Es gab sogar ein paar Änderungen an Pydantic selbst, um das zu unterstützen.

Die vorherigen Screenshots zeigten <a href="https://code.visualstudio.com" class="external-link" target="_blank">Visual Studio Code</a>.

Aber Sie bekommen die gleiche Editor-Unterstützung in <a href="https://www.jetbrains.com/pycharm/" class="external-link" target="_blank">PyCharm</a> und in den meisten anderen Python-Editoren:

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：

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:
