or

```

or any other case variation (uppercase, first letter in uppercase, etc), your function will see the parameter `short` with a `bool` value of `True`. Otherwise as `False`.

## Custom Validation { #custom-validation }

There could be cases where you need to do some **custom validation** that can't be done with the parameters shown above.

In those cases, you can use a **custom validator function** that is applied after the normal validation (e.g. after validating that the value is a `str`).
