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**.

設定例:

* [VS Code](https://code.visualstudio.com/docs/python/environments#_select-and-activate-an-environment)
* [PyCharm](https://www.jetbrains.com/help/pycharm/creating-virtual-environment.html)

/// tip | 豆知識

この設定は通常、仮想環境を作成した際に**一度だけ**行います。

///

## 仮想環境の無効化 { #deactivate-the-virtual-environment }

プロジェクトの作業が終了したら、その仮想環境を**無効化**できます。

<div class="termy">

```console

例如：

* [VS Code](https://code.visualstudio.com/docs/python/environments#_select-and-activate-an-environment)
* [PyCharm](https://www.jetbrains.com/help/pycharm/creating-virtual-environment.html)

/// tip | 提示

通常你只需要在创建虚拟环境时执行此操作**一次**。

///

## 退出虚拟环境 { #deactivate-the-virtual-environment }

当你完成工作后，你可以**退出**虚拟环境。

<div class="termy">

```console
$ deactivate

```

</div>

////

Bu komut, sonraki komutlarda kullanılabilecek bazı [environment variable](environment-variables.md)'ları oluşturur veya değiştirir.

Bunlardan biri `PATH` değişkenidir.

/// tip | İpucu

`PATH` environment variable hakkında daha fazla bilgiyi [Environment Variables](environment-variables.md#path-environment-variable) bölümünde bulabilirsiniz.

///

例如：

* [VS Code](https://code.visualstudio.com/docs/python/environments#_select-and-activate-an-environment)
* [PyCharm](https://www.jetbrains.com/help/pycharm/creating-virtual-environment.html)

/// tip

通常你只需要在建立虛擬環境時執行此操作**一次**。

///

## 退出虛擬環境 { #deactivate-the-virtual-environment }

當你完成工作後，你可以**退出**虛擬環境。

<div class="termy">

```console
$ deactivate

Наприклад:

* [VS Code](https://code.visualstudio.com/docs/python/environments#_select-and-activate-an-environment)
* [PyCharm](https://www.jetbrains.com/help/pycharm/creating-virtual-environment.html)

/// tip | Порада

Зазвичай це потрібно робити лише один раз, коли ви створюєте віртуальне середовище.

///

## Деактивуйте віртуальне середовище { #deactivate-the-virtual-environment }

* [VS Code](https://code.visualstudio.com/docs/python/environments#_select-and-activate-an-environment)
* [PyCharm](https://www.jetbrains.com/help/pycharm/creating-virtual-environment.html)

/// tip | Consejo

Normalmente solo tendrías que hacer esto **una vez**, cuando crees el entorno virtual.

///

## Desactiva el Entorno Virtual { #deactivate-the-virtual-environment }

* [VS Code](https://code.visualstudio.com/docs/python/environments#_select-and-activate-an-environment)
* [PyCharm](https://www.jetbrains.com/help/pycharm/creating-virtual-environment.html)

/// tip | Dica

Normalmente, você só precisa fazer isso **uma vez**, ao criar o ambiente virtual.

///

## Desativar o ambiente virtual { #deactivate-the-virtual-environment }

예를 들면:

* [VS Code](https://code.visualstudio.com/docs/python/environments#_select-and-activate-an-environment)
* [PyCharm](https://www.jetbrains.com/help/pycharm/creating-virtual-environment.html)

/// tip

보통 이 설정은 가상 환경을 만들 때 **한 번만** 하면 됩니다.

///

## 가상 환경 비활성화 { #deactivate-the-virtual-environment }

프로젝트 작업을 마쳤다면 가상 환경을 **비활성화**할 수 있습니다.
