```Python
say_hi(name=None)  # This works, None is valid 🎉
```

The good news is, once you are on Python 3.10 you won't have to worry about that, as you will be able to simply use `|` to define unions of types:

{* ../../docs_src/python_types/tutorial009c_py310.py hl[1,4] *}

And then you won't have to worry about names like `Optional` and `Union`. 😎

#### Generic types

```

Het goede nieuws is dat als je eenmaal Python 3.10 gebruikt, je je daar geen zorgen meer over hoeft te maken, omdat je dan gewoon `|` kunt gebruiken om unions van types te definiëren:

```Python hl_lines="1  4"
{!../../docs_src/python_types/tutorial009c_py310.py!}
```

Dan hoef je je geen zorgen te maken over namen als `Optional` en `Union`. 😎

        # Don't remove en dist_path as it might already contain other languages.
        # When running build_all(), that function already removes site_path.
        # All this is only relevant locally, on GitHub Actions all this is done through
        # artifacts and multiple workflows, so it doesn't matter if directories are
        # removed or not.
    else:
        dist_path = site_path / lang
