But you can disable it by setting `syntaxHighlight` to `False`:

{* ../../docs_src/configure_swagger_ui/tutorial001_py39.py hl[3] *}

...and then Swagger UI won't show the syntax highlighting anymore:

Главной возможностью, которую хотелось взять из Django REST Framework, была автоматическая документация API.

        "info": {"title": "FastAPI", "version": "0.1.0"},
        "paths": {
            "/teleport": {
                "get": {

    assert response.status_code == 200, response.text
    assert response.json() == {}


def test_openapi():

    assert response.status_code == 200, response.text
    assert response.json() == {

@pytest.mark.parametrize(
    "path",
    [
        "/required-bytes",
        "/required-uploadfile",
    ],
)
def test_required_schema(path: str):
    openapi = app.openapi()
    body_model_name = get_body_model_name(openapi, path)

    assert app.openapi()["components"]["schemas"][body_model_name] == {
        "properties": {

Pero puedes desactivarlo estableciendo `syntaxHighlight` en `False`:

{* ../../docs_src/configure_swagger_ui/tutorial001_py39.py hl[3] *}

...y entonces Swagger UI ya no mostrará el resaltado de sintaxis:
