Na pesquisa de desenvolvedores Python, ficou claro <a href="https://www.jetbrains.com/research/python-developers-survey-2017/#tools-and-features" class="external-link" target="_blank">que um dos recursos mais utilizados é o "preenchimento automático"</a>.

하지만 똑같은 편집기 지원을 <a href="https://www.jetbrains.com/pycharm/" class="external-link" target="_blank">PyCharm</a>에서 받을 수 있거나, 대부분의 다른 편집기에서도 받을 수 있습니다:

En las encuestas a desarrolladores de Python, es claro <a href="https://www.jetbrains.com/research/python-developers-survey-2017/#tools-and-features" class="external-link" target="_blank">que una de las funcionalidades más usadas es el "autocompletado"</a>.

### 多種編輯器支援

整個框架的設計是為了讓使用變得簡單且直觀，在開始開發之前，所有決策都在多個編輯器上進行了測試，以確保提供最佳的開發體驗。

在最近的 Python 開發者調查中，我們能看到<a href="https://www.jetbrains.com/research/python-developers-survey-2017/#tools-and-features" class="external-link" target="_blank"> 被使用最多的功能是 autocompletion</a>，此功能可以預測將要輸入文字，並自動補齊。

整個 **FastAPI** 框架就是基於這一點，任何地方都可以進行自動補齊。

你幾乎不需要經常來回看文件。

  * When annotating existing internal code, use `org.jetbrains.annotations.Contract`, e.g. `@Contract(null -> null; !null -> !null)`.
      When doing so, still annotate nullable parameters and the return type as `@Nullable`.
  * Do not use `@Contract` for public APIs.

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

Según la última <a href="https://www.jetbrains.com/research/python-developers-survey-2018/#development-tools" class="external-link" target="_blank">Encuesta de Desarrolladores de Python</a>, estos editores cubren alrededor del 80% de los usuarios.

I tested several ideas in the most popular Python editors: PyCharm, VS Code, Jedi based editors.

By the last <a href="https://www.jetbrains.com/research/python-developers-survey-2018/#development-tools" class="external-link" target="_blank">Python Developer Survey</a>, that covers about 80% of the users.

しかし、<a href="https://www.jetbrains.com/pycharm/" class="external-link" target="_blank">PyCharm</a>やほとんどのPythonエディタでも同様なエディターサポートを受けられます:
