# Змінні оточення { #environment-variables }

/// tip | Порада

Якщо ви вже знаєте, що таке «змінні оточення» і як їх використовувати, можете пропустити цей розділ.

///

Змінна оточення (також відома як «env var») - це змінна, що існує поза кодом Python, в операційній системі, і може бути прочитана вашим кодом Python (а також іншими програмами).

Змінні оточення корисні для роботи з налаштуваннями застосунку, як частина встановлення Python тощо.

That command will create or modify some [environment variables](environment-variables.md) that will be available for the next commands.

One of those variables is the `PATH` variable.

/// tip

You can learn more about the `PATH` environment variable in the [Environment Variables](environment-variables.md#path-environment-variable) section.

To understand environment variables you can read [Environment Variables](../environment-variables.md).

## Types and validation { #types-and-validation }

These environment variables can only handle text strings, as they are external to Python and have to be compatible with other programs and the rest of the system (and even with different operating systems, as Linux, Windows, macOS).
