Answer 1

For the case when you need to find minimum and maximum values for the score field. You can do this with a one query using min and max functions:

from sqlalchemy.sql import func
qry = session.query(func.max(Player.score).label("max_score"), 
                func.min(Player.score).label("min_score"),
                )
res = qry.one()
max = res.max_score
min = res.min_score
