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

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.

Por ejemplo, podrías tener un archivo `main.py` con:

```Python hl_lines="3"
import os

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

/// tip | Consejo

El segundo argumento de <a href="https://docs.python.org/3.8/library/os.html#os.getenv" class="external-link" target="_blank">`os.getenv()`</a> es el valor por defecto a retornar.

    object : ThreadFactory {
      private var nextId = 1

      override fun newThread(runnable: Runnable): Thread = Thread(runnable, "$name-${nextId++}")
    }
}

fun getEnv(name: String) = System.getenv(name)

val SYSTEM_FILE_SYSTEM = FileSystem.SYSTEM

            if (connected) {
                return;
            }
            final String endpoint = System.getenv().get("S3_ENDPOINT");
            final String accessKey = System.getenv().get("S3_ACCESS_KEY");
            final String secretKey = System.getenv().get("S3_SECRET_KEY");
            final String region = System.getenv().getOrDefault("S3_REGION", "us-east-1");

            // Validate endpoint before attempting connection

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 <a href="https://docs.python.org/3.8/library/os.html#os.getenv" class="external-link" target="_blank">`os.getenv()`</a> - это возвращаемое по умолчанию значение.

                return;
            }
            final String endpoint = System.getenv().get("STORAGE_ENDPOINT");
            final String accessKey = System.getenv().get("STORAGE_ACCESS_KEY");
            final String secretKey = System.getenv().get("STORAGE_SECRET_KEY");
            final String region = System.getenv().get("STORAGE_REGION");

            // Validate endpoint before attempting connection
