# Python Veri Tiplerine Giriş

Python isteğe bağlı olarak "tip belirteçlerini" destekler.

 **"Tip belirteçleri"** bir değişkenin <abbr title="örneğin: str, int, float, bool">tipinin</abbr> belirtilmesine olanak sağlayan özel bir sözdizimidir.

Değişkenlerin tiplerini belirterek editör ve araçlardan daha fazla destek alabilirsiniz.

# Introducción a los Tipos de Python

**Python 3.6+** tiene soporte para <abbr title="en español, anotaciones de tipo. En inglés también se conocen como: type annotations">"type hints"</abbr> opcionales.

Estos **type hints** son una nueva sintaxis, desde Python 3.6+, que permite declarar el <abbr title="por ejemplo: str, int, float, bool">tipo</abbr> de una variable.

# Python 类型提示简介

**Python 3.6+ 版本**加入了对"类型提示"的支持。

这些**"类型提示"**是一种新的语法（在 Python 3.6 版本加入）用来声明一个变量的<abbr title="例如：str、int、float、bool">类型</abbr>。

通过声明变量的类型，编辑器和一些工具能给你提供更好的支持。

这只是一个关于 Python 类型提示的**快速入门 / 复习**。它仅涵盖与 **FastAPI** 一起使用所需的最少部分...实际上只有很少一点。

整个 **FastAPI** 都基于这些类型提示构建，它们带来了许多优点和好处。

但即使你不会用到 **FastAPI**，了解一下类型提示也会让你从中受益。
