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

/// tip | Dica

Para isso funcionar, você precisa executar `pip install python-dotenv`.

### O arquivo `.env` { #the-env-file }

Você poderia ter um arquivo `.env` com:

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

		os.Setenv("CONSOLE_STS_DURATION", valueSts)
	} else if valueSession := env.Get(config.EnvBrowserSessionDuration, ""); valueSession != "" {
		os.Setenv("CONSOLE_STS_DURATION", valueSession)
	}

	os.Setenv("CONSOLE_MINIO_SITE_NAME", globalSite.Name())
	os.Setenv("CONSOLE_MINIO_SITE_REGION", globalSite.Region())
	os.Setenv("CONSOLE_MINIO_REGION", globalSite.Region())

    monkeypatch.setenv("ADMIN_EMAIL", "******@****.***")
    settings = main_mod.get_settings()
    assert settings.app_name == "Awesome API"
    assert settings.admin_email == "******@****.***"
    assert settings.items_per_user == 50


def test_endpoint(main_mod: ModuleType, monkeypatch: MonkeyPatch):
    monkeypatch.setenv("ADMIN_EMAIL", "******@****.***")

    if (inheritDevelocityAccessToken) {
        System.getenv("DEVELOCITY_ACCESS_KEY")?.let {
            environment["DEVELOCITY_ACCESS_KEY"] = it
        }
    }
}

fun makePropagatedEnvironment(): MutableMap<String, String> {
    val result = HashMap<String, String>()
    for (key in propagatedEnvironmentVariables) {
        val value = System.getenv(key)
        if (value != null) {

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")
```

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.
