`str` yerine `Optional[str]` kullanmak editorün bu değerin her zaman `str` tipinde değil bazen `None` tipinde de olabileceğini belirtir ve hataları tespit etmemizde yardımcı olur.

#### Generic tipler

Köşeli parantez içinde tip parametreleri alan bu türler, örneğin:

* `List`
* `Tuple`
* `Set`
* `Dict`
* `Optional`
* ...and others.

Burada "yol" bağlantıda bulunan ilk `/` ile başlayan ve sonrasında gelen kısmı ifade eder.

Yani, şu şekilde bir bağlantıda:

```
https://example.com/items/foo
```

... yol şöyle olur:

```
/items/foo
```

/// info | "Bilgi"

"Yol" genellikle "<abbr title="Endpoint: Bitim Noktası">endpoint</abbr>" veya "<abbr title="Route: Yönlendirme/Yön">route</abbr>" olarak adlandırılır.

    * `name` adında məcburi bir parametr olub olmadığını və əgər varsa, tipinin `str` olub olmadığını yoxlayacaq.
    * `price` adında məcburi bir parametr olub olmadığını və əgər varsa, tipinin `float` olub olmadığını yoxlayacaq.
    * `is_offer` adında <abbr title="Məcburi olmayan: Optional">məcburi olmayan</abbr> bir parametr olub olmadığını və əgər varsa, tipinin `float` olub olmadığını yoxlayacaq.

Let's look at how we can make that work.

## pytest.mark.anyio

If we want to call asynchronous functions in our tests, our test functions have to be asynchronous. AnyIO provides a neat plugin for this, that allows us to specify that some test functions are to be called asynchronously.
