How To Use NDB Query Without Knowing Class Name

I'm writing a Python app on Google App Engine and I need to have an ndb query but the problem is that the query can be on different class types so I'm looking for a method other than clss.Query(). I need clss to be a variable. Also could I possibly use a filter with that?

There is in fact a way to do this that is mentioned in the documentation:

from google.appengine.ext import ndb
ndb.Query(kind=clss)

You could also use filters, either by passing the filter as a parameter in the query:

ndb.Query(kind=clss, filters=...)

or by applying a filter() on the query like you would usually do:

ndb.Query(kind=clss).filter()
