Estos son objetos de **JavaScript**, no strings, por lo que no puedes pasarlos directamente desde código de Python.

## Ejemplo

Aquí tienes un ejemplo de una *path operation* con parámetros usando algunos de los tipos anteriores.

{* ../../docs_src/extra_data_types/tutorial001_an_py310.py hl[1,3,12:16] *}

```

These are **JavaScript** objects, not strings, so you can't pass them from Python code directly.
