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

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

This is just a **quick tutorial / refresher** about Python type hints. It covers only the minimum necessary to use them with **FastAPI**... which is actually very little.

In order to run the YAML tests, the relevant API specification needs
to be on the test classpath. Any gradle project that has support for REST
tests will get the primary API on it's class path. However, to better support
Gradle incremental builds, it is recommended to explicitly declare which
parts of the API the tests depend upon.

For example:
---------------------------------------------------------------------------

        elements.sendBtn.on('click', sendMessage);

        elements.chatInput.on('keydown', function(e) {
            // Prevent sending during IME composition (Japanese, Chinese, etc.)
            if (e.key === 'Enter' && !e.shiftKey && !e.isComposing) {
                e.preventDefault();
                sendMessage();
            }
        });

        // Handle IME composition for older browsers

À nouveau, simplement avec cette même déclaration de type Python, **FastAPI** vous fournit une documentation interactive automatique (intégrant Swagger UI).

Remarquez que le paramètre de chemin est déclaré comme entier.
