# Introduction aux Types Python

Python supporte des annotations de type (ou *type hints*) optionnelles.

Ces annotations de type constituent une syntaxe spéciale qui permet de déclarer le <abbr title="par exemple : str, int, float, bool">type</abbr> d'une variable.

En déclarant les types de vos variables, cela permet aux différents outils comme les éditeurs de texte d'offrir un meilleur support.

   * list to {@link com.google.common.collect.ImmutableList#copyOf(Collection) ImmutableList.copyOf}
   * and use that list instead.
   */
  public List<Long> asList() {
    /*
     * Typically we cache this kind of thing, but much repeated use of this view is a performance
     * anti-pattern anyway. If we cache, then everyone pays a price in memory footprint even if
     * they never use this method.
     */
    return new AsList(this);

   * ImmutableList.copyOf} and use that list instead.
   */
  public List<Integer> asList() {
    /*
     * Typically we cache this kind of thing, but much repeated use of this view is a performance
     * anti-pattern anyway. If we cache, then everyone pays a price in memory footprint even if
     * they never use this method.
     */
    return new AsList(this);

It streamlines the process of **building**, **deploying**, and **accessing** an API with minimal effort.

It brings the same **developer experience** of building apps with FastAPI to **deploying** them to the cloud. 🎉

FastAPI Cloud is the primary sponsor and funding provider for the *FastAPI and friends* open source projects. ✨

    client.processNextFrame()
    taskFaker.runTasks()
    server.webSocket!!.pong("pong 3".encodeUtf8())
    client.processNextFrame()

    // After 500ms the client automatically pings and the server pongs back.
    taskFaker.advanceUntil(ns(500L))
    server.processNextFrame() // Ping.
    client.processNextFrame() // Pong.

## Використання `Annotated` у типі параметра `q`

Пам’ятаєте, як я раніше розповідав, що `Annotated` можна використовувати для додавання метаданих до параметрів у [Вступі до типів Python](../python-types.md#type-hints-with-metadata-annotations){.internal-link target=_blank}?

Зараз саме час використати його разом із FastAPI. 🚀

Раніше ми мали таку анотацію типу:

//// tab | Python 3.10+

```Python
q: str | None = None

{* ../../docs_src/dependencies/tutorial007_py39.py hl[5:6] *}

/// tip

You can use `async` or regular functions.

**FastAPI** will do the right thing with each, the same as with normal dependencies.

///

## A dependency with `yield` and `try` { #a-dependency-with-yield-and-try }

    int removes = frequency(asList(stimuli), remove);
    if ((!features.contains(IteratorFeature.SUPPORTS_REMOVE) && removes > 1)
        || (stimuli.length >= 5 && removes > 2)) {
      // removes are the most expensive thing to test, since they often throw exceptions with stack
      // traces, so we test them a bit less aggressively
      return;
    }

# 파이썬 타입 소개

파이썬은 선택적으로 "타입 힌트(type hints)"를 지원합니다.

이러한 **타입 힌트**들은 변수의 <abbr title="예를 들면: str, int, float, bool">타입</abbr>을 선언할 수 있게 해주는 특수한 구문입니다.

변수의 타입을 지정하면 에디터와 툴이 더 많은 도움을 줄 수 있게 됩니다.

이 문서는 파이썬 타입 힌트에 대한 **빠른 자습서 / 내용환기** 수준의 문서입니다. 여기서는 **FastAPI**를 쓰기 위한 최소한의 내용만을 다룹니다.

**FastAPI**는 타입 힌트에 기반을 두고 있으며, 이는 많은 장점과 이익이 있습니다.

비록 **FastAPI**를 쓰지 않는다고 하더라도, 조금이라도 알아두면 도움이 될 것입니다.
