Digamos que instalas Python y termina en un directorio `/opt/custompython/bin`.

Si dices que sí para actualizar la variable de entorno `PATH`, entonces el instalador añadirá `/opt/custompython/bin` a la variable de entorno `PATH`.

Podría verse así:

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

    val perfTestJavaVersion: JvmVersion = JvmVersion.JAVA_17,
    val defaultArch: Arch = Arch.AMD64,
) {
    LINUX(
        "Linux",
        androidHome = "/opt/android/sdk",
        jprofilerHome = "/opt/jprofiler/jprofiler11.1.4",
    ),
    ALPINE(
        "Linux",
        androidHome = "/not/supported",
        jprofilerHome = "/not/supported",
    ),
    WINDOWS(
        "Windows",

Giả sử bạn cài đặt Python vào thư mục `C:\opt\custompython\bin`.

Nếu bạn chọn cập nhật biến môi trường `PATH`, thì cài đặt sẽ thêm `C:\opt\custompython\bin` vào biến môi trường `PATH`.

Nó có thể có dạng như sau:

```plaintext
C:\Program Files\Python312\Scripts;C:\Program Files\Python312;C:\Windows\System32;C:\opt\custompython\bin

    Note over client,operation: Response is already sent, can't change it anymore
    opt Tasks
        operation -->> tasks: Send background tasks
    end
    opt Raise other exception
        tasks -->> dep: Raise other exception
    end
    Note over dep: After yield
    opt Handle other exception
        dep -->> dep: Handle exception, can't change response. E.g. close DB session.
    end
```
