No; what are you trying to do? You might be able to check whether the 
entity has a key and if so, whether that key isn't incomplete:

if ent.key and ent.key.id():
  # It has a complete key.
else:
  # Hasn't been written, ever. 

However this can be fooled if you explicitly set the key or the id when you 
create an entity, e.g.

ent = Employee(id='joe')

or

ent = Employee(key=ndb.Key(Employee, 'joe'))

(These two are equivalent.)
