Часто всю функциональность использования асинхронного кода с `async` и `await` кратко называют «сопрограммами». Это сопоставимо с ключевой особенностью Go — «goroutines».

## Заключение { #conclusion }

Вернёмся к той же фразе:

> Современные версии Python поддерживают **«асинхронный код»** с помощью **«сопрограмм»** (coroutines) и синтаксиса **`async` и `await`**.

Теперь это должно звучать понятнее. ✨

		// lk2
		lk2ch := make(chan struct{})
		go func() {
			defer close(lk2ch)
			nsLk.lock(ctx, "volume", "path", "source", "opsID", false, 1*time.Millisecond)
		}()
		time.Sleep(1 * time.Millisecond) // wait for goroutine to advance; ref=2

		// Unlock the 1st lock; ref=1 after this line
		nsLk.unlock("volume", "path", false)

		// Taking another lockMapMutex here allows queuing up additional lockers. This should

		return err
	default:
	}
	if _, err := b.store.PutMultiple(b.items); err != nil {
		return err
	}
	b.items = make([]I, 0, b.limit)
	return nil
}

// Close commits the pending items and quits the goroutines
func (b *Batch[I]) Close() error {
	defer func() {
		close(b.quitCh)
	}()

	b.Lock()
	defer b.Unlock()
	return b.commit()
}

// NewBatch creates a new batch

// returns the slice of errors from all function calls.
func (g *NotificationGroup) Wait() []NotificationPeerErr {
	g.workers.Wait()
	return g.errs
}

// Go calls the given function in a new goroutine.
//
// The first call to return a non-nil error will be
// collected in errs slice and returned by Wait().
func (g *NotificationGroup) Go(ctx context.Context, f func() error, index int, addr xnet.Host) {

Mais toutes ces fonctionnalités d'utilisation de code asynchrone avec `async` et `await` sont souvent résumées comme l'utilisation des *coroutines*. On peut comparer cela à la principale fonctionnalité clé de Go, les "Goroutines".

## Conclusion

Reprenons la phrase du début de la page :

> Les versions modernes de Python supportent le **code asynchrone** grâce aux **"coroutines"** avec les syntaxes **`async` et `await`**.

		sleep := min(unit*time.Duration(1<<attempt), maxSleep)
		sleep -= time.Duration(r.Float64() * float64(sleep-unit))
		return sleep
