# Python Types Intro { #python-types-intro }

Python has support for optional "type hints" (also called "type annotations").

These **"type hints"** or annotations are a special syntax that allow declaring the <abbr title="for example: str, int, float, bool">type</abbr> of a variable.

By declaring types for your variables, editors and tools can give you better support.

# Вступ до типів Python

Python підтримує додаткові "підказки типу" ("type hints") (також звані "анотаціями типу" ("type annotations")).

Ці **"type hints"** є спеціальним синтаксисом, що дозволяє оголошувати <abbr title="наприклад: str, int, float, bool">тип</abbr> змінної.

За допомогою оголошення типів для ваших змінних, редактори та інструменти можуть надати вам кращу підтримку.
