How to access properties of Datastore query (App Engine, python)

Question

I'm going nuts trying to access the properties of a Datastore query. I could not find anything in the documentation (it could be me).

In the datastore I have the following:

Here's a snippet of my main.py:

import all the necessary stuff
...
datastore_client = datastore.Client()
u_name = 'batman' # example of the user I want to find
qn = datastore_client.query(kind='user').add_filter('user_id', '=', u_name).fetch()

So far so good, but how do I access the properties of this query?

What I haven't been able to find is how do I access the first_name of user 'batman'? Something like:

name = qn.somefuntion('first_name')

Could someone tell me how to do this and also point me to the respective documentation?

Thanks!

Check out the python library reference for an Entity. The key part there is "you can treat an entity like a regular Python dictionary."

for entity in qn:
    print(entity['first_name'])
