### 更主流的 Python

全部都基于标准的 **Python 3.6 类型**声明（感谢 Pydantic ）。没有新的语法需要学习。只需要标准的 Python 。

如果你需要2分钟来学习如何使用 Python 类型（即使你不使用 FastAPI ），看看这个简短的教程：[Python Types](python-types.md){.internal-link target=_blank}。

编写带有类型标注的标准 Python：

     * checked for emptiness is subject to change. We currently check {@code CharSequence}s, {@code
     * Collection}s, {@code Map}s, optionals (including Guava's), and arrays.
