> Modern versions of Python have support for **"asynchronous code"** using something called **"coroutines"**, with **`async` and `await`** syntax.

That should make more sense now. ✨

All that is what powers FastAPI (through Starlette) and what makes it have such an impressive performance.

        def title = typeTable.title[0].text()

        //TODO below checks makes it harder to add new sections
        //because the new section will work correctly only when the section title ends with 'types' :)
        if (title.matches('(?i).* types')) {

И мы знаем, что редакторы кода не могут обеспечить достаточную поддержку (например, автозавершение) для `dict`, поскольку они не могут знать их ключи и типы значений.

Мы можем сделать лучше...

## Что делает зависимость { #what-makes-a-dependency }

До сих пор вы видели зависимости, объявленные как функции.

Но это не единственный способ объявления зависимостей (хотя он, вероятно, более распространенный).

Having a default value of any type, including `None`, makes the parameter optional (not required).

When we don't need to declare more validations or metadata, we can make the `q` query parameter required just by not declaring a default value, like:

```Python
q: str
