Todo **FastAPI** está basado en estos type hints, lo que le da muchas ventajas y beneficios.

Pero, así nunca uses **FastAPI** te beneficiarás de aprender un poco sobre los type hints.

Si eres un experto en Python y ya lo sabes todo sobre los type hints, salta al siguiente capítulo.

Comencemos con un ejemplo simple:

			t.Errorf("wrong header for %s: got %s want %s", v.key, res,
				v.expected)
		}
	}
