## Omgevingsvariabelen uitlezen in Python

Je kunt omgevingsvariabelen **buiten** Python aanmaken, in de terminal (of met een andere methode) en ze vervolgens **in Python uitlezen**.

Je kunt bijvoorbeeld een bestand `main.py` hebben met:

```Python hl_lines="3"
import os

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

/// tip

```

</div>

////

## Read env vars in Python

You could also create environment variables **outside** of Python, in the terminal (or with any other method), and then **read them in Python**.

For example you could have a file `main.py` with:

```Python hl_lines="3"
import os

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

/// tip
