Prefer to use the `Annotated` version if possible.

    ```Python hl_lines="13"
    {!> ../../../docs_src/query_params_str_validations/tutorial008.py!}
    ```

## Alias parameters

Imagine that you want the parameter to be `item-query`.

Like in:

```
http://127.0.0.1:8000/items/?item-query=foobaritems
```

But `item-query` is not a valid Python variable name.
