///

/// tip

Remember that in most of the cases, when something is required, you can simply omit the default, so you normally don't have to use `...`.

///

## Query parameter list / multiple values

/// tip

This is a somewhat advanced technique, and in most of the cases you won't really need it, as you can raise exceptions (including `HTTPException`) from inside of the rest of your application code, for example, in the *path operation function*.

But it's there for you if you need it. 🤓
