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

Modern versions of Python have a very intuitive way to define asynchronous code. This makes it look just like normal "sequential" code and do the "awaiting" for you at the right moments.

When there is an operation that will require waiting before giving the results and has support for these new Python features, you can code it like:

```Python
burgers = await get_burgers(2)
```

			}
			return u, errNoSuchUser
		}
		u.Credentials.Claims = jwtClaims.Map()
	}

	if u.Credentials.Description == "" {
		u.Credentials.Description = u.Credentials.Comment
	}

	return u, nil
}

	userIdentities := make([]UserIdentity, len(users))
