With this you should have a basic understanding of what **environment variables** are and how to use them in Python.

You can also read more about them in the <a href="https://en.wikipedia.org/wiki/Environment_variable" class="external-link" target="_blank">Wikipedia for Environment Variable</a>.

Благодаря этому вы должны иметь базовое представление о том, что такое **переменные окружения** и как использовать их в Python.

Подробнее о них вы также можете прочитать в <a href="https://en.wikipedia.org/wiki/Environment_variable" class="external-link" target="_blank">статье о переменных окружения на википедии</a>.
