Użycie w Twoim edytorze jest tym, co pokazuje prawdziwe korzyści z FastAPI, pozwala zobaczyć jak mało kodu musisz napisać, wszystkie funkcje, takie jak kontrola typów, <abbr title="auto-complete, autocompletion, IntelliSense">automatyczne uzupełnianie</abbr>, itd.

## Instalacja FastAPI

Jako pierwszy krok zainstaluj FastAPI.

Na potrzeby samouczka możesz zainstalować również wszystkie opcjonalne biblioteki:

        def step1 = PatternStepFactory.getStep("*abc", true);
        step1 instanceof HasSuffixPatternStep
        step1.suffix == "abc"

        step1.matches("abc")
        step1.matches("thing.abc")
        !step1.matches("thing.java")

        and:
        def step2 = PatternStepFactory.getStep("**abc", true);
        step2 instanceof HasSuffixPatternStep
        step2.suffix == "abc"

        step2.matches("abc")

`summary`と`description`を追加できます:

```Python hl_lines="20-21"
{!../../../docs_src/path_operation_configuration/tutorial003.py!}
```

## docstringを用いた説明

説明文は長くて複数行におよぶ傾向があるので、関数<abbr title="ドキュメントに使用される関数内の最初の式（変数に代入されていない）としての複数行の文字列">docstring</abbr>内に*path operation*の説明文を宣言できます。すると、**FastAPI** は説明文を読み込んでくれます。

* Das **herausgehende Modell** sollte kein Passwort haben.
* Das **Datenbankmodell** sollte wahrscheinlich ein <abbr title='Ein aus scheinbar zufälligen Zeichen bestehender „Fingerabdruck“ eines Textes. Der Inhalt des Textes kann nicht eingesehen werden.'>gehashtes</abbr> Passwort haben.

## 숫자 검증: 부동소수, 크거나 및 작거나

숫자 검증은 `float` 값에도 동작합니다.

여기에서 <abbr title="greater than or equal"><code>ge</code></abbr>뿐만 아니라 <abbr title="greater than"><code>gt</code></abbr>를 선언 할 수있는 것이 중요해집니다. 예를 들어 필요한 경우, 값이 `1`보다 작더라도 반드시 `0`보다 커야합니다.

즉, `0.5`는 유효한 값입니다. 그러나 `0.0` 또는 `0`은 그렇지 않습니다.

<abbr title="less than"><code>lt</code></abbr> 역시 마찬가지입니다.

```Python hl_lines="11"

```

In this case, `item_id` is declared to be an `int`.

!!! check
    This will give you editor support inside of your function, with error checks, completion, etc.
