In this case, `str` is the type parameter passed to `List` (or `list` in Python 3.9 and above).

///

That means: "the variable `items` is a `list`, and each of the items in this list is a `str`".

/// tip

If you use Python 3.9 or above, you don't have to import `List` from `typing`, you can use the same regular `list` type instead.
