### 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。

在這裡，你的編輯器可能會這樣幫助你：
