sum() list from SQLAlchemy output

[Personne]

Hello guys,

I'm sure it is simple. Have a SQLAlchemy query such as:

qp = db.session.query(UInventory, func.sum(UInventory.quantity).label('total')).filter(
            UInventory.location_id == s.loc_id, UInventory.userid == current_user.userid).group_by(UInventory.part_id). subq.all()

Later in my code, I want to sum up the result of the 'total' from the query.

for now I'm using this code, which works well, but I'd like to use sum() function instead:

sum = 0
for q in qp:
    sum += q.total

the type of the variable q is <class 'sqlalchemy.engine.row.Row'>

I tried

max_total = sum(q.total) 

but of course I got this error:

Error:
print(sum(qp.total))
AttributeError: 'list' object has no attribute 'total'

How can I achieve something that simple ?

Thank you

Note: I do not want a SQL query solution !
