Na pesquisa de desenvolvedores Python, ficou claro [que um dos recursos mais utilizados é o "preenchimento automático"](https://www.jetbrains.com/research/python-developers-survey-2017/#tools-and-features).

Todo o framework **FastAPI** é feito para satisfazer isso. O preenchimento automático funciona em todos os lugares.

import org.gradle.api.artifacts.type.ArtifactTypeDefinition;
import org.gradle.api.attributes.Attribute;
import org.gradle.api.internal.artifacts.ArtifactAttributes;
import org.jetbrains.annotations.NotNull;

import java.util.Arrays;

public class JdkDownloadPlugin implements Plugin<Project> {

    public static final String VENDOR_ADOPTIUM = "adoptium";

En las encuestas a desarrolladores de Python, es claro [que una de las funcionalidades más usadas es el "autocompletado"](https://www.jetbrains.com/research/python-developers-survey-2017/#tools-and-features).

Todo el framework **FastAPI** está basado para satisfacer eso. El autocompletado funciona en todas partes.

Rara vez necesitarás regresar a la documentación.

하지만 똑같은 편집기 지원을 [PyCharm](https://www.jetbrains.com/pycharm/)와 대부분의 다른 파이썬 편집기에서도 받을 수 있습니다:

만약 [PyCharm](https://www.jetbrains.com/pycharm/)를 편집기로 사용한다면, [Pydantic PyCharm Plugin](https://github.com/koxudaxi/pydantic-pycharm-plugin/)을 사용할 수 있습니다.

## 設計 { #design }

接著，我花時間設計作為使用者（作為使用 FastAPI 的開發者）時希望擁有的開發者「API」。

我在最受歡迎的 Python 編輯器中測試了多個想法：PyCharm、VS Code、基於 Jedi 的編輯器。

根據最新的 [Python 開發者調查](https://www.jetbrains.com/research/python-developers-survey-2018/#development-tools)，這些工具涵蓋約 80% 的使用者。

這表示 **FastAPI** 已針對 80% 的 Python 開發者所使用的編輯器進行過專門測試。而由於其他多數編輯器的行為也類似，這些優點擴及實際上幾乎所有編輯器。

藉此我找到了盡可能減少程式碼重複、在各處提供自動補全、型別與錯誤檢查等的最佳方式。

Probé varias ideas en los editores de Python más populares: PyCharm, VS Code, editores basados en Jedi.

Según la última [Encuesta de Desarrolladores de Python](https://www.jetbrains.com/research/python-developers-survey-2018/#development-tools), estos editores cubren alrededor del 80% de los usuarios.
