Первая часть функции, до `yield`, будет выполнена до запуска приложения.

А часть после `yield` будет выполнена после завершения работы приложения.

### Асинхронный менеджер контекста { #async-context-manager }

Если присмотреться, функция декорирована `@asynccontextmanager`.

Это превращает функцию в «асинхронный менеджер контекста».

...and declare its type as the model you created, `Item`.

## Results { #results }

With just that Python type declaration, **FastAPI** will:

* Read the body of the request as JSON.
* Convert the corresponding types (if needed).
* Validate the data.
    * If the data is invalid, it will return a nice and clear error, indicating exactly where and what was the incorrect data.

    // The top bit is set, which means that the double value is going to come from the top 53 bits.
    // So we can ignore the bottom 11, except for rounding. We can unsigned-shift right 1, aka
    // unsigned-divide by 2, and convert that. Then we'll get exactly half of the desired double
    // value. But in the specific case where the bottom two bits of the original number are 01, we
    // want to replace that with 1 in the shifted value for correct rounding.

   * the behavior described in {@link #put(Range, Object) put(range, value)}, however the ranges
   * returned from {@link #asMapOfRanges} will be different if there were existing entries which
   * connect to the given range and value.
   *
   * <p>Even if the input range is empty, if it is connected on both sides by ranges mapped to the
   * same value those two ranges will be coalesced.

- `kubectl config set-context` can now set attributes of the current context, such as the current namespace, by passing `--current` instead of a specific context name ([#66140](https://github.com/kubernetes/kubernetes/pull/66140), [@liggitt](https://github.com/liggitt))

Notice how no connect events are fired for the second call. It reused the connection from the first request for dramatically better performance.
