@app.exception_handler(RequestValidationError)
async def validation_exception_handler(request, exc):
    print(f"OMG! The client sent invalid data!: {exc}")
    return await request_validation_exception_handler(request, exc)
