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

The second argument to <a href="https://docs.python.org/3.8/library/os.html#os.getenv" class="external-link" target="_blank">`os.getenv()`</a> is the default value to return.

For this to work, you need to `pip install python-dotenv`.

### The `.env` file { #the-env-file }

You could have a `.env` file with:

```bash
ADMIN_EMAIL="******@****.***"
APP_NAME="ChimichangApp"
```
