Try this:

ndb.Key(category, int(id)).delete()

You need to convert the id to integer in order to build a numeric (id) key instead of a name key.

Just curious, doesn't ndb allow us to have string ids? Is not related to the question perhaps, and this already solved his problem. – 0xc0de Sep 05 '13 at 04:31
@0xc0de of course, if you want to control the id you need to pass a string – Shay Erlichmen Sep 05 '13 at 08:28
