/// 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.

If not provided, it's `None` by default, here we provide `"World"` as the default value to use.

///

Then you could call that Python program:

//// tab | Linux, macOS, Windows Bash

<div class="termy">

```console

	defer logger.AuditLog(ctx, w, r, mustGetClaimsFromToken(r))

	// This only checks if the action (kms:ListKeys) is allowed, it does not check
	// each key name against the policy's Resources. We check that below, once
	// we have the list of key names from the KMS.
	objectAPI, _ := validateAdminReq(ctx, w, r, policy.KMSListKeysAction)
	if objectAPI == nil {
		return
	}

	if GlobalKMS == nil {

```

<a href="https://docs.python.org/3.8/library/os.html#os.getenv" class="external-link" target="_blank">`os.getenv()`</a> 의 두 번째 인자는 반환할 기본값입니다.

여기서는 `"World"`를 넣었기에 기본값으로써 사용됩니다. 넣지 않으면 `None` 이 기본값으로 사용됩니다.

///

그러면 해당 파이썬 프로그램을 다음과 같이 호출할 수 있습니다:

//// tab | Linux, macOS, Windows Bash

<div class="termy">

```console
// Here we don't set the env var yet
$ python main.py

		rs.Completed = true
	case replication.Pending:
		rs.Pending = true
	case replication.Failed:
		rs.Failed = true
		rs.Err = err
	}
}

// GetAll returns replication metrics for all buckets at once.
func (r *ReplicationStats) GetAll() map[string]BucketReplicationStats {
	if r == nil {
		return map[string]BucketReplicationStats{}
	}

	r.RLock()

```

/// tip | Dica

O segundo argumento para <a href="https://docs.python.org/3.8/library/os.html#os.getenv" class="external-link" target="_blank">`os.getenv()`</a> é o valor padrão a ser retornado.

Se não for fornecido, é `None` por padrão, Aqui fornecemos `"World"` como o valor padrão a ser usado.

///

Então você poderia chamar esse programa Python:

//// tab | Linux, macOS, Windows Bash
