Параметри функції будуть розпізнаватися наступним чином:

* Якщо параметр також оголошено в **шляху**, він використовуватиметься як параметр шляху.
* Якщо параметр має **сингулярний тип** (наприклад, `int`, `float`, `str`, `bool` тощо), він буде інтерпретуватися як параметр **запиту**.
* Якщо параметр оголошується як тип **Pydantic моделі**, він інтерпретується як **тіло** запиту.

O Python possui suporte para "dicas de tipo" ou "type hints" (também chamado de "anotações de tipo" ou "type annotations")

Esses **"type hints"** são uma sintaxe especial que permite declarar o <abbr title = "por exemplo: str, int, float, bool">tipo</abbr> de uma variável.

Ao declarar tipos para suas variáveis, editores e ferramentas podem oferecer um melhor suporte.

# 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.
