/// tip | Подсказка

Обычно это нужно сделать только **один раз**, при создании виртуального окружения.

///

## Деактивация виртуального окружения { #deactivate-the-virtual-environment }

/// tip | Tipp

Normalerweise müssen Sie dies nur **einmal** tun, wenn Sie die virtuelle Umgebung erstellen.

///

## Die virtuelle Umgebung deaktivieren { #deactivate-the-virtual-environment }

///

////

Esse comando cria um novo ambiente virtual em um diretório chamado `.venv`.

/// details | `.venv` ou outro nome

Você pode criar o ambiente virtual em um diretório diferente, mas há uma convenção para chamá-lo de `.venv`.

///

## Ative o ambiente virtual { #activate-the-virtual-environment }

///

When you work in Python projects you probably should use a **virtual environment** (or a similar mechanism) to isolate the packages you install for each project.

/// info

If you already know about virtual environments, how to create them and use them, you might want to skip this section. 🤓

///

/// tip

A **virtual environment** is different than an **environment variable**.

        return relatedQueryMap.size();
    }

    /**
     * Extracts the virtual host key from a RelatedQuery entity.
     * If the virtual host is blank or null, returns an empty string.
     *
     * @param entity the RelatedQuery entity to extract the host key from
     * @return the virtual host key, or empty string if blank or null
     */
    protected String getHostKey(final RelatedQuery entity) {

    }

    /**
     * Extracts the virtual host key from a RelatedContent entity.
     * If the virtual host is blank or null, returns an empty string.
     * This key is used to organize related content by virtual host.
     *
     * @param entity the RelatedContent entity to extract the host key from
     * @return the virtual host key, or empty string if not specified
     */

Apenas tenha em mente que quando você ler "servidor" em geral, isso pode se referir a uma dessas duas coisas.

Para usar o `TestClient`, primeiro instale o <a href="https://www.python-httpx.org" class="external-link" target="_blank">`httpx`</a>.

Certifique-se de criar um [ambiente virtual](../virtual-environments.md){.internal-link target=_blank}, ativá-lo e instalá-lo, por exemplo:

```console

Importe `TestClient`.

Para recibir archivos subidos y/o form data, primero instala <a href="https://github.com/Kludex/python-multipart" class="external-link" target="_blank">`python-multipart`</a>.

Asegúrate de crear un [entorno virtual](../virtual-environments.md){.internal-link target=_blank}, actívalo y luego instálalo, por ejemplo:

```console
$ pip install python-multipart
