这并非偶然，整个 **FastAPI** 框架都是围绕这种思路精心设计的。

并且，在 FastAPI 的设计阶段，我们就已经进行了全面测试，以确保 FastAPI 可以获得所有编辑器的支持。

我们还改进了 Pydantic，让它也支持这些功能。

虽然上面的截图取自 <a href="https://code.visualstudio.com" class="external-link" target="_blank">Visual Studio Code</a>。

但 <a href="https://www.jetbrains.com/pycharm/" class="external-link" target="_blank">PyCharm</a> 和大多数 Python 编辑器也支持同样的功能：

Houveram mudanças no próprio Pydantic para que isso fosse possível.

As capturas de tela anteriores foram capturas no <a href="https://code.visualstudio.com" class="external-link" target="_blank">Visual Studio Code</a>.

Mas você terá o mesmo suporte do editor no <a href="https://www.jetbrains.com/pycharm/" class="external-link" target="_blank">PyCharm</a> e na maioria dos editores Python:

    assertEquals(incrementByNanos * numberOfThreads, ticker.read());
