how do I return the entity ID using python in GAE?
Assuming I have following
class Names(db.Model):
name = db.StringProperty()

You retrieve the entity, e.g. with a query, then you call .key().id()
on that entity (will be None
if the entity has no numeric id; see here for other info you can retrieve from a Key
object).
The question has long been answered by the Martelli-bot ;-)
I wanted to add some full examples hopefully while not stepping on any toes.
Getting an entity using a query; just getting the keys is faster and uses less CPU than retrieving the full entity:
query = Names.all(keys_only=True)
names = query.get() # this is a shorter equivalent to `query.fetch(limit=1)`
names.id()
From a template:
{{ names.id }}
GQL alternative, as suggested in a comment:
from google.appengine.ext import db
query = db.GqlQuery("SELECT __key__ FROM Names")
names = query.get()
names.id()
