#### `HeroBase` - a classe base

Vamos começar com um modelo `HeroBase` que tem todos os **campos compartilhados** por todos os modelos:

* `name`
* `age`

{* ../../docs_src/sql_databases/tutorial002_an_py310.py ln[7:9] hl[7:9] *}

#### `Hero` - o *modelo de tabela*

Maintenant que vous avez connaissance du problème, convertissez `age` en <abbr title="string">chaîne de caractères</abbr> grâce à `str(age)` :

{*../../docs_src/python_types/tutorial004.py hl[2] *}

## Déclarer des types

Vous venez de voir là où les types sont généralement déclarés : dans les paramètres de fonctions.

Because the editor knows the types of the variables, you don't only get completion, you also get error checks:

Now you know that you have to fix it, convert `age` to a string with `str(age)`:

{* ../../docs_src/python_types/tutorial004.py hl[2] *}

## Declaring types

You just saw the main place to declare type hints. As function parameters.

> **NOTE:** Do **NOT** run `gradle build` on the local development environment,

> The Gradle Build Tool repository is massive, and it will take ages to build on

> The full test suites are executed on the CI instance for multiple configurations,
