In Python 3.10 there's also a **new syntax** where you can put the possible types separated by a <abbr title='also called "bitwise or operator", but that meaning is not relevant here'>vertical bar (`|`)</abbr>.

Trong Python 3.10 cũng có một **cú pháp mới** mà bạn có thể đặt những kiểu giá trị khả thi phân cách bởi một dấu <abbr title='cũng được gọi là "toán tử nhị phân"'>sổ dọc (`|`)</abbr>.

    * This SNI extension allows one single server (with a **single IP address**) to have **several HTTPS certificates** and serve **multiple HTTPS domains/applications**.

# Python Veri Tiplerine Giriş

Python isteğe bağlı olarak "tip belirteçlerini" destekler.

 **"Tip belirteçleri"** bir değişkenin <abbr title="örneğin: str, int, float, bool">tipinin</abbr> belirtilmesine olanak sağlayan özel bir sözdizimidir.

Değişkenlerin tiplerini belirterek editör ve araçlardan daha fazla destek alabilirsiniz.

Por defecto, esos archivos se sirven desde un <abbr title="Content Delivery Network: Un servicio, normalmente compuesto de varios servidores, que proporciona archivos estáticos, como JavaScript y CSS. Se utiliza comúnmente para servir esos archivos desde el servidor más cercano al cliente, mejorando el rendimiento.">CDN</abbr>.

    * Cette extension SNI permet à un seul serveur (avec une seule adresse IP) d'avoir plusieurs certificats HTTPS et de servir plusieurs domaines/applications HTTPS.

## Альтернативный (устаревший) способ задать `Query` как значение по умолчанию

В предыдущих версиях FastAPI (ниже <abbr title="ранее 2023-03">0.95.0</abbr>) необходимо было использовать `Query` как значение по умолчанию для query-параметра. Так было вместо размещения его в `Annotated`, так что велика вероятность, что вам встретится такой код. Сейчас объясню.

It was created to generate the HTML in the backend, not to create APIs used by a modern frontend (like React, Vue.js and Angular) or by other systems (like <abbr title="Internet of Things">IoT</abbr> devices) communicating with it.
