Would like to extend @zzzeek's answer. Indeed Query has column_descriptions attribute but it's not available for all the methods.

Consider the following two queries:

1. query = session.query(Projects).filter_by()
2. query = session.query(Projects).all() <-- This query does not have column_descriptions.

So if you come across this situation where you need to use column_descriptions attribute but using ...query(...).all() then you can change it to ...query(...).filter_by() i.e. filter_by() without any filter condition.
