## Add the background task { #add-the-background-task }

Inside of your *path operation function*, pass your task function to the *background tasks* object with the method `.add_task()`:

{* ../../docs_src/background_tasks/tutorial001_py39.py hl[14] *}

`.add_task()` receives as arguments:

## Headers reenviados por el proxy { #proxy-forwarded-headers }

### Múltiplas Aplicações { #multiple-applications }

Podem existir múltiplas aplicações em execução no mesmo servidor (ou servidores), por exemplo: outras APIs ou um banco de dados.

This tutorial shows you how to use **FastAPI** with most of its features, step by step.

Each section gradually builds on the previous ones, but it's structured to separate topics, so that you can go directly to any specific one to solve your specific API needs.

It is also built to work as a future reference so you can come back and see exactly what you need.

## Run the code { #run-the-code }

Hay una variable de entorno **especial** llamada **`PATH`** que es utilizada por los sistemas operativos (Linux, macOS, Windows) para encontrar programas a ejecutar.

El valor de la variable `PATH` es un string largo que consiste en directorios separados por dos puntos `:` en Linux y macOS, y por punto y coma `;` en Windows.

Por ejemplo, la variable de entorno `PATH` podría verse así:

//// tab | Linux, macOS

Por ejemplo, "**Python 3.6+**" significa que es compatible con Python 3.6 o superior (incluyendo 3.7, 3.8, 3.9, 3.10, etc). Y "**Python 3.9+**" significa que es compatible con Python 3.9 o superior (incluyendo 3.10, etc).

Si puedes usar las **últimas versiones de Python**, utiliza los ejemplos para la última versión, esos tendrán la **mejor y más simple sintaxis**, por ejemplo, "**Python 3.10+**".

O valor da variável `PATH` é uma longa string composta por diretórios separados por dois pontos `:` no Linux e macOS, e por ponto e vírgula `;` no Windows.

Por exemplo, a variável de ambiente `PATH` poderia ter esta aparência:

//// tab | Linux, macOS

```plaintext
/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin
```

///

## Запуск вашего кода с помощью отладчика { #run-your-code-with-your-debugger }

Так как вы запускаете сервер Uvicorn непосредственно из вашего кода, вы можете вызвать Python программу (ваше FastAPI приложение) напрямую из отладчика.
