I'm using this extensively so I wanted to add more information in case

.key() in a function
.key in a Django template
...yields just the long alphanumeric string that the Datastore uses
internally.

.key().name() in a function
.key.name in a Django template
...yields the custom key_name you used when creating the entity.

There are other instance methods on the Key class to get the id, or
id_or_name, etc.:
