Например, у вас есть файл `main.py`:

```Python hl_lines="3"
import os

name = os.getenv("MY_NAME", "World")
print(f"Hello {name} from Python")
```

/// tip | Совет

Второй аргумент [`os.getenv()`](https://docs.python.org/3.8/library/os.html#os.getenv) - это возвращаемое по умолчанию значение.

Наприклад, у вас може бути файл `main.py` з:

```Python hl_lines="3"
import os

name = os.getenv("MY_NAME", "World")
print(f"Hello {name} from Python")
```

/// tip | Порада

Другий аргумент до [`os.getenv()`](https://docs.python.org/3.8/library/os.html#os.getenv) - це значення за замовчуванням, яке буде повернено.
