App engine datastore - searching a list of entities

I have pulled a list of entities from my datastore in app engine. Each entity in the list has a "name" attribute. Is there a quick way to search the list of entities for a specific name?

As opposed to iterating through each one and checking the name attribute

Thanks!

You can pull out the entity you are looking for directly if you have an attribute you can match against

q = Person.all()
q.filter("name =", target_last_name)
result = q.get()

But as far as I know, you have to iterate around the result list if you are not querying against a specific attribute.

This link talks about efficent ways to do that however:

Searching a list of objects in Python

E.G.

     [x for x in myList if x.n == 30]
