#### Using just `list` { #using-just-list }

You can also use `list` directly instead of `list[str]`:

/// note

Keep in mind that in this case, FastAPI won't check the contents of the list.

For example, `list[int]` would check (and document) that the contents of the list are integers. But `list` alone wouldn't.
