# Python 类型提示简介 { #python-types-intro }

Python 支持可选的“类型提示”（也叫“类型注解”）。

这些“类型提示”或注解是一种特殊语法，用来声明变量的<dfn title="例如：str、int、float、bool">类型</dfn>。

通过为变量声明类型，编辑器和工具可以为你提供更好的支持。

这只是一个关于 Python 类型提示的快速入门/复习。它只涵盖与 **FastAPI** 一起使用所需的最少部分...实际上非常少。

**FastAPI** 完全基于这些类型提示构建，它们带来了许多优势和好处。

但即使你从不使用 **FastAPI**，了解一些类型提示也会让你受益。

/// note | 注意

如果你已经是 Python 专家，并且对类型提示了如指掌，可以跳到下一章。

## 动机 { #motivation }

The function parameters will be recognized as follows:

* If the parameter is also declared in the **path**, it will be used as a path parameter.
* If the parameter is of a **singular type** (like `int`, `float`, `str`, `bool`, etc) it will be interpreted as a **query** parameter.
* If the parameter is declared to be of the type of a **Pydantic model**, it will be interpreted as a request **body**.
