## `async` y `await` { #async-and-await }

Las versiones modernas de Python tienen una forma muy intuitiva de definir código asíncrono. Esto hace que se vea igual que el código "secuencial" normal y hace el "wait" por ti en los momentos adecuados.

Cuando hay una operación que requerirá esperar antes de dar los resultados y tiene soporte para estas nuevas funcionalidades de Python, puedes programarlo así:

```Python

				t.Errorf("failed to find user, got error: %v", err)
			} else if len(users) != 2 {
				t.Errorf("should find 2 users, but got %d", len(users))
			}
			sg.Done()
		}()
	}
	sg.Wait()
}

func TestGenericsWithTransaction(t *testing.T) {
	ctx := context.Background()
	tx := DB.Begin()
	if tx.Error != nil {
		t.Fatalf("failed to begin transaction: %v", tx.Error)
	}

<a href="/pkg/sync/#Map">lock-free maps</a>,
<a href="/pkg/sync/#Pool">allocation pools</a>,
and
<a href="/pkg/sync/#WaitGroup">wait groups</a>.
The documentation for each of these specifies the guarantees it
makes concerning synchronization.

   * The {@link Iterators} analog to this method is {@link Iterators#getNext}.
   *
   * <p>If no default value is desired (and the caller instead wants a {@link
   * NoSuchElementException} to be thrown), it is recommended that {@code
   * iterable.iterator().next()} is used instead.
