 * CompactHashSet is an implementation of a Set. All optional operations (adding and removing) are
 * supported. The elements can be any objects.
 *
 * <p>{@code contains(x)}, {@code add(x)} and {@code remove(x)}, are all (expected and amortized)

The `HeroUpdate` *data model* is somewhat special, it has **all the same fields** that would be needed to create a new hero, but all the fields are **optional** (they all have a default value). This way, when you update a hero, you can send just the fields that you want to update.

    * Add support for type annotations using `Optional` as in `param: Optional[str] = None`. New documentation: [Optional type declarations](https://fastapi.tiangolo.com/tutorial/query-params/#optional-type-declarations).
    * PR [#278](https://github.com/tiangolo/fastapi/pull/278).

## 0.26.0 (2019-05-29)

* `limit=10`: weil das der Defaultwert ist

## Optionale Parameter { #optional-parameters }

Auf die gleiche Weise können Sie optionale Query-Parameter deklarieren, indem Sie deren Defaultwert auf `None` setzen:

{* ../../docs_src/query_params/tutorial002_py310.py hl[7] *}

In diesem Fall wird der Funktionsparameter `q` optional und standardmäßig `None` sein.

# Using cgo directly

Usage:

	go tool cgo [cgo options] [-- compiler options] gofiles...

Cgo transforms the specified input Go source files into several output
Go and C source files.

The compiler options are passed through uninterpreted when
invoking the C compiler to compile the C parts of the package.

The following options are available when running cgo directly:

	-V

```python
from typing import Optional


def say_hi(name: Optional[str]):
    print(f"Hey {name}!")
```

`name` parametresi `Optional[str]` olarak tanımlıdır; ancak isteğe bağlı değildir, parametre olmadan fonksiyonu çağıramazsınız:

```Python
say_hi()  # Ah hayır, bu hata fırlatır! 😱
```

    };

    var elements = {};

    var phaseOrder = ['intent', 'search', 'evaluate', 'fetch', 'answer'];

    /**
     * Initialize the chat module
     */
    function init(options) {
        $.extend(true, config, options);

        elements = {
            chatMessages: $('#chatMessages'),
            chatInput: $('#chatInput'),
            sendBtn: $('#sendBtn'),
            newChatBtn: $('#newChatBtn'),

```

У `typing` також є скорочення, щоб оголосити, що щось може бути `None`, - `Optional`.

Ось порада з моєї дуже «суб'єктивної» точки зору:

- 🚨 Уникайте використання `Optional[SomeType]`
- Натомість ✨ **використовуйте `Union[SomeType, None]`** ✨.
