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

By doing that, your editor can provide support even while processing items from the list:

<img src="/img/python-types/image05.png">

Without types, that's almost impossible to achieve.

Notice that the variable `item` is one of the elements in the list `items`.

Sadece standart **Python**.

Örneğin bir `int` için:

```Python
item_id: int
```

ya da daha karmaşık bir `Item` modeli için:

```Python
item: Item
```
