И вы, скорее всего, не захотите, чтобы приложение оставалось «мёртвым» из‑за ошибки в одном месте — вы захотите, чтобы оно **продолжало работать** хотя бы для *операций пути*, которые не сломаны.

### Перезапуск после падения { #restart-after-crash }

В случаях действительно серьёзных ошибок, которые роняют работающий **процесс**, вам понадобится внешний компонент, отвечающий за **перезапуск** процесса, как минимум пару раз...

### Перезапуск після краху { #restart-after-crash }

Але в таких випадках із серйозними помилками, що призводять до краху запущеного **процесу**, потрібен зовнішній компонент, відповідальний за **перезапуск** процесу, принаймні кілька разів...

We are importing the submodule `items` directly, instead of importing just its variable `router`.

This is because we also have another variable named `router` in the submodule `users`.

If we had imported one after the other, like:

```Python
from .routers.items import router
from .routers.users import router
```
