De waarde van de variabele `PATH` is een lange string die bestaat uit mappen die gescheiden worden door een dubbele punt `:` op Linux en macOS en door een puntkomma `;` op Windows.

De omgevingsvariabele `PATH` zou er bijvoorbeeld zo uit kunnen zien:

//// tab | Linux, macOS

```plaintext

The value of the variable `PATH` is a long string that is made of directories separated by a colon `:` on Linux and macOS, and by a semicolon `;` on Windows.

For example, the `PATH` environment variable could look like this:

//// tab | Linux, macOS

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

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

Activating a virtual environment adds its path `.venv/bin` (on Linux and macOS) or `.venv\Scripts` (on Windows) to the `PATH` environment variable.

Let's say that before activating the environment, the `PATH` variable looked like this:

//// tab | Linux, macOS

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

That means that the system would look for programs in:

Значение переменной `PATH` - это длинная строка, состоящая из каталогов, разделенных двоеточием `:` в Linux и macOS, и точкой с запятой `;` в Windows.

Например, переменная окружения `PATH` может выглядеть следующим образом:

//// tab | Linux, macOS

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

build:android --define=xnn_enable_avxvnniint8=false

# Sets the default Apple platform to macOS.
build:macos --apple_platform_type=macos

# gRPC on MacOS requires this #define
build:macos --copt=-DGRPC_BAZEL_BUILD

# Avoid hitting command line argument limit
build:macos --features=archive_param_file

# Settings for MacOS on ARM CPUs.
build:macos_arm64 --cpu=darwin_arm64
build:macos_arm64 --macos_minimum_os=11.0

A ativação de um ambiente virtual adiciona seu caminho `.venv/bin` (no Linux e macOS) ou `.venv\Scripts` (no Windows) à variável de ambiente `PATH`.

Digamos que antes de ativar o ambiente, a variável `PATH` estava assim:

//// tab | Linux, macOS

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

Isso significa que o sistema procuraria programas em:

Sie können Umgebungsvariablen in der Shell erstellen und verwenden, ohne Python zu benötigen:

//// tab | Linux, macOS, Windows Bash

<div class="termy">

```console
// Sie könnten eine Umgebungsvariable MY_NAME erstellen mittels
$ export MY_NAME="Wade Wilson"

// Dann könnten Sie diese mit anderen Programmen verwenden, etwa
