/// tip | Dica

Alguns editores de texto checam parâmetros de funções não utilizados, e os mostram como erros.

Utilizando `dependencies` no *decorador da operação de rota* você pode garantir que elas serão executadas enquanto evita erros de editores/ferramentas.

/// tip | Tipp

Wenn Sie in Ihrem Editor strikte Typchecks haben, mypy, usw., können Sie den Funktions-Rückgabetyp als <abbr title="„Irgend etwas“">`Any`</abbr> deklarieren.

Ve OpenAPI şemaları üretir.

Flask, Starlette, Responder vb. için çalışma şekli böyledir.

Ancak yine, Python metni içinde (kocaman bir YAML) mikro bir söz dizimi sorunu ortaya çıkar.

Editör bu konuda pek yardımcı olamaz. Parametreleri veya Marshmallow şemalarını değiştirip docstring’teki YAML’ı güncellemeyi unutursak, üretilen şema geçerliliğini yitirir.

/// info | Bilgi

        } else {
            // Direct version comparison and upgrade
            if (isVersionBelow(currentVersion, upgrade.minVersion)) {
                Editor editor = new Editor(pomDocument);
                editor.setTextContent(versionElement, upgrade.minVersion);
                context.detail("Upgraded " + upgrade.groupId + ":" + upgrade.artifactId + " from " + currentVersion

And it generates OpenAPI schemas.

That's how it works in Flask, Starlette, Responder, etc.

But then, we have again the problem of having a micro-syntax, inside of a Python string (a big YAML).

The editor can't help much with that. And if we modify parameters or Marshmallow schemas and forget to also modify that YAML docstring, the generated schema would be obsolete.

你幾乎不需要經常來回看文件。

在這裡，你的編輯器可能會這樣幫助你：

* 在 [Visual Studio Code](https://code.visualstudio.com/) 中:

* 在 [PyCharm](https://www.jetbrains.com/pycharm/) 中:

你將能進行程式碼補齊，這是在之前你可能曾認為不可能的事。例如，請求 JSON body（可能是巢狀的）中的鍵 `price`。

Es wird **dringend empfohlen**, den Code zu schreiben oder zu kopieren, ihn zu bearbeiten und lokal auszuführen.

Die Verwendung in Ihrem eigenen Editor zeigt Ihnen die Vorteile von FastAPI am besten, wenn Sie sehen, wie wenig Code Sie schreiben müssen, all die Typprüfungen, die automatische Vervollständigung usw.

## FastAPI installieren { #install-fastapi }

```

</div>

It is **HIGHLY encouraged** that you write or copy the code, edit it and run it locally.

Using it in your editor is what really shows you the benefits of FastAPI, seeing how little code you have to write, all the type checks, autocompletion, etc.

## Install FastAPI { #install-fastapi }

The first step is to install FastAPI.
