    client ->> dep_req: Start request

```console
$ python myapp.py
```

</div>

тоді внутрішня змінна `__name__`, яка створюється автоматично Python, матиме значення `"__main__"`.

Отже, цей блок коду:

```Python
    uvicorn.run(app, host="0.0.0.0", port=8000)
```

буде виконаний.

heavy background computation and you don't necessarily need it to be run by the same process (for example, you don't need to share memory, variables, etc), you might benefit from using other bigger tools like <a href="https://docs.celeryq.dev" class="external-link" target="_blank">Celery</a>.

They tend to require more complex configurations, a message/job queue manager, like RabbitMQ or Redis, but they allow you to run background tasks in multiple processes, and especially, in multiple servers....
